For whatever reasons, games that run using Unity, such as Gone Home, do not work with Avast, which I find quite the problem, I don’t know if it’s well known but I wanted to bring it up.
Then I guess that means it isn’t compatible with Avast then, or it does not compat on your PC.
It’s a lot to go into and I couldn’t explain it all properly but just google “Avast and Unity” and you will find a tons of issues with Unity Web Player and Avast not playing well together.
Okay, good to know. 
Is this a known issue?
Could you please specify your problem, OS and avast version?
Any game that runs Unity will not launch, it will start but never actually get to the game, just a black screen with a the spinning busy symbol in Windows 7.
My avast version is 2014.9.2018
The issue isn’t mine alone, it’s a very well known problem with Avast on games that run using Unity. It’s a serious issue that has gone on for over a year and has still not been addressed.
I can’t reproduce it, could you please give me some links to games you tried?
thank you
Gone Home I believe is the biggest offender.
I have disabled Hardware Virtualization and it seems to work fine now, since I don’t use any sandbox or screenclear features, is there any real risk with leaving this disabled?
Anyone know?
There is no risk, if you don’t use sandbox.
What kind of video card do you have?
Unfortunately I can’t reproduce your problem, it works for me with avast, with both disabled and enabled hw virtualization.
I have a Nvidia Geforce GTX 750, it works just fine with it disabled but the game refuses to boot past a black screen when it’s enabled.
The hardware virtualization helps other things in avast! as well - e.g. it strengthens the self-defense on 64bit OSes.
Ah, so I should reenable it as soon as I can then?
Is it enough of an issue to make it a terrible idea to have it disabled?
No feedback on this, how exactly does it make it more secure?
Anyone care to elaborate?
Well, it does make the self-defense more secure, i.e. it prevents a number of known attacks that active malware (should you get infected) can use to kill the antivirus (and which cannot be prevented without the hardware virtualization).
If you need to have it disabled to run some programs… well that’s probably the best you can do (it’s not like disabling it would cripple the antivirus completely). But yes, the hardware virtualization makes you a bit more secure.
Thank you igor, it’s something I want to be as secure as possible without sacrificing usability, I’ve had it disabled for awhile now without any issues, although I did one time get careless online and hit a trojan, thankfully Avast still detected and stopped it, so I’m thinking it still is functioning well enough as an Antivirus without it.
So correct me if I’m wrong Virtualization, just creates a way to prevent the Malware from disabling the Antivirus. Any signs to look for to see if Avast has ever been compromised?
