The only problem that I had when I first got the update for Version 7 back in late February was the start up splash screen didn't go away. And this is on an XP system that is like 7 years old and runs very well. It could also be that I reformatted and reinstalled Windows last year, so there's not a whole lot on it.
After I used the Avast Uninstall Utility and reinstalled version 7, no problems at all, and this was the original version 7! I got the blue update pop-up notice last week about a new program version, and just updated through the GUI and it's fine.
People with problems may have other security software on their machine conflicting, or you might have to go to your previous Anti-Virus companies website. Not only remove the previous AV from Control Panel, but also get the program uninstaller for your previous AV program. But that can be hard if you have bought a used computer and you have no idea of knowing what was on it before. And it is a PITA to have to spend 6 hours reinstalling Windows when something messes up and your computer is not recoverable!
As much as I love Avast, I could see disgruntled users going to something like Microsoft Security Essentials (MSE.) The updates are only once a day and the protection isn't as deep-rooted as Avast, but it just runs in the background, no license keys to concern with, and it might be easier for newbies to install and remove.
In fact, I recommend Avast for Intermediate to Experienced users who know about security and computer protection. But for people who aren't into security at all, I tell them to go with MSE. But those are the only two programs that I like. I think all the other competitors are too bloated, and their detection rate is too weak,
Avast still has the most features and most frequent updates for the FREE PRICE! And this forum is simply amazing! 1000 gold stars for Avast dumping Iyogi!!!! Thank you!!!! I would like to see Avast dealing with their support ticket services better, but the greatness of this forum balances out that negativity.
