Windows 7,SP1
Safezone ver 1.51.2220.62
No VPN,no proxy
Avast IS, Malwarebytes Anti-Exploit,Zemana Antimalware
Safezone decided to be kind and opened pages yesterday (with all applications above working,so no clue why sometimes it works and sometimes does not), also there were like hundred of SZBrowser.exe processes in task manager.
I've found here at Russian subforum someone had similar problem, in his case Malwarebytes Antimalware was the culprit, he says, neither disabling nor uninstalling it helped, only reformat. So I guess maybe Zemana or Anti-exploit must have kind of the same conflict in my case? Why it was my first guess as both of them were installed later, and Safezone had been working fine initially.
Off topic, but now I have another headache with no sound in Avast Sandbox (Mozilla Firefox), I didn't find solution through forum search, the cases found had been resolved through fixing bugs in next versions, but I have just updated and repaired Avast. The sound works in an other browser without Sandbox
