Blt, have you contacted Symantec about this? Also, did you use a manual or automatic fix? And, did you update your anti-virus protection after removing Sircam?Nutty, I take it you have an up to date anti-virus program installed and running. You could try the AV company's support if you are getting problems that you feel may be due to a virus.
I am currently running PC-Cillin which was bundled with a motherboard I installed. Trend Micro, the makers of the software do offer a free on-line scan that you could try to see if it detects anything. The URL is http://housecall.antivirus.com/. Be warned that it is a long process on a slow connection.
