Many of the best antivirus providers offer a free bootable recovery disk to disinfect your computer after an infected. These are tools based on Linux that can be used to cleanse a computer infected with malware, if it’s unable to boot up or cannot be scanned by an antivirus program that runs on Windows. To make it easier to use, I recommend the Kaspersky disk (though it’s not compatible with certain Dell systems).
Alternatively, you can get the same features from the Avira and ESET rescue disks which also come with a graphical user interface but require the use of a CD or USB device to start. Both options can analyze and detect any malware that is present on your computer. However, their virus definitions may not be updated as frequently as the Linux-based Rescue Disks.
The Trend Micro rescue disk is another great option and one of the smallest options on this list with a size of around 70MB. It does not come with an interface that is graphic, but it’s fast and comes with some customization options. It is able to mount specific files and drive volumes, and even individual folders.
The Comodo Rescue Disk is a viable option to run a virus scanner, although it does not have the same flexibility as the Linux-based options. It is nevertheless an efficient tool for detecting and removing the kind of viruses that can hide themselves in Windows files, preventing detection by normal antivirus programs. You can select between a either a text-only or a fully graphical interface, as well as the option to run a custom or smart scan.
