If I restart Explorer this normally fixes the issue, and the fan stops.
I looked it up, and WRusr.dll looks like a Webroot process, but I can't find anything helpful.
Webroot isn't running a scan, and I've turned it all off, but WRusr.dll remains running. I assume then it's a shield or firewall of some sort.
Anyone know how to sort this out?
Also I just noticed it's doing the exact same thing on iexplore.exe (Skype plugin for business call I had today, that only seems to work in IE)
