Recently four computers in my office (3 XP SP2 and 1 Vista SP1) are affected
by virus win32.sillyFDC. Although the virus is detected and deleted by Norton
anti-virus, something is wrong with all our computers. Here are the symptons:
1 The adiministration tools (event viewer, services, computer management
etc.) in control panel can't be opened. The error messages is
"C:\WINDOWS\system32\eventvwr.msc, access denied".
2 Run gpedit.msc and get "access denied" error. But it works under command
prompt: C:\>mmc %SystemRoot%\system32\gpedit.msc.
3 System restore is disabled by group policy.
4 Remote desktop no loner works.
Any help will be greatly appreciated!
