Problem when turning off computer

Hello:

I've some issues with my computer, sometimes it takes a lot to turn off, there are sometimes that takes too much to start a new application or installing one... One of the most annoying issues it has is when I want to delete a file, it takes minutes to delete it, and the file is just a few KB of size... There are other issues that it has been suffering... I remember that I used a software to unlock windows registry or something like that a while ago... Maybe that's the root of the problem, the only thing I can say is that Antivirus haven't successfully solved the problem. I used Kaspersky and I attached the report. Any help is welcome!

Switch off/Disable:
- Antivirus and and, if you have - Firewall.
- System Restore

AVPTool should be started 'as adminstrator'
