krom is correct. I had the dlder.exe trojan packaged with kazaa. I am not smart enough to understand all the implications of this trojan, but the explore/explorer.exe file (hidden) that it sets up is not so easy to get out, at least is was not for me.
I have since installed zone alarm pro and I am amazed at the number of sites trying to "hit" my computer!!!
Servers and providers I have never heard of.
Once again, my lack of knowledge of these trojans is tremendous, but I am certainly more cautious than I was 3 days ago.
FYI, the trojan was called spin tilluwin. (this may not be the exact spelling_.
By the way, how does one "complain" about something like this?
