Many of the best antivirus providers offer a no-cost bootable recovery disk that can be used to clean your computer following an infection. These are Linux-based tools that can be used to clean a computer that has been infected with malware when it isn’t able to start up or can’t be scanned by an antivirus program that runs on Windows. For convenience I suggest the Kaspersky disk (though it won’t work on certain Dell systems).

Alternatively, you can get a similar range of features from the Avira and ESET rescue disks that have a graphical user interface but require an external CD or USB device to boot. Both options can search for and decipher any malware that is present on your computer. However their virus definitions might not be updated as frequently as the Linux-based Rescue Disks.

The Trend Micro rescue disk is a good alternative and one of the smallest of this list with a size of around 70MB. It doesn’t come with a graphic user interface but it does work quickly and provides a number of customization options including the capability to scan and mount specific drives, files and even individual folders.

The Comodo Rescue Disk is a great choice for a virus check, however it doesn’t 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 themselves in Windows files www.totalavantivirusreview.com/can-you-keep-track-of-business-expenses-in-vdr to thwart detection by standard antivirus programs. It is possible to choose a text-only interface or a full-graphic interface. You can also conduct a smart scan or a custom scan.
