As far as I can tell your computer is clean at this point. I wanted to see the avast! log to make sure nothing was occurring significantly later than the first ComboFix run since that cleaned most of the problem files. Even though there is one file slightly after that I do not see any indication that a downloader is still at work.
Open OTMoveIt again and click the Clean Up button. This will remove the tools we downloaded and the malware backups.
Next, we will get rid of any remaining, possibly infected restore points and create a clean restore point:
Click Start > All Programs > Accessories > System Tools > System Restore. Fill the radio button to Create a Restore Point and click Next. Give the new restore point a name you will recognize if you need to find it (like Clean Point) and click Create.
Now, click Start > All Programs > Accessories > System Tools > Disk Cleanup. Now click the More Options tab, then click Clean Up in the System Restore section and OK.
After that finishes open Internet Explorer and click Tools>Internet Options>Privacy>Advanced. Make sure the option to reject third party cookies is checked (you may need to check Override Automatic Cookie Handling first). Then click OK>OK. This may help with some of the cookies you've been getting.
Finally, you should consider installing a third party firewall. Comodo is my favorite but Zone Alarm and PC Tools Firewall are also good (all 3 are free)
http://filehippo.com/download_comodo/Keep SuperAntiSpyware and AVG Antispyware on your computer and scan with them from time to time. This will help keep you clean. Spyware Blaster is also a good, passive defense against malware
