hi
when im trying to open folders even "my computer"
i got this error

Link Removed - Invalid URL

i cant open any folders. but if i use browser or something and going to the downloads section and clicking one of the files "open folder" suddenly i got access to all computer. and also if im doing the same thing with other external apps
but normally true windows's 7 graphic interface i cant open any folder or uninstall something
but all things semms to pretty work. (playing songs, watching movies etc..)
and to solve this i must just restart the computer and it being solved for couple of hours and then it show up again somehow
i tried to make full scan using malwarebytes antimalware and nothing seems to be infected.
i also did sfc /scannow in cmd and i got this result

Beginning system scan.  This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.
Windows Resource Protection found corrupt files but was unable to fix some of th
em.
Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For example
C:\Windows\Logs\CBS\CBS.log

The system file repair changes will take effect after the next reboot.

maybe i need to do the scan in safe mode or something? or its not even related to the problem?
what da hell could it be?

Oh gosh, I am trying so hard to be diplomatic about this... Please don't be upset...

My friend... Did I not suggest you leave Windows default permissions alone?
This is the kind of thing you can expect...

I don't know if there's a fix for this, other than a clean install. A repair install might work... but in my experience it's not reliable.

not a big deal to make a clean install anyway.
i got win 7 only 3 days ago. lol
