PC is Windows 7 Home version, 64-bit, and all current Microsoft apps are updated.
I have used the paid version of ESET for 3+ years now, and the license expires in 2+ weeks.
With this in mind, I tried downloading and installing the AVAST! free version this morning...all OK...did scan...all OK.
I then disabled ESET to start after rebooting, rebooted, and the PC just hung on the 'WELCOME' screen.
Tried rebooting again, same result.
I then tried starting in SAFE mode, and received 'audio' errors?? {and neither ESET or AVAST! started, and Microsoft Essentials didn't work, either}.
Tried again...same results.
I then decided to uninstall AVAST1 and use ESET again.
What's up?
