The reason FF is under the gun with Secunia is because until 3.6.2 was released, there was the threat of "arbitrary code execution". That's one of the worst threats to your computer and security. Look it up at Wikipedia, it describes the threat in detail. FF claims that 3.6.2 "fixed" the problem, however 3.6.3 was released less than two weeks later. FF is apparently the most affected browser, in regard to this threat, at least in Secunia's opinion. They also consistently report that Adobe is a threat, but post "patches" for this problem. I don't have it installed on my desktop, but I do on my laptop, on the XP Pro partition. No doubt, you can't rely on a single organization for your "security" alerts. That's why I run layered protection, in hopes of avoiding these threats. But no matter what any program like Secunia "reports", or what level of AV or malware protection you have, no one can lay it all on the line and say you're 100% safe. That's why I don't have Secunia on all of my Windows installs (eight of them). That 100% rating is a false sense of security to many. I do have an XP install that I use it on for evaluation purposes, to see what it generates. The major threat that I mentioned above came from another forum that I'm a member of. At first, I defended FF wholeheartedly, saying that it wasn't possible with FF. I was almost thrown off of the forum for my remarks in this regard, being that FF is the major browser for Mint 8 (and most other Linux OS's). The moderator directed me to read the 22 or so pages of the thread prior to my remarks. It turned out that the problem was first reported in 2006, at that point, Secunia caught on to it, and they've been on FF's butt since. FF claims that 3.6.2 fixed the problem, but there's been at least two more attacks since then. So now you can see what Secunia has against FF. The other issues that Secunia flip flops around on, I haven't seen yet. I would list the place where the thread in it's entirety can be read, but although it's not a competing forum, I don't want a strike on me here for listing it.
