As explained in
https://forum.avast.com/index.php?topic=168064.0 I have used Avast free for years, and had a recent (this week) bad experience with the latest software update.
But that's just the latest thing that's making me grow wary of Avast and considering switching to AVG.
One is the constant barrage of popup ads. I know, I know, I'm using a free product. But I've seen computers with AVG, and these don't have nearly the number of bogus "sale" ads, or "your computer has 583 pieces of junk on it" inducements to buy another product, that Avast inflicts on my computer.
Of more concern though is something that happened last week.
A "quick scan" on Monday found two instances of malware, in a temp file directory. The "infected" files had been there for more than a month, and had never been an issue. I had Avast quarantine them.
The next day (I restart my computer each night so it's fresh when I log in in the morning), the computer had a black DOS screen with white characters, saying that Avast's boot-time scan had found infected files and dealt with them.
I clicked through that, I went to a normal login screen, logged in, and instead of seeing my normal desktop, I saw an iconless screen with a message at the bottom right saying that my version of Windows may not be genuine. I powered the computer down to a full shutdown, started it, and logged in, and all was normal.
I then used system restore to roll the computer back a full week, and since that time, the computer has booted fine, run fine, and Avast has found no malware.
But this malware discovery bothers me because I practice VERY safe computing, and for all intents and purposes, have NEVER had malware on my computer (on which I'm the exclusive user).
Given the sketchy and dirty feeling I always get when encountering the omnipresent ads, the odd malware detection and boot issue from last week, and now the scheduling and scan issues with the newest (March 2015) version, I'm starting to feel "Avast fatigue."
Any comments on the issues I raise? Anyone else experiencing or feeling the same things?
