I agree with you guys......I've run all the checks (MBAM, AdwCleaner, Avast9 etc.) and this PC is clean.....but I'll run/post.
I run Avast 8...now Avast 9 with no Virus found, MBAM Pro and CryptoPrevent on all PCs.
I found V9 FREE latest program offline installer (thx for your link too) and did a clean uninstall of V10 and install of V9....runs great !
Right now I have Comcast at 25Mbps pipe and works fine but if everyone on the house is online (kids with YouTube, Netflix going, etc.) some PCs can delay or not get internet. I see from other threads on NG on how it takes a lot of CPU initially for 15 minutes until it finishes its VM snapshots......however, I used V10 FREE installer...only shields checked in Custom....no NG, right ? I can say when I rebooted for first time the PC came up after logon and seemed OK....even could get to router fine and webpages fine......then is started to slow down to a crawl. The PC is a HP DM4 2.5Ghz W7 64bit with 4GB RAM.....a very quick PC in all other efforts. My only "guess" is this PC with V10 was doing something across the network out the router than consumed so much bandwidth it had same effect of heavy traffic effect of multiple users streaming/etc. on the other PCs attempts to get on Internet....don't think V10 effected other PCs "directly".
Anyway, I appreciate your thoughts but while I have nothing definitive to point to there are a lot of posts on CPU and memory usage (kind of like when V9/2014 was released) as well as SecureDNS, WebShield issues. I do not think SecureDNS is in FREE ? Anyway, I have one PC left to move from V8 to V9......will do that today. Think I may wait until a turn or two of V10 and see how the tweaks go with it and try out as it settles. I know many of you BETA testers are fine with current revision but as we saw with V9 release it took several turns of the code to get solid for "everyone".
