It looks like you are keeping some things from running via msconfig
Some items which were set to run at start up have been disabled by going to Start, Run and typing msconfig.
System Configuration opens and then some items in the start tab have had the checkmarks removed from them so that they don't start up...we need to know what those items are.

Also looks like you installed a bogus codec and that is what is showing in your HJT and causing the problems.
This is a Trojan downloader on your computer. This probably came onto the computer without your knowledge. A Trojan Downloader may download adware, spyware or other malware from multiple servers or sources on the internet.
All three items noted by PP in his post were also noted in the Kaspersky scan as Trojans.
May I ask, did you run the AVG Anti-spy program in Safe Mode?
