Problem with Avast free AV

there an error with updating to march patch… at first i thought it was my connection so i checked it but it had no problem… so i went on to repair avast in control panel, yet problem is still there…

so i tried re-install it but after uninstalling i cant install it back because of some error as attached…

any advice is appreciated or one-off program that can scan and clear any related problem is good

Something to try, change dns to Google or OpenDNS and try again

Any change?

done that…

also done manual uninstall from control panel, reboot, run avastclear, reboot again
