"Takes actions without asking or even telling you"
Industrial strength protection
Low system impact
SONAR technology silently deletes files
The last version of Norton introduced a set of heuristic protection tools, among them one called SONAR. It is basically a reputation engine. If some particular file is, in Symantec's judgment, used by an insufficient number of people, then it is treated as a virus and removed from your system. That in itself is annoying, but what turns irritation into a MAJOR BUG is that Norton does not tell you what it did. No warning, no asking for permission, no informational popup telling you what is going on and why, not even a history log. It is up to you to figure out why that program you thought you had vanished without a trace. Making major alterations to my system, silently and without my permission, is the one behavior I simply will not tolerate. Yeah, you can turn off the "feature." And the next time Norton updates, it will turn itself back on. I've been testing Avast on another machine and so far I'm pretty happy with it. I don't see the point in paying for antivirus any more, and certainly not in paying for deliberate irritation.
