Ok,
Leaving aside that Avast EPS does not yet work with Windows 10.
The free version does, so does Avast IS.
However I noticed that with Win 10 Home and Avast IS both the Win10 & Avast Firewalls were switched off. I cannot start the Avast Firewall but I can start the Win10 firewall.
What I did notice was that after scheduling a BootTime scan and restarting the laptop Win10 reported an App called Elara was preventing the shutdown.
It appears that many people are reporting this as a possible virus. More worrying is that MS Tech Support seem to know nothing about this App and suggest the user must have installed it.
Nope I didn't I actually deleted lots of crap the Win10 installed.
So is Elara a virus or PUP or just crap left behind by something ?
The PC running Win10 and the Avast free (instead of the paid for EPS) does not report this issue.
Nor have I had issues with the firewall.
