Many of the best antivirus providers provide a free bootable recovery disk to disinfect your computer following an infection. These are Linux-based software that can be used to cleanse a computer infected with malware if it won’t boot up or cannot be scanned by an antivirus program that runs on Windows. To make it easier to use I suggest the Kaspersky disk (though it won’t work with some Dell systems).
Alternatively, you can get the same features from the Avira and ESET rescue disks that include a user interface with graphics however, they require the use of a CD or USB device to start. Both of these options will analyze and detect any malware that may be present on your computer. However, their virus definitions may not be updated as frequently as Rescue Disks that are Linux-based.
The Trend Micro rescue disk is another option and one of the smallest on this list at around 70MB. It doesn’t have a graphical user interface, but it operates quickly and provides a number of options for customization, including the ability to scan and mount specific files, drive volumes and even specific folders.
The Comodo Rescue Disk is a viable option for a virus scan although it does not have the same flexibility as Linux-based options. However, it is an efficient tool for detecting and removing viruses that can hide in Windows files to prevent detection by normal antivirus programs. You can select to use an interface that is text-only or a full-graphical interface. You can also run a smart scan or a custom scan.
