Can only open windows in safe mode

I'm not sure why you haven't been asked to run a full AV and Malwarebytes scan. Did I miss it?

Since you have 32 bit you get the deepest scan of all if you schedule an Avast Boot Time scan. Do that now.
Otherwise download and burn to CD Windows Defender Offline to to a boot scan.

Once you clean up infection run again SFC /SCANNOW Command to check once more for damage.

If you feel establishing a Clean Boot solved the issue then a program is interfering. Just because you've turned it off at startup when it isn't needed doesn't mean it won't foul your install again if you run it. So I'd check the logs, System Resources and examine what was starting with Windows from the steps in Troubleshooting Steps for Windows 7 to try to find the cause or gather clues.

thx for help, i try do all the things what u telling :)

hmm. avast still wont work after rebooting, it says access denied when try shutdown from taskmgr or try enable it from services.
maybe i need change my av then
edit: did run all scans expect avast (because not working)
also did run sfc scannow and it didnt find any errors.
but guyss i go sleep now :)

If Malwarebytes won't Update and run a Full Scan in Safe Mode with Netowrking, I would move into the boot mode to run Windows Defender Offline from CD or flash stick.

Then using the Win7 DVD or Repair CD run SFC /SCANNOW Run in Command Prompt at Boot

malwarebytes worked fine and did full scan with it.
removed some old malwares (i think they are false positives) nothing else.
and removed some things with kaspersky tdskiller + adwclean too

edit: i check ur links tomorrow if problems continue.

thx guys for helping i mark this as solved now bb :)

Did you check System Files again after the virus cleanup? SFC /SCANNOW Command

How is performance now?
