Give Viruses the Boot (Disk)
Some antivirus software will let you create a special boot disk. After creating a boot disk, you should reboot your computer with the disk in the drive. Your computer will read from the disk and load a limited OS and run a virus scan. With luck, this method will allow you to bypass the malware's code and disable it.
Advanced Computer Virus Removal Tips
If you can't access your antivirus software or you keep seeing the same malware pop up scan after scan, you may need to try and start your computer in Safe Mode. Many computer viruses will store files in your Windows registry folder. This folder acts like a database of instructions and tells your operating system important information about the programs you have on your computer. It can also tell viruses to activate as soon as the operating system loads. Starting your computer in Safe mode allows you to work with your machine using only the core elements of the Windows OS.
Try running your antivirus software in this mode. If you see new malware pop up, you may have hit upon your solution. Some malware exists only to download other kinds of malware and install them on your machine. If you can remove all of these applications, you'll be in good shape.
If for some reason your antivirus software can't remove the virus on its own, it's time to do a little more research. Remember when we said you should write down the names of all the malware applications that your software discovered? Here's where that comes into play. You'll need to research each of those files online using the appropriate Internet security firm. Make sure to use the same firm that produces the antivirus software you're using. That's because different firms sometimes give the same virus different names. Not all firms will refer to the same virus the same way.
Most Internet security firms will list all the files associated with a particular virus and tell you where you can expect to find those files. You may have to do some digging to find each file. Before you delete any files, you should save a backup copy of your Registry folder. If you accidentally delete the wrong file, you may make it difficult or impossible to run your computer properly.
Delete all the files associated with the malware on your list. Once that's done, you'll need to reboot your computer and run your antivirus software again. Hopefully nothing else will pop up.
You may want to update your login information for your various accounts online. Some malware has keylogging software that can send your passwords and information to a remote user. It's better to be safe than sorry.
