Many of the best antivirus providers offer a free bootable recovery disk that can be used to clean your computer following an infection. These are basically Linux-based tools created to clean up an infected computer that doesn’t start up or isn’t examined by a standard antivirus software running in Windows. I suggest the Kaspersky disc for its ease of use (though it might not work on some Dell systems).
If you prefer, you can pick up a similar range of features from the Avira and ESET rescue disks which also have a graphical user interface but require a CD or USB device to start. Both of these options will analyze and detect malware on your computer, but their virus definitions aren’t updated as regularly as the Linux-based rescue disks.
The Trend Micro rescue disk is a good alternative and one of the smallest options on this list at just 70MB. It doesn’t have a graphical interface, but it’s fast and comes with some options for customization. It is able to mount specific files and drive volumes, or even specific folders.
The Comodo Rescue Disk is a great choice for a virus check, although it does not have the same flexibility as Linux-based options. It is however a very effective tool for detecting and removing the kind of viruses that can hide in Windows files, preventing detection by antivirus programs that are normally used. You can Read Full Report choose to use either a text-only or full-graphical interface. You can also perform a smart scan, or a custom scan.
