This is an unofficial response and the advice given is mine, not that of bleepingcomputer.com or it's representatives...
Did you recently install "Fraps.exe"?
Search your computer for "aff_50006.dll" (or "*_50006.dll") and upload it (if found) to "www.virustotal.com" and be sure to choose "reanalyze" when prompted, not view last report.
You should always get a second opinion on any malware alert.
Nod32/eset is a very good product, but I would recommend scanning with another (any other) product too.
Try SuperAntiSpyware or Malwarebytes Anti-Malware, or better yet, BOTH.
(you may need to adjust the default scan settings in SuperAntiSpyware, to get a thorough scan)
If 2 out of 3 products (or 3/3) tell you, you are infected... You are probably infected.
Once you have corroborating evidence for an infection, further steps will become clearer.
Just my personal opinion
