Yep, good product except for this one really annoying issue. We used to have workstations perform a scheduled scan every day during work hours since there was no easy way to wake the computer from sleep to perform the scan during the evening. However, we can't do that now because it will interfere with the user. They would be working during the scan and shortly thereafter, they would no longer be able to browse the internet or perform other processes that require DNS (even email was affected). Asking users to reboot their computer whenever this happened was not an option. From scanning other posts on this forum, I see absolutely no solution from MWB other then to request for debugging logs - so I eventually gave up on this one. I think the best action is to simply not perform scheduled scans. Just do them manually if you suspect anything strange and then reboot. At least enabling MWB full security in combination with Windows 10 Security Center (ie. MWB provisioned so as to not replace Microsoft Security Center) seems to be the best option for a combined protection blanket)

Both

That was our situation. Seems to be an issue with the scanning. Of course a reboot helps but that sort of defeats the purpose of scanning in the middle of the evening when you want to keep the WS. Our final solution - don't schedule scans unless you can reboot afterwards.. Only perform them manually when you suspect some issue and then reboot. Between MB and Windows 10 Security Center, we feel our workstations are pretty well protected either way.

Good point. Thanks

I suppose with all the MB protection settings enabled there would be less need to run a manual scan in the first place (unless one suspects some type of malware). So together with Windows 10 Security doing its thing (which does include periodic scanning without interfering with Internet access) – this might be the best possible solution at this time.

No doubt that will work...

Yes, just tested (again) now. All I had to do was run a scan, wait for it to complete and “bingo” – slow internet access again. Firefox was a problem here as well. Instead of rebooting my laptop to get things going again, I just disabled all the MB protection services and closed out the program form the task-bar link. Problem resolved.

Same problem here. Running Windows 10 Pro – Latest updates and MalwareBytes Premium (latest released edition). Windows 10 Security center is the only other active product enables. This has been going on for weeks and is extremely frustrating. Initially, I thought this was related to the Web Protection but I turned it off and the problem persists. It usually occurs after a scan and only a reboot or killing the MB service resolves. The issue appears to occur across Edge, Chrome and (in my case) effects other internet communication services like launching Outlook, establishing VPN connections etc. I am sure this has nothing to do the our network connection as – when this situation occur- I can spin up a VM on the same computer running a clean Windows 10 and (within that VM) – I see no problems navigating the internet – of course the VM does not have MalwareBytes installed..
