"Wow! I don't even notice that the thing is running."
Fast Full scan. None intrusive to my online browsing when updation or scanning. The active scan is the BOMB! Between Mac Site Adviser and Avast, I can brouse worry free. Avast has blocked may exploites from my computer while I am browsing websites. I have been using cnet for years and I have to say this is one of the top 3 programs I have ever downloaded. I am very impressed with advast, as well as the cnet staff for its accurate reviews.
If you use the webrep addon (sandbox) it can cause problems in your browser. It can slow, crash, or close your browser. But, luckly the active scan is so good with Mac Site Advisor I haven't need the sandbox.
I have had many antivirus programs and of course all of the mainstream. None of them and I do mean none of them have performed even close to Avast. Once again I am writing in a review that the best softwear of its type is a free version. One can only imagine what you get from the Plus version!
