The threat log shows Nod32 is cleaning the infected files(all .exe files) but its not finding the file thats causing the infection. It seems to be coming back on every even date of the month(14th, 16th and today 18th). Google wasnt much help with removal instructions or any other information but I tried sophos antirootkit and it doesnt detect anything. Still every other day the infection is back. Everytime nod32 updates it starts scanning and cleaning all over again. Don't want to format my windows drive bcoz I dont even know which partition the infecting file is on. Need help here asap. How do I proceed from here?
