Microsoft Launches Free On-Demand Virus/Malware Scanner

Friendly Computers found this article useful and would like to share it with you.

Microsoft has launched a new, free virus/malware scanner, that's designed to be used if you think your computer might be infected.

The program is called the Microsoft Safety Scanner.  To use it, download the file from http://www.microsoft.com/security/scanner/en-us/default.aspx and then run it on your PC.  The app is portable, so doesn't need an installer.  When you run it, it will analyze your computer and detect, and remove, many of the most prevalent viruses.

Microsoft points out that this on-demand tool is not a substitute for a proper on-access antivirus product.  It's simply designed to be used in emergencies, such as if you think your computer may have a problem that has managed to sneak past your existing defences.  Also, note that the program automatically expires after 10 days, so if you want to run it regularly you'll need to keep downloading the latest version.

At first glance, Safety Scanner is a welcome addition to Microsoft's range of free security tools, of which its Security Essentials suite is probably the best known.  But at 67 MB for the download, for a program that expires after 10 days, we can't work out why it needs to be so huge.  McAfee offers a similar product, which is also free, called Stinger.  It doesn't expire after 10 days, can be downloaded from http://www.mcafee.com/us/downloads/free-tools/how-to-use-stinger.aspx, and runs to just a 7.7 MB download.

Six Windows 7 Nightmares (and How to Fix Them)

Friendly Computers would like to help you to fix these Windows 7 nightmares.

You sit up suddenly in a cold sweat, and scream. But you're in bed, and it was just a bad dream. Sighing with relief, you get up, get dressed, go to work, and turn on your PC.

Then you sit up suddenly in a cold sweat, and scream--but this time, it's not a dream. It's a Windows nightmare.

Compared with its predecessors, Windows 7 is remarkably secure and dependable. It's far from perfect, though: An unbootable PC, a nasty piece of malware, or a single but important file gone missing can make you lose days or even months of work. And you can't solve every nightmare by waking up.

Here are ways out of six common Windows 7 disasters. I'll tell you how to fix a PC that won't boot, retrieve files from an inaccessible hard drive, stop frequent Blue Screens of Death, restore a forgotten administrator password, remove malware, and find a missing file.

1. Your PC Won't Boot

If turning on your PC doesn't bring you into Windows, try booting from a Windows 7 DVD or a recovery disc.

Boot from a Windows 7 System Repair Disc, and you'll find tools to heal an unbootable PC.Boot from a Windows 7 System Repair Disc, and you'll find tools to heal an unbootable PC.

You may already have the DVD. If Windows 7 didn't come with your computer but you installed it yourself, you have the disc. If you don't have it, you can borrow someone else's disc.

Alternatively you can borrow someone else's Windows 7 computer and use it to create a System Repair Disc (you can also do this on your own PC before it has a problem). To create the disc, clickStart, type system repair, select Create a System Repair Disc, and follow the prompts.

If your computer won't boot from the CD, go into its setup screen and change the boot order so that the optical or CD/DVD drive comes before the hard drive. I can't tell you exactly how to do this since it differs from one PC to another. When you first turn on the computer, look for an on-screen message telling you to press a particular key 'for setup'.

If your PC fails before you can enter setup or boot from a CD, you have a hardware problem. If you're not comfortable working inside a PC, take it to a professional.

But let's assume that the CD boots. When it does, follow the prompts. Likely the utility will tell you very soon that there's a problem, and it will ask if you want to fix the problem. You do.

If it doesn't ask you, or if the disc can't fix the issue, you'll see a menu with various options.Startup Repair and System Restore are both worth trying.

2. You Can't Access the Hard Drive

If Windows can't boot because the PC can't read the hard drive, none of the solutions above will work. But that's not the worst of it: Unless you have a very up-to-date backup (and shame on you if you don't), all of your files are locked away on a possibly dead hard drive. Secondary drives you don't boot off of, both internal and external, also can die with important data locked away on them.

If you can't access your hard drive, Recover My Files might be able to do what its name implies.If you can't access your hard drive, Recover My Files might be able to do what its name implies.

If the drive is making noises that you've never heard before, shut off the PC immediately. In that case you have only one possible solution, and it's expensive: Send the drive to a data-retrieval service. Drivesavers and Kroll Ontrack are the best known, although they're not necessarily better than smaller, cheaper companies. Expect to pay hundreds or even thousands of dollars. If your drive sounds okay, however, you may be able to recover the files for only $70 with GetData's Recover My Files.

If the sick drive is the one you use to boot Windows, you'll have to remove it from the PC and access it on another computer. You can do so by making it a secondary drive in a desktop PC, or by using a SATA-USB adapter such as the Bytecc USB 2.0 to IDE/SATA Adapter Kit.

The free, demo version of Recover My Files will show you which files can be recovered (almost all of them, when I tested it) and even display their contents. Once you've paid the $70 license fee, the program can copy the files to another drive. If that doesn't work, you'll need to use a retrieval service.

3. Blue Screens of Death Attack Your PC Regularly

BlueScreenView can show what Windows was doing before disaster struck.BlueScreenView can show what Windows was doing before disaster struck.

One second you're working productively, the next you're staring at a blue screen filled with meaningless white text. If it happens occasionally, you curse, reboot, and get on with your work. If it happens regularly, you have a problem that needs fixing.

Windows 7 keeps logs of these "Stop Errors." (That's Microsoft's term; everyone else calls them "Blue Screens of Death," or BSoDs.) To view the logs and make sense of them, download and run BlueScreenView, a free, portable program by NirSoft (portablemeans you don't have to install it). The program shows you what drivers were running at the time of the crash, and highlights the likeliest suspects. If the same drivers come up from multiple crashes, you should definitely update them.

Speaking of updating drivers, you should make sure that all of them are current. SlimWare Utilities' free SlimDrivers makes this chore remarkably easy, as it scans Windows and lists which drivers need to be updated. If you register (that's free, too), it will find the drivers and run the update for you. It even offers to create a restore point before each update. Don't update all of your drivers at once, however; if you do, and one of them makes things worse, you'll have a tough time figuring out which one.

Frequent BSoDs can also be a sign of hardware problems, especially bad RAM. Although Windows 7 has its own memory-diagnostics program, I prefer the free Memtest86+, which you have to boot separately. You can download the program either as an .iso file--from which you can create a bootable CD--or as an .exe file that will install the program and its bootable operating system onto a flash drive.

4. No One Has the PC's Administrator Password

If the wrong person leaves your company in a huff, one or more PCs could be left stranded. With no one in the company knowing the password to an administrator-level account, you can't install software, change important settings, or possibly access encrypted data.

Fortunately, you can remove the password, letting you log on to that account. You do that with the Offline NT Password & Registry Editor, a bootable, text-based free program that you download as an .iso file. Double-click that file, and Windows 7 will start the process of burning it to a CD.

Sure your drivers are up-to-date? SlimDrivers can automate this otherwise time-consuming job.Sure your drivers are up-to-date? SlimDrivers can automate this otherwise time-consuming job.

Boot the CD and follow these instructions. I've put the on-screen prompts in italics. After you type your answer, press Enter.

boot: Just press Enter.

Select: [1]: Above the prompt you'll see a list of hard-drive partitions. Select the right one by typing that number.

What is the path to the registry directory?...: The default is probably correct. Just press Enter.

[1]: 1

What to do? [1] ->: 1

or simply enter the username...: Type the name of the administrator account. If you're not sure what it is, all of the account names are listed above the prompt.

Select: [q] >: 1

Select: ! - quit...: !

What to do [1]: q

About to write file(s) back...: y

New run? [n]: n

# Remove the CD and reboot.

You should now be able to log on to the administrator account without a password. For security purposes, don't forget to create a new password for the account. Just be sure to remember what it is.

5. You Think Your PC Is Infected

Malwarebytes Anti-Malware might catch malicious software that your regular antivirus program missed.Malwarebytes Anti-Malware might catch malicious software that your regular antivirus program missed.

Is your computer behaving oddly, slowing down at the wrong time, or refusing to run certain programs? It could be infected with malware. What can you do about that?

If your regular antivirus program--the one you already have up and running--hasn't stopped the questionable software, it probably can't. What you need is a second opinion--and possibly a third and a fourth.

Start with the free version of Malwarebytes Anti-Malware, a utility with an exceptional record of finding and removing malware. Download it, install it, launch it, update the database, and then perform a full scan.

Since installing and updating a cleaning utility are tasks that the infection may interfere with, it's a good idea to follow your Malwarebytes scan with other scans that don't require an installation or even an update.

On someone else's PC, download SuperAntiSpyware Portable and copy it to a flash drive. Boot the infected PC into Safe Mode, plug in the flash drive, and run the program. Since SuperAntiSpyware.com updates the portable program every day or two, you don't need to update it before the scan.

For a fourth opinion, try the F-Secure Rescue CD. This is another .iso file from which you can burn a bootable CD. Just boot from the CD and run the scan. The program will try to update its database over the Internet. If it can't, you can download an update on another PC, put it on a flash drive, and keep that plugged in while running F-Secure on the infected PC.

6. An Important File Disappears

You've been working on a report for six weeks. You have to give the speech tomorrow. The PowerPoint presentation is beautiful. It's perfect. It's...where is it?

Maybe you just moved it to another folder. Click the Start menu, type the file's name, and see what turns up.

Can't find a file? Make sure it didn't wind up in the Recycle Bin.Can't find a file? Make sure it didn't wind up in the Recycle Bin.

Nothing? Maybe you've renamed it accidentally. Click Start, type a word that's in the presentation but not in many other files, and see if that gets better results. If it pulls up a lot of results, click See more results so that you can sort the found files by date.

No luck? Try the Recycle Bin. Maybe you deleted the file.

Dead end? Don't panic. You can always restore the file from the backup you made yesterday.

You don't back up? I bet you will now. As for the file you desperately need to find today, you'll have to use file-recovery software. Before I discuss specific programs, I need to lay down one absolute rule about using them: Until you've either recovered the file or given up, do not write to your hard drive. Every time you do so, you lower the odds of successfully retrieving the lost file.

Following this rule requires you to use portable file-recovery software. Download the utility on another PC and save it to a flash drive. Plug that drive into your PC, and launch the program from there.

The rule also means that you shouldn't restore your file to its original location. Save it to the flash drive, as well.

With luck, either of the following two utilities will be able to find and recover your missing file. First, try the free Recuva Portable. It's fast and simple, it can preview image formats, and it works reliably most of the time.

If that doesn't work, try Software Shelf's File-Rescue Plus. It costs $40, but you can recover up to five files with the free demo version. Strictly speaking, File-Rescue Plus isn't portable, but you have a work-around. Install it onto another computer, and then copy the program file, FileRescuePlus.exe, to your flash drive. After you pay the $40, use Notepad to create a file called key.ini containing nothing but the license key that Software Shelf sent you after you bought the program. Place key.ini on the flash drive, in the same folder as the program file.

Lost files and other disasters happen. You can take all the proper precautions, and something could still go horribly wrong, plunging you into a Windows nightmare. But follow these tips, and you should enjoy some sweet dreams.

Windows 7 (Finally) Beats Windows XP's U.S. Desktop Share

Friendly Computers would like to share this article with you.

Someone get the party balloons and slap a big "7" on them, for Windows 7 has finally overtaken its younger brother, Windows XP, in desktop market share. For those keeping score at home or running an office betting pool, the milestone comes just under two years since the release of Windows 7, and a bit over one year since Windows 7 passed Windows Vista's desktop market share.

According to new statistics from Statcounter, Windows 7 now commands 31.71 percent of all U.S. desktops—that's based on the aggregated visitor statistics tracked across approximately three million websites during the month of April. Windows XP now takes up second place in the U.S. desktop market at 31.56 percent, with Vista trailing third at 19.07 percent. And for Apple fans only, OS X currently hovers at a desktop market share of around 14.87 percent.

Looking at the stats over the past year, Windows 7 has been eating away at the desktop share of Windows Vista and Windows XP in equal measure. The desktop share of Apple's OS X has risen slightly from April 2010's 13.24 percent, but its overall growth hasn't experience nearly the same rise of fall as its Microsoft-based brethren.

Windows XP commanded 42.51 percent of the U.S. desktop market in April 2010, and Windows Vista, 27.45 percent. Windows 7 saw half the market penetration of its present-day totals, eating up only 14.7 percent of all U.S. desktops in April of 2010.

As far as worldwide statistics go, however, Windows XP is still the operating system to beat. Although it has lost a bit of its base since the same time period last year, when the OS captured 58.56 percent of the worldwide market, Windows XP is still the most popular operating system on Earth with a total market penetration of 47.19 percent.

Windows 7's growth over the past year has been steady, but the OS still only captures 31.22 percent of the market as of April 2011's figures. Windows Vista is down to 13.24 percent, but still edging out Apple's OS X and its market share of 6.45 percent.

So how long until Windows 7 overtakes all other versions of its operating system to become top dog? Judging by its current trajectory, we can expect to see the swap-on-top to happen sometime within the next year—due to the cannibalization of Windows Vista and Windows XP by Windows 7.

Pingdom has crunched the numbers to find that Windows, in total, isn't much growing in overall market share—rather, you can think of Windows kind of like a hurricane, and the different versions of the operating system are recirculating eyewalls. That's good news for Microsoft upgrade-wise, but bad news for the company's ambitions to increase its overall Windows presence in the desktop space. Then again, since Windows captures more than 90 percent of the desktop market share to begin with, just how much higher can Microsoft realistically go?

How to Remove Win 7 Anti-Spyware 2011 (Fake Anti-Virus Infections)

Friendly Computers found this article useful and would like to share it with you.

If your PC is infected with the Win 7 Anti-Spyware 2011 malware or something similar, you’ve come to the right place, because we’re going to show you how to get rid of it, and free your PC from the awful clutches of this insidious malware (and many others)

Win 7 Anti-Spyware 2011 is just one of many fake antivirus applications like Antivirus Live, Advanced Virus Remover, Internet Security 2010, Security Tool, and others that hold your computer hostage until you pay their ransom money. They tell you that your PC is infected with fake viruses, and prevent you from doing anything to remove them.

This particular virus goes by a lot of names, including XP Antispyware, Win 7 Antispyware, Win 7 Internet Security 2011, Win 7 Guard, Win 7 Security, Vista Internet Security 2011, and many, many others. It’s all the same virus, but renames itself depending on your system and which strain you get infected with.

The What Now?

If you aren’t familiar with this one, it’s time to take a look at the face of an awful scam. If you are infected, scroll down to the section where we explain how to remove it.

Once a PC is infected, it’ll display this very official-looking window, which pretends to scan your PC and find things that are infected, but of course, it’s all a lie.

The really crazy thing is that it pops up a very realistic looking Action Center window, but it’s actually the virus.

Removing Rogue Fake Antivirus Infections (General Guide)

There’s a couple of steps that you can generally follow to get rid of the majority of rogue antivirus infections, and actually most malware or spyware infections of any type. Here’s the quick steps:

  • Try to use the free, portable version of SUPERAntiSpyware to remove the viruses.
  • If that doesn’t work, reboot your PC into safe mode with networking (use F8 right before Windows starts to load)
  • Try to use the free, portable version of SUPERAntiSpyware to remove the viruses.
  • Reboot your PC and go back into safe mode with networking.
  • If that doesn’t work, and safe mode is blocked, try running ComboFix. Note that I’ve not yet had to resort to this, but some of our readers have.
  • Install MalwareBytes and run it, doing a full system scan.
  • Reboot your PC again, and run a full scan using your normal Antivirus application (we recommend Microsoft Security Essentials).
  • At this point your PC is usually clean.

Those are the rules that normally work. Note that there are some malware infections that not only block safe mode, but also prevent you from doing anything at all. We’ll cover those in another article soon, so make sure to subscribe to How-To Geek for updates (top of the page).

Removing Win 7 Anti-Spyware 2011

Download a free copy of MalwareBytes, copy it to a thumb drive, and then install it on the infected PC and run through a scan. You might have better luck doing this in Safe Mode.

image

You may have better luck installing MalwareBytes first, if the virus will let you. In my case, it did not. When I scanned through the first time using SUPERAntiSpyware, it detected the viruses and removed the files just fine.

image

At this point, you should hopefully have a clean system. Make sure to install Microsoft Security Essentials, and don’t be fooled by these viruses again.

Can’t Open Any Applications After Deleting the Virus?

The next problem was that once the virus was removed, you couldn’t open anything—in fact, I still wasn’t even able to install MalwareBytes. Hopefully you have better luck.

Why couldn’t I open anything? Because the virus had rewritten the registry to force all applications to open the virus instead—which meant you couldn’t even open the registry editor to fix the problem. This problem might have been avoided had I properly completed the scan, but I interrupted it before it was done.

On a normal PC, there’s a registry key under HKEY_CLASSES_ROOT that specifies what happens when you double-click on an executable file (*.exe) – but on a virus-infected system, this value is rewritten with the virus executable. That’s how it prevents you from opening anything.

image

To fix the problem, I exported a clean registry file from another PC, and did a little extra hacking to it, and problem solved! All you have to do is download, extract, copy the .reg file to the infected PC, and double-click it to add the information into the registry.
