Also, every time time i start the computer now (since i tried to remove the virus by myself) this message comes up.

Error loading C: /windows/system32/tutqyjjd.dll The specified module could not be found.

Also, the welcome screen to windows xp takes a little while longer to load now? any reason why?

The "Cannot find...", "Could not run..." or "Error loading..." message is usually related to malware that was set to run at startup but has been deleted. Windows is trying to load this file but cannot locate it since the file was mostly likely removed during an anti-virus or anti-malware scan. However, an associated orphaned registry entry remains and is telling Windows to load the file when you boot up. Since the file no longer exists, Windows will display an error message. You need to remove this registry entry so Windows stops searching for the file when it loads.

To resolve this, download Autoruns, search for the related entry and then delete it.
  • Create a new folder on your hard drive called AutoRuns (C:\AutoRuns) and extract (unzip) the file there. (click here if your not sure how to do this.)
  • Open the folder and double-click on autoruns.exe to launch it.
  • Please be patient as it scans and populates the entries.
  • When done scanning, it will say Ready at the bottom.
  • Scroll through the list and look for a startup entry related to the file(s) in the error message.
  • Right-click on the entry and choose delete.
  • Reboot your computer and see if the startup error returns.
