Well good news bad news. No matter what Version I tried to install, I had the same issues.
But, I finally managed to get Version 8 on this PC, after several tries That was the ONLY Version that didn't freeze my PC. But (yea again, but) my keyboard still would not work. However after rebooting several times (4 or 5?), my keyboard began to work. And, remember, my keyboard is only NOT working inside a Browser; any browser. It works fine within W7's environment.
I know this sounding more like a Keyboard/driver problem, but when I use this Keyboard and mouse on my second PC, which is set up exactly like the one I am having issues with, the keyboard works fine. On that PC I am still using V8. But as soon as I Upgrade to 9 the same thing happens. And again, as soon as I uninstall avast! 9, everything works OK. In fact, I've tried other AV programs and I do not have any issues. All this leads me to believe that somewhere in avast! 9 (2014), there is some kind of bug.
I've run SFC scans, online AV + Standalone scans (with other products), boot scans, Malware, cleaned out old install files, tried installing on a clean boot, but I can not get V9 on either PC without running into an issue. PC freezing, not updating the defs', keyboard not working, etc. So, for now I guess I'll have to run older Versions on both of them.
I mean other that a Repair install to actually see if it's a W7 issue I can't think of anything else to try. Plus, with both PC's having the same problems, with the same Versions, with same software, when the PC's are the exact same, something tells me that would do no good.
So, if anyone has a thought on this I would appreciate it.
To everyone who has tried to help me, Thanks much.
