Been using Avast! for a very very long time. Pretty flawless, I think, I don’t know, it just does its thing silently in the background (yes, you can turn off the voice that says: “Virus definition have been updated!”). I used it on Windows XP, Vista, 7 and Mac OS X since Mountain Lion. Had maybe one small issue with XP, but none with Mac OS X so far (almost 3 yeas now and the computer is running at the same speed as it did on day 1.). Do I have viruses? I don’t know. I’m just happy with the way things run.
There’s just one thing about Avast! i cannot figure out. I think about it all the time. I can’t even sleep at night anymore because of it. Why does the program’s name have an exclamation point???
OK, if I may… please use a slightly more legible verification widget. I have to reload at least 10 times because I can’t tell what the letters are;
