I e-mailed Avast as too many of are getting the popups. How do I disable my plugins to see if the popups stop.
III) If you get any URL malware warnings
If you get these virus warnings only when your web browser is open, it means that there's some plugin (add-on, extension) that's not malicious itself, but tries to connect to some infected website. Try to start the web browser without any plugin and check if the problem persists, please.
If all the above fails, there's probably some rootkit on the computer. The rootkit (
http://en.wikipedia.org/wiki/Rootkit) detection is heuristic (it's not using the known-bad signatures), it's based on a difference between 'the truth' and 'the lie' - any 'hidden' item (file, registry entry, process...) in your computer should be detected. Due this, some legitimate applications/services using this techniques (i.e. the 'virtual drives' are mostly the rootkits...) can be reported. Please verify the warning first - not every rootkit is dangerous and should be deleted - it's possible to use any rootkit scanner (i.e. Rootkit Revealer -
