PC's was playing up massively but nothing was being picked up, did a deep scan with virgin media secuity and found nearly 4000 infected files, inc a load of trojans and backdoor.trojans. have removed all of these, ran spybot and malware bytes and found a few more infected and remvoved. seems to have corrupted office. I still have searchsettings.exe which everywhere i have looked has come up as malware, but none of the three security programs can find it. Can't just delete the file. Anyone got any ideas of how to remove it.
