|Download and burn to DVD an ISO of Kaspersky rescue disk.|
Boot up with that.
It will boot into a Linux based desktop; and go online to update itself. Then will scan your HD fully... and remove anything nasty it finds.
The OS (a Linux variant) will load into RAM only; thus leaving the HD as mere resource for the RAM installed OS - which it can will scan and clean.
Afterwards.. boot into Windows as per norm; and then download and run JRT (Junkware Removal Tool):
JRT will install itself to e the Desktop and produce an icon there. Click on that icon to open a dos style window. Follow the onscreen prompts. As I recall it will require a reboot to complete its work.
Both of the above are freebies; and and safe to run.
There are pests that can insinuate themselves into the OS and effectively hide from many anti-viurs utils; if the OS is actually booted up/active. Scanning from outside the affected OS itself means they can often (usually) be defeated... The Kaspersky disk is one of several that can do this. JRT goes after other pests that may lurk in other ways - within the booted/active OS...; and useful to run after the Kaspersky utility.
