Hi guys, i don't know whether you had this problem or not. But i am really p***ed off with this, actually i have a 160 GB SATA USB hard drive (laptop) . I have 4 drives. and since i have installed Vista(i didn't notice in XP) there are some files automaticallly created in all the USB drives. and as soon as i double click the drive it opens up in another window not in the same window. 1.I have formatted the Drives and deleted the files and folders, I don't know how many times.. 2.ran a virus scan for the whole Hard drive. (symantec Coporate) 3.ran spyware scan as well.. tried everything.. (built In Defender) the files and folders are as follows: folder $lcldata$ folder msrm folder NT.Config file AAUTORUN.INF file inform.exe file idupver.txt and all these are system files. attached is the screenshot of one of the drives. i have also opened the autorun.inf file at top. Thanks Kuld33p
