looks like a dodgy site there. my search brings stereo mix plus as a paid bit of software, not the one here. Antiviruses and antimalwares are the way to go i think.
If all else fails, how long is it since you reinstalled windows? If its not been too long you could always try that again. Last resort mind you.
yeah i wasn't paying much attention was very tired when i d/l'd it and I ran malwarebytes nothing came up running avast now.
I reinstalled recent 2 days ago. only took 2 hours to do since i have service pack thing to install it quickly. So, if i must won't take long my computer is set up so my boot drive is very minimal.
kinda odd thinking that site shows up as the first one when i google for stereo mix plus.
would system restore point be useful option if avast fails?
