This thread provides information on malware removal, links to malware removal tools, and recommendations & links to anti-virus software. The intention of this thread is to provide quick and accurate support for malware-related issues and questions.
Many people here are willing to provide assistance if you're having computer problems, and this thread is not meant to discourage people from asking for help.... but, please read the information provided first, or else there's a good chance you'll be sent here, here, or here . We aren't Geek Squad, so while we won't grossly overcharge you for information and advice, we also aren't responsible for anything you do to your computer.
Also, feel free to make suggestions on the content of this post, and I'll try to keep it up to date.
Research
A lot of information can be found at this EliteKiller link, including...
Step 3 unzip the Kit, read the instruction file and run the tools in the order given.
Step 4 Thank me in about 3 hours for fixing your shit.
The Rogue Removal Kit is is a zipped file that includes malwarebytes, CCleaner (a registry cleaner that will also delete temporary files), Combofix, Hitman Pro, and HiJackThis (HiJackThis is optional, see below). The instructions guide you through running these tools in Safe Mode With Networking; then running malwarebytes and an online scanner in Normal Mode.
Some people don't recommend running Combofix unless you're fairly certain you need to use it, but I've never heard of people having major problems with it. Here's a list of symptoms to Vundo infections, which may help determine if you need to run Combofix. You can also look here to see instructions with screenshots on how to use Combofix.
Taken from the readme in the Rogue Removal Kit:
Quality Online Virus Scanners: (all scanners offer detection and removal)
My two cents on downloading anti-malware software...
Download it from another computer if possible, or from Safe Mode With Networking on the infected machine.
Verify you are downloading from a legit source and are not being redirected to a site where you'll end up downloading more malware. If you click on any links above, verify the link in the bottom left before clicking on it, then after clicking the link verify that's where you were taken in the address bar.
The elitekiller article mentions downloading the software to a USB drive. Do not download the software to a USB drive on the infected machine if you're not in Safe Mode, or else you risk infecting the USB drive and other computers you connect the drive to in the future.
Other Helpful Tips & Tools
Rkill will kill processes that may be preventing scanners from completely removing malware.
To get into Safe Mode With Networking, press F8 every couple of seconds while the computer is starting (before the Windows splash screen). If you see the Windows splash screen, you will need to try again. The safe thing to do is log into Windows, restart, and try pressing F8 several times before seeing the Windows splash screen. Alternatively, my advice that falls into the category of “what I'd do if it was my own computer, but wouldn't tell someone to do it if I worked in tech support” would be, if you didn't get into Safe Mode the first time and you're at the Windows splash screen, hold down the power button until the computer turns off. When you start the computer again, it should automatically ask you if you want to go into Safe Mode With Networking.
Still infected, or just want to make sure everything is okay?
HiJackThis is a tool that will create a log file that can be analyzed by geeks to see what is running on your computer. Install and run HiJackThis (preferably in Safe Mode With Networking), and select 'Do a system scan and save a log file'. You can then copy/paste the output to this thread, and with any luck, someone will stop by and let you know what you can delete. You can then checkmark the items in HiJackThis and click 'Fixed checked'.
If you don't get a quick response here or would rather do it yourself, you can also go to http://hijackthis.de/, which is an online analyzer for your HiJackThis log. Simply copy and paste the log into the text box and click the Analyze button. During my testing of the site, I found it wasn't perfect, especially when a proxy was setup (the visitor rating would be 'extremely nasty', but the site itself would say it was safe)... but, it's at least a good tool that can significantly shorten the time it takes to analyze the log, and it gives you an idea of which entries you can delete or at least Google/post here for further research.
You can also look at the responses to HiJackThis posts in this thread to get an idea of what is safe and what should be removed.
Windows Performance
A good starting point to knowing what processes and services are running on your computer is a HiJackThis log. There's also a lot of information that's only a Google search away.
To manage the process that start when Windows starts, use msconfig (Start button -> Run... -> msconfig -> Startup tab). This is a good resource on startup processes, and it includes a large database of startup processes with information on whether they're required to run Windows or if it's okay to uncheck them. You basically want processes that are in c:\Windows checked, and you can generally uncheck processes in c:\program files (but there are exceptions, like your antivirus), but do some research (Google, the provided links, this thread) if you're not sure. Adobe, Apple (including qttask, Boujour, AppleUpdater, etc), and any messenger program (unless you have it sign you in at startup) are always the first ones to get unchecked on my computer.
Services can be a little tougher to manage, because it's usually a much longer list, and it's not as simple as flipping them on or off. This is a great resource for managing Windows services (Start button -> Run... -> services.msc). Simply choose your version of Windows and then click on the Service Configuration link. It presents the default setup, a safe setup (what most people can use without any consequences), a tweaked setup for faster startup, and a bare bones setup for the super geek. There's also a Tweaks page for stuff like Adding/Removing programs and System Restore. [Reply]

Post a hijack this log so we can take a look... [Reply]
This is my kids' laptop. Something shut off Avast. I think they had to select allow for that to happen because Avast doesn't let crap like that in.Also, several keys on the keyboard aren't working. [Reply]
You might want to run an error check on her hard drive, just to help rule out it causing your problems
Open Up "My Computer" and right click on the hard drive... choose properties. (it's usually the last choice)
You should see a new window popup with multiple tabs to click on, click on the Tools Tab.
Now you should see a button that says "Error Checking", click on it.
A new smaller window will popup, choose both options... auto check system errors and recover bad sectors. Now click start.
Depending on the size of her HD and the resources available, it might take a while. Start it before you go to bed and hopefully it'll be done by the time you wake.
The guys above have gave good advice, I thought this would help at least to see if the HD was causing problems. [Reply]
Ok, I have narrowed down that the keyboard issue is a bad keyboard. A USB keyboard works fine. I ordered a new one and it shouldn't be too difficult to replace.
But the whole thing with Avast is weird. It had some kind of malicious software that shut down Avast. Even after I ran everything according to this thread and got rid of the crap, Avast would not work. It won't work in safe mode, either. And I can't uninstall it and reinstall it. I'm using AVG now, but I prefer Avast.
BTW, I think the keyboard issue timing was just a coincidence. [Reply]

From the sounds of it, Avast imploded. I've seen it happen before, and it had nothing to do with any malicious software.
