I recently got some software called "Second Thought" or something. I'm not sure because I deleted everything. I went to Regedit and removed all of the stuff. Basically, my antivirus program, PC-Cillin, identified it as STC, a virus. Then, it quarantined it and I removed it. However, my PC is now acting weird. PC-Cillin's web trap thing keeps popping up and I am still told I have the virus. It's been a bit less than an hour. I did nothing to cause this. How do I get rid of this thing?
