MDM.exe was the moderately easy to get rid of, although it was disabled in IE8. Windows Installer has been another problem. In addition to the blinking, it has slowed down some programs and barely impaired others. Outlook, for example, is the worst for seeing the blinking. IE8 and Firefox are relatively normal. Restore worked once, but does not any longer.
These are the steps I have taken:
I went to Restore and went back several days. This did not help, At this time Restore wont respond to any prior restore point other than the current one.
I uninstalled RealPlayer and reinstalled. In trying to catch what might be missing, I also upgraded.
In searching for installers, I only found one which was for Microsoft Visual Basic or something like that.
I ran CCleaner.
I ran the new version of System Mechanic.
These two scans found a ton of registry problems which they seem to have cleared up, but not my Windows installer problem.
I ran Adaware -- five hours later it found 1 item.
I ran a complete AVG 9 scan. In five hours it found two Trojans in the startup and isolated them. A second scan during the night showed no infections.
The computer was restarted several times.
Today I have run Malwarebytes Anti-Malware which found two trojan.dropper infections. Removal did not clear problem.
Then I ran Hitman Pro 3 by SurfRight which found two tracking cookies.
I have gone through all services and don't recognize anything out of ordinary. Any further searching is probably beyond my knowledge.
I still have blinking dialogue box for windows installer and high usage of cpu. The only program that seems locked in Restore as I cannot access previous dates, only last one.
I don't know what kind of problem I have or what to do next.
Thanks for any suggestions.
