Hello Avast,
I couldn't find anywhere on your site Avast.com to post this so I thought I'd do it here. Just wanted to say thanks a bazillion for this awesome product. I've always thought Avast was pretty cool but today you guys just upped the ante. I was having issues installing a program on my PC, the program would freeze my PC when doing the install forcing me to do a hard reboot. I gave up on uninstalling the program but then found out that none of my games in Steam would start! After much checking of drivers and setting on Win 10 I was still unable to resolve the problem, eventually I started thinking that perhaps I should try and do a registry clean up. So off I went on an internet search for free registry cleaning software. Pretty soon it became apparent to me that I was walking into a minefield, I mean, who do you trust? Then, I remembered that Avast does a performance scan. Lo and behold when playing around with Avast I found a registry clean option. USING THIS OPTION FIXED MY PC, I'm so happy! You guys should really punt these benefits when advertising your product.
Thank you very much once again!
