Like I said, it’s an audio driver file. Unless you’re having audio problems I wouldn’t sweat it. And, if you do find audio problems down the road, you can always install/reinstall drivers to remedy the problem.
Check Device Manager and see if you have any “bangs” [exclamation point or question mark] on any devices. If you don’t, then don’t worry about it.
Your other option is to do a system restore to a day BEFORE the Avast support guy was into your computer. But don’t do that if you don’t have any bangs in Device Manager! You’ll just make more work for yourself than is necessary.
I don’t understand what you mean by “Safe Zone on the computer you’re connecting to”. Is that the firewall you’re referring to? What computer is it on? If it’s on yours, I would get rid of it. It has lousy reviews on C|Net’s download.com. All you need on a W7-64 machine is Avast, Malwarebytes (free version), SuperAntiSpyware (free version), and a router with NAT and SPI (and safe-surfing habits, of course!)
