Thank you.

AVG Driver Updater recommended I update several drivers yesterday.
I followed this advice, and tried to update I/O LPC controller, which Driver Updater said was out of date.
Once this driver was updated, I could not navigate to any internet site with either Chrome or Edge. Only AVG's Secure Browser seems to be able to work (and it is what I'm using now in order to access this support page).

On Chrome (or Edge), uf I try to go to a site all I get is a message like:

The connection for this site is not secure

www.google.com sent an invalid response.

 


ERR_SSL_PROTOCOL_ERROR

Does anyone have any ideas about this?

Many thanks!
