Probably the first thing I would do is stop using IMesh. I find that Shareaza is quite good but there are lots of download agents. Then I would download Ad-Aware from
www.lavasoftusa.com and remove the spyware that IMesh has most probably unleashed on your computer. If you are hellbent on using IMesh then I would at least suggest getting some form of spyware removal tool to clean up you computer. Also I would try re-installing IMesh as well but as I said, this is only if you are dead set keen on using it. There are much better programs out there that do a better job.
