A lot of top antivirus providers offer a no-cost bootable recovery disk to disinfect your computer after it has been infected. These are tools based on Linux that can be used to cleanse any computer that is infected by malware if it’s not able to start up or can’t be scanned by a standard antivirus program running on Windows. To make it easier to use, I recommend the Kaspersky disk (though it’s not compatible with some Dell systems).

You can also find similar features on the Avira or ESET rescue disks. They have an interactive interface, but require an external USB or CD drive to start. Both of these options will analyze and detect any malware that is present on your computer. However their virus definitions may not be regularly updated like the Rescue Disks that are Linux-based.

The see here now Trend Micro Rescue Disk is a great alternative. It’s also among the slimmest disks on this list, at about 70MB. It does not have an interface with graphics, but it’s fast and comes with various options for customization. It is able to mount specific files, drive volumes, and even individual folders.

Finally, you can get an effective virus scan using the Comodo rescue disk even though it’s not as flexibility of the Linux-based options above. It is however a very efficient tool for detecting and removing viruses that hide in Windows files to prevent detection by normal antivirus programs. You can select between a an all-text or full-graphic interface as well as the option to run an intelligent or custom scan.
