Today, Avast seems to have decided that Facebook is bad juju -- if you visit the site in any browser, with out without the Avast plug-in enabled, the computer starts thrashing; Task Manager reveals that AvastSvc is using some ridiculous percentage of CPU; meanwhile, the internet connection is dropped; no other sites may be visited and all desktop applications complain that they have lost connection to whatever it is they're supposed to be talking to. Killing the browser task does nothing to remedy the situation; finally, the computer has to be rebooted.
Adding "https://www.facebook.com" to the Avast Web Shield's exclusion list gets around the problem. So now I have to go around to all my users and do this.
It should be impossible for Avast to thrash so heavily that no other process can run: meanwhile, this is a Skylake processor with 64 Gb of RAM.
Please fix the thing.

It's not just facebook - it's an issue with the "webshield" piece blocking DNS. There are existing threads on this.

Same problem noted here, but only with facebook thus far

Dan, thanks for reporting this. We have already found a problem and your observation that is happening while visiting Facebook helped us verify that we are looking at the right place. One of the patterns in the virus database was causing an endless loop and that is also the reason for high CPU usage during it.
The fixed VPS (virus database) is just being compiled and should be released in a couple of hours. Thank you for your patience and sorry for the troubles this has caused!

Update, reboot and your problem should be solved. :)

Still issues going on and not just Facebook as other poster mentioned, still having issues please advise?!
I answered one your other posts (please stick to one report and don't post in multiple topics), try a manual VPS update, I have just done that and it brought in VPS version 181113-13.
