Got SpyBot, ran a scan in safe mode and found and removed 8 trojans

The past few weeks I been getting this on start up too

RunDLL
Error loading C:\Users\BigErn\AppData\Local\Temp\byXNeBrO.dll
The Specific module could not be found.


Whats it mean? How can I get rid of that?

Firefox has started crashing all the time too and I have to use IE.


I HATE COMPUTERS
