Going on 6 months of downtime...
Ever since the compromise, this has been a problem. It doesn't take 6 months to build in function to re-key certs... This is absolutely horrible, Avast has truly ruined CCleaner... Stop wasting time and hire an outside firm of professionals that can fix this for you in a matter of days, not months / years... This is the kinda of stuff my company does and can help you with! Stop the bleeding, your reputation is on the line and your are losing money every single day from this...
