i got a trojan virus on my computer, i downloaded a program called PREVX
it scanned my full system and got rid of it!
i got a subscription for 1 month free
and the paid something like £2 for 3 months after that
or you could get it for a year for £9
it does not clash with any other anti-virus software either and regularly scans for bad files
thats what i would recommend
