Your screenshot says nothing about certificate expiration?

It does bottom right of the screenshot, but it is a very big screenshot.

hi again

i had latest version, cause i uninstalled and reinstalled few time, donno why the icon didnt change on the blocking stuff , but main icon was the new logo

anyway, i disabled av, i tested few browsers, and all had some error. soo my apologize
i had done a antivirus check in safe mode(other antivirus), avast didnt wanted to run in safe mode.

+ fresh OS +avast installed  and all is ok

so in the end the issue was not antivirus, i think my OS had some problems  but i dont explain why..

mark this as solved!
thank again for quick support! definately i will stick using avast  now and in the future

I had this same problem (see attached).  I really didn't feel like reinstalling Windows, so I decided to try using avastclear and doing a clean install (I deleted the Avast folder in ProgramData too just to be sure).  I figured that since the old Avast logo was appearing, it might be a zombie component or something like that, and I guess I was right, because it worked.
