I need help getting rid of this virus/malware/rogue. It's ruining my life.ok a couple of questions to get a clearer IDEA of the problem

do you have anti-virus software installed?
if so what program?
is it up to date?
when does this message appear, on STARTUP (GUI) or on trying to access a specific file?
does this appear when you boot into safe mode in windows? (if not use msconfig or windows defenders "software explorer" to disable 3rd party applications from STARTING at system boot and re-enable one at a time until you encounter this error again).
ALTERNATIVELY if you know what program this error is referring to try to repair the installation to see if that does anything OR un-install then re-install the program.

try malwarebytes anti-malware OR spybot search & destroy to scan for malware etc. See if they find anything. If you need anti-virus there are plenty of programs out there (free and subscription). I'm no security expert but i don't think there's much of a DIFFERENCE between the free one(s) and pay-for-use anti-virus programs.that sounds really familiar. sounds like "internet Security 2010" infections. its a tricky one but running combofix can really give you a good start. here is a tutorial on how to use it

maybe after thats done i suggest a malwarebytes scan with eset online scan. keep posting
