When my computer turns on a box pops up that says "C:\Windows\system32\hjxuqqka.dll The specific module could not be found". I heard it has something to do with a trojan virus but Avira antivir on my PC does not detect anything and my spyware program doesn't detect anything.
What should I do? :confused:

If this is from a virus that may have been removed already by your AV software, this may be a remnant in your startup configuration from the original infestation.
START > RUN > msconfig
STARTUP tab
Go through this list of things that have check mark and see if you can spot the item that might be related to hjxuqqka.dll and UNCHECK it.
Reboot
Any better?
