I have been plagued by the AMD CPU and Avast issue since a hot fix and two patches ago. Others have been affected as well and not just those with my configuration. I submitted a trouble ticket. Twice. I got the most recent response:
The devs are working closely with Avast to resolve this issue as soon as possible. We invite you to contact Avast! directly to learn about the potential impact of disabling hardware virtualization. An update will be added to the thread as soon as we have more information that is concrete. We do not require any information from specific systems regarding this at this point however, thank you for the offer.
Now, according to some posters in the so named AMD CPU and Avast tread, it isn't limited to that configuration. In fact, there are some with that configuration who were not affected at all, without even using the two work-arounds players offered. So, I think the devs might want some other info from players.
With that in mind, respond to this thread if, and only if, you get the "Please Wait" after you press the "Play" button on the game launcher. To reiterate -- If you do not have this issue, please refrain from posting here. Again, PGI should know that even if they fix the AMD/Avast issue, there may still be some other configurations they have not considered.
What you should post is CPU, whether CPU is overclocked, mobo and mobo BIOS iteration, RAM (brand, quantity and speed), OS, what anti-virus you have resident, and any anti-spyware or anti-malware programs that are resident, and firewall (whether Microsoft's or something else, and MW:O version. If anybody else can come up with something reasonable to add to my list, please let me know.
