A majority of the top antivirus providers offer a bootable recovery disk to disinfect your computer after an infected. These are essentially Linux-based software created to clean up the infected system that will not start up or cannot be checked by a regular antivirus software program running in Windows. To make it easier to use, I recommend the Kaspersky disk (though it will not work on some Dell systems).
Alternately, you can avail the same features from the Avira and ESET rescue disks which also come with a graphical user interface however, they require either a CD or USB device to start. Both options can detect and identify any malware on your system. However the virus definitions may not be regularly updated like the rescue disks based on Linux.
The Trend Micro Rescue Disk is another great choice. It’s also among the smallest disks on this list, at around 70MB. It doesn’t feature a graphical user interface, but it operates quickly and has a variety of options for customization, including the capability to mount and scan specific files, drive volumes and even specific folders.
You can also get an effective virus scan using the Comodo rescue disk, but it doesn’t have quite the flexibility of the alternatives based on Linux. It is however a very efficient tool for detecting and eliminating the kind of viruses that can hide themselves in Windows files in order to avoid detection by antivirus programs that are normally used. You can choose to use a text-only interface or a full-graphic interface. You can also perform a smart scan, or a custom scan.
