My daughter's computer had some viruses/trojans, i did a complete scan with norton security 2010 and found 9. When it was done the scan it said "winlogon.exe was found and deleted, please restart your computer" So I did, and now cannot logon to the computer. Will logon then logoff. Anything I can do? Safe mode? I don't want her to use our laptop because she seems to pick up viruses from somewhere.
