Same issue more than a day ago (after 13229). 97 computer has https problem, browser type doesn't matter. (all google site affected, many bank sites too, but the biggest problem: Office 365 e-mail server unreachable) Nod32 4.x ok, 5.x not ok. (bussiness versions) Every new update (until 13234) have a same issue.
Pre release or default update, doesn't matter ...
What we can do?
Pls help!
