Removing stubborn infections
In most cases your security software should stop infections in their tracks, but if some creep through you may find them difficult to remove. Start by attempting to boot into Safe mode with networking – doing so usually cripples the malware enough to allow your security software to download the latest updates, perform a successful scan and remove the malware. The quickest way to do this is to type ‘msconfig’ into the Search box and click System Configuration. Assuming you’ve not been locked out by the malware, switch to the Boot tab to tick ‘Safe boot’ and select ‘Network’ before clicking OK and rebooting. If this doesn’t work, visit your security vendor’s home page on a clean machine to create a rescue disc – failing that, use Kaspersky’s tool ( https:// support.kaspersky.com/viruses/rescuedisk), which is free for all. Boot from this, thus bypassing Windows entirely, and you should have all the tools you need to search for and defeat any infections. After removing any infection, always perform multiple scans to verify all traces of it have gone – both before and after rebooting back into Windows proper.
