Initially there were Brontok, sal.xls.exe and the like.. I was really pissed off by them.. but then when i got in touch with more geek guys, i got solutions for them..
Recently I had a one-on-one with System.exe... It's a virus tht was residing in my pen drive and i was unaware of it. (I hate giving my pen drive to ppl) . When I inserted it into my XP Laptop, it started screwing me.. i figured out something's wrong coz the mouse piointer started behaving ITCHY and STICKY.... AS expected, when i clicked my drives, it showd the "Open With..." dialog box... TWO full scans with Avast and Antivir... but in vain! Finally i tried to open Taskmanager... i saw two processes system.exe and sys.exe ... i thought them to be the culprit and tried to end it but suddenly task manager closed... it never opened again. then I tried to unhide all folders thru DOS and there i could see the devil himself.... A SYSTEM.EXE . i thot i will delete it and al probs will be gone. but when i deleted it... my system restarted... then somehow.. avast caught it and shred it successfully... two days of tension gone..
