I have downloaded and updated this program and I ran a scan. Nothing found. I am the admin of my own PC.
I tried to restore my pc on windows 7, and yes, the restore worked, but only for one day. When I tried to restore it again, then windows 7 changed a different restoring point time and now it doesn't work at all.
I still have same problem as before. I strongly suspect that it is not a virus, malware or anything else that caused the problem. I suspect that it is Microsoft own update that is making a mess on the scripts and in the registry editor database.
I opened Event Viewer and found many error messages, and I don't know which one to take. All problems started on 27 June when I did a lot of updates on windows 7. Some of the messages that I got are:
"Windows detected your registry file is still in use by other applications or services. The file will be unloaded now. The applications or services that hold your registry file may not function properly afterwards.
DETAIL -
1 user registry handles leaked from \Registry\User\S-1-5-21-4163880899-2263788322-3638369065-1000:

And
"{Registry Hive Recovered} Registry hive (file): '\SystemRoot\System32\Config\DEFAULT' was corrupted and it has been recovered. Some data might have been lost."
I also checked performance log, no problem there except that I deactivated UAC for a long time ago.
I have done everything. My drivers are there and everything else is working perfect and it seems that a bug on windows 7 is generated by their own updates. Unfortunately, I need to format this computer and do a clean install of windows 7.
