I visited a website to find songs by Christine Lavin and clicked on 2 links to hear songs by her. Later I got a spybot warning that Smitfraud-C was attempting to change the registry. I denied this attempt. Seems to have been done through Quicktime. I looked at my wininet.dll, scanned it with both Norton AV and with Spybot--got negatives. Did full Norton AV and Spybot scans, which found nothing. But today there were 2 attempts by shdoclc.dll to connect to the internet, to, I think, "Adyield manager". I denied these also. Am I infected? Should I worry that I have a trojan that is not monitoring my online transactions, etc.? Tried to do online Kaspersky scan, but that is not now available. What to do?
