Adware.gen

I have just run a full virus scan and NIS has come up with a low risk heuristic threat called adware.gen - I ran the full scan a couple of weeks ago and this threat did not appear then.

 

I have Lavasoft Ad-aware Anniversary Edition running on my pc is it anything to do with that?

 

The report says 53 registry entries,1 file and 1 browser cache are affected

 

The file concerned is C:/i386.gtdownde-87.ocx.

 

I run a Dell with XP on it and I think its NIS2007 running on it.

 

Can I just click on fix or should I ignore?
