optispeed - keeps trying to install - not intentionally downloaded?

Hello.
Something called optispeed keeps trying to d/l itself onto my pc.
The only thing I have recently d/l has been mwb3 which has installed perfectly and is working fine.

I suspect optispeed was attached when viewing another site and was part of an advertisement.

That all being true I intend to delete it unless it is something to do with mwb3?

Thanks

Cheers dencal I'll give that a try.

Best
