SpyBot, Malwarebytes Anti-Malware Won't Run

I recently visited the pearldrummersforum website and noticed a warning indicating "This website may be harmful to your computer", but I went ahead to the site anyway. After this I noticed that my computer ran slower and things took longer to open in my browser window. I attempted to run various programs that I typically use to detect and remove spyware, including SpyBot Search and Destroy, Malwarebytes' Anti-Malware, Norton Antivirus and others. When I tried to run SpyBot and Anti-Malware, they would not run. The hour glass popped up for a second and then disappeared. After some Google searching, I found suggestions to rename the executables and try again. This worked in both cases. I let both programs run and they both found several things, but after allowing them to remove what they found I still could not run either program using the original name. I uninstalled and reinstalled a few times. I've also run Norton Anti-Virus, which found nothing, and did a scan using Panda Security ActiveScan, which still reports problems. I thought I would try asking for help before re-imaging my machine.

I've attached my HJT log and uninstall list.
Thanks very much,
Steve
