With AVG Anti-spy at the end of the 30 day trial, certain extensions will be deactivated and the program will turn into a feature-limited freeware version. This can be used as a scanner and can be updated for new threats found. If you look at PP's instructions he specifically says;
-- Uncheck Resident Shield
-- Uncheck Automatic Updates
-- Uncheck Start with Windows
so if you followed the instructions above it WILL not be acting as a constant scanner or shield. I would keep the program, it should be updated manually to add new definitions before each scan. It does find and remove many Trojans, an anti-virus program does not generally protect against, locate or remove Trojans. Which you now have on the computer and some were found and all ready cleaned by AVG. Keep the program.

You are correct, too many programs running may actually lessen the protection BUT, first of all this generally refers to anti-virus programs and firewalls...and the rule is ONE of each on a computer. The spyware/malware scanner programs are just that, scanner programs, you should only use those for scanning the computer once a week OR when you notice a problem. You are NOT running multiple anti-virus programs, from what I can see in your logs you have ONE anti-virus program and that is the PC Tools Anti-virus, all the others you have run or are running are anti-malware/spyware programs, and no, you do not have too many. They don't look for, find or remove viruses.
I am still going through your logs and will get back to you asap.
