Safezone Browser too slow and won't work

Hello, I’ve got a problem, it takes really long time for SafeZone Browser to load pages, sometimes after 5-10 min waiting even not loading them at all. I’ve encountered this problem recently, it worked fine before, with regular speed. Could it be linked with installation of Malwarebytes Anti-Exploit and Zemana Antimalware,some conflict maybe? I already tried to restart Safezone Browser, updated Avast, restarted PC, disabled MBAE and ZAM, still it won’t work. Please, help, thanks

Repair Avast:

  1. Control Panel → Add/Remove programs → Avast
  2. Click on ‘Repair’.
  3. Follow instructions.
  4. Reboot.

Did that, still the same speed of a snail…

What happens if you disable Malwarebytes and Zemana ?

Nothing happens,same story

What OS/SP ?
What exact version of the SafeZone browser ?
Are you using a VPN/Proxy ?
What other applications are running ?

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
