So what the F***, yesterday i updated Avast to version 8 and now flash videos or videos played in WMP not working at all!!! In youtube videos are green and in WMP just black, sound still works. Installed the patch from this site, it worked until pc reboot. Today i removed Avast and made clean install. All seemed to be working fine, until… PC reboot and now its the same, flash videos dont work on any site, Windows Media Player showing just black screen.
So WHY Avast 8 is causing this S*** on my Windows 7 64-bit machine??
And don’t suggest to turn Hardware Acceleration off !
