Thanks for the link.
I have loved avast, so I did go through the whole process of repair as mentioned in those links, but the system was still so slow. Avast wasn't my first program removed or repaired to try and fix the slowness. A few other programs were removed first, as I had learned to trust Avast. System was checked. Drives were tested with more than just what Windows supplied basic tests. Speed tests and network connectivity was tested as well.
Been doin this work for a while. It wasn't until I uninstalled avast the system returned to it's normal, faster speed. BUT... That's when page opening issues occured and I tracked that down to the Browser Security Extension Avast had left behind. It would have been great if the Repair had worked. Would have saved me a heck of a lot of time. Back-up, removal's, tests, re-installs, etc....
One interesting thing was, when I went to use another AV, it found one Avast had missed. I mentioned it elsewhere. PennybeeLinkury. That was found with just Windows Defender. Hopefully they add it. It was deleted so, I couldn't submit it. Best I could do was mention it so they'll look into it...
As I said, I loved Avast, random annoying pop-ups and all, and I may be back to use it again, once I read the new issues are resolved. But for now, what I am using seems to be working well, with less pop-ups as well. Time will tell.
BTW, Congrats on the "59 Years of Happiness".
