Malware is a frequent occurrence in the Windows world, and it can be devastating. When a Windows virus strikes, it can become difficult or even impossible to continue using the affected machine. Linux can be a life-saver without ever having to install the free alternative, you can still use it temporarily on a PC to get rid of any infection. Using a LiveCD or Live USB, you’ll boot the computer into Linux, completely bypassing Windows and its infection. Once the infection is found you’ll get the usual options for quarantine and removal.
