Since ditching NOD32 several weeks ago I've tried several AV programs - KIS7, F-Secure and Symantec (Corporate Edition). I liked KIS7 but it did make my browsing extremely slow. I did, however, 'feel' very safe with it. F-Secure seemed ok, but it didn't seem too customizable. Symantec, however, surprised me. It's interface is pretty hideous, but after reading lots of bad press about machine slowdowns, etc, I was surprised to see that I noticed no notable slowdowns at all. My question is - why, when Symantec seems to always figure at the very top end of the AV tests (with Kaspersky), does hardly anyone use it? Is it a slowdown issue? Is it because it is ugly to look at? Surely the detection rates speak for themselves? After having it installed for a couple of days it seems pretty impressive. I'm just curious as to why it's rarely mentioned here, apart from being associated with Norton (remember, I have Symantec Corporate, not NAV 2007 installed). Is it really a 'bad' AV? Should I dump it for Kaspersky (and the agonizingly slow browsing with Firefox that I don't have with Symantec). Your valued opinions are extremely welcome.
