Troj Arpoison.b

[Paran]

Okay, apparently I've been infected with a trojan called TROJ ARPOISON.B according to Trend Micro's real-time virus protection. The detection always pops up on the screen whenever I open an internet browser. The incident name is C:\Windows\system32\msqpdxxcrdxrei.dll but I've searched and searched but this file is no where to be found. At least to me.
Now, this trojan doesn't appear to be too harmful, but I could be wrong. It seems to take me to an entirely different webpage nearly every time I search google or click on a link. It mostly seems used advertising. I've tried various different virus and spyware scanners and none of them were able to pick it up. What should I do? Thanks in advance.
