Recently when I browsed to E:\My Documents\My Music Folder it was empty. All 300+MB Songs were deleted permanently. BTW my PC Config: Intel P4-2.4Ghz, 256MB RAM, 80GB HDD, Intel 845Mobo with Windows XP Pro SP2. Now I don't want to recover my songs. I have tried it already. System Restore does not help in this case. I want to ask you how is it possible? Because some songs were left and I copied them again to E:\My Documents\My Music to test and again they got deleted automatically after 1 day. To tell you Nobody except me operates the PC. Also I have moved My Documents folder to E:\My Documents\My Music as my official My Documents Folder. Also along with the songs many other files including a folder related to my college containg all files, project report were deleted. thankfully I had its backup. How is this possible? Is it a virus? Also now to figh back I got the latest McAfee VirusScan 10.0 and also have IE 7.0 Beta. When I want to update the McAfee it opens IE window and shows Why it detects IE as Netscape? Also downloding Plugin does not help in Firefox as it shows in Firefox that cookies are not enabled which are enabled actually. Also files 4584xdat.exe and sdat4584.exe to update McAfee does not update it. Why? Should I download some other file to update it. I think I will have to revert to IE 6 SP1 as Yahoo! is not compatible with IE 7 beta either. Though IE 7 beta is a good nice browser. Bye and Please help me. Navjot Singh.
