Right loosing administrative rights to those (2) areas indicates a virus may still be present, even though the pop ups are gone this is common with certain virus what it does is changes the windows registry an places restrictions on these 2 items. Your best bet as suggested is to go to a spyware forum & post a hijack this log, in that log you will more then likely see the 2 (06) entries that confirm the restrictions---no need to reinstall the operating system for this.

Don't clean up to much! When in doubt don't do anything. I have seen a lot of problems when cleaning up too much. Leave all those programs listed there as is. The only thing you need to do is run TFC, CCleaner, ATF. Then do a defrag. Then check out what's starting up with windows and get a hold of the unnecessary start ups. Startuplite is a good program to use for that from Malwarebytes. Once the computer is running good , flush out the System Restore points by turning system restore off and back on. This will free up space and clear out any possible bad restore points. Here is a link that might be useful: Start up lite

D, Not to over promote or beat REVO to death I have a current example of its service. I just removed WinAmp Full with REVO in readiness to install a current version. WinAmp is a long time and reputable application so a user could assume it had a capable on-board uninstaller. As suggested above, I selected Advanced mode and then engaged REVO. After the on-board uninstaller finished REVO took over. It located 4300 orphaned registry entries, and 1400 orphaned files and folders. These are REVO's numbers not mine. All entries were easily removed. There is the worth of REVO. DA
