web agent

Since yesterday and the suppresion on chrome (i work with vista) of the extension avast safe price the web agent is blocking or slowing strongly the access to some sites incuding my professional web address without any reasons.
I have tried to repair twice avast (change of the driver etc…) without success, restored 24 hours before cause i thought it was this supression that had caused the problem, removed avast with the prospect of downloading again and each time same blockage. Everything is back to normal when i put off the web agent.
I have never had this problem before.
Would this come from the last avast update.

Disable https scanning in the webshield and let us know if it solved the problem or not.

Is it something i do in the exclusions?

it’s done i am going to check then

It seems to work thanks but is it not risky to desactivate this scanning?
