Many of the top antivirus providers offer a no-cost bootable recovery disk to disinfect your system after being infected. These are tools based on Linux that can be used to clean any computer that is infected by malware when it isn’t able to start or be scanned by an antivirus program that is running on Windows. To make it easier to use, I recommend the Kaspersky disk (though it’s not compatible with certain Dell systems).
You can also find similar features using the Avira or ESET rescue disks, which have an interface with a graphic design, but require the use of a USB/CD device to boot. Both options are able to analyze and detect malware on your PC, however their virus definitions aren’t updated as frequently as Linux-based rescue disks.
The Trend Micro Rescue Disk is another great choice. It’s also among the most compact disks on the list, with just 70MB. It doesn’t have a graphical interface, but it is fast and offers some options for customization. This includes the ability to mount specific files, drive volumes, and even individual folders.
You can also get a good virus scan from the Comodo rescue disk although it doesn’t have quite the flexibility of the Linux-based options mentioned above. It’s an extremely effective tool to detect and eliminate the kind of virus that may be hidden in Windows files, which prevents detection by antivirus software that is normally used. You can select to use a text-only interface or a full-graphic interface. You can also run a smart scan or a custom scan.
