my computer window opens at startup

[illnessache]

hi to all of you, im having trouble with my pc, xp is the OS. at first i had some kind of virus, every time windows start it showed an error "windows can't find sembako.dgzjlh.exe" but then i ran avg antivirus and did this (HKEY_CURRENT_USER\software\microsoft\windows\curr entversion\Policies\Explorer\"NoFolderOptions" = "1", i changes the value from 0 to 1)and eliminated that problem, i also found out that it was some kind of virus that reproduces every single document into .exe, but with avg the problem was solve.
but then when i restarted my pc, another problem began, the window of "my computer" opens up immediately after windows starts up, ive tried solving the problem, by trying the "folder options > Restore previous folder windows at logon " thing, but nothing happened.
then i tried, run>regedit> HKLM_SOFTWARE_MICROSOFT_WINDOWS NT_WINLOGON_userinit, but there was no double "c:\windows\system32 ".
so could someone help me out? please
