But one day I notice that the “Auto Protect” icon at the tray was gone.(its enable) Tried open it by the Start menu programs…but not loaded. Uninstalled it. Deleted C:\Program Files\Symantec C:\Program Files\Norton C:\Program Files\Common Files\Symantec Shared C:\Documents and Settings\Administrator\Application Data\Symantec Then I tried installing Norton Antivirus 2003 Pro. Got it from my 2nd pc mobo cd. Installed, Restart, When I’m in windows the icon was there but as soon my mouse cursur to it….,its gone… Checked with the "Services and Application" in the Computer Management the "Norton AntiVirus Auto Protect Service" is not "Started" tried to start it but after about 10 seconds it "stops" by itself. Oh yeah btw i used the Norton Removal tool from Symantec website. stil... duh not working sigh…*** I plug my hdd in to a working pc with updated virus defination. Did a full scan and no virus was detected. I even used IE to go to Symantec’s website to do an online scan, no virus or Trojan was found. Run the Klez,Bugbear removal tool….no virus found. Followed the help files at Syamantec still not working. Have anyone ever did encounter such problem? How did you solve it besides the best way that is “format and install again” Please help me…..
