But for those who do run security-products on top of their IS suites, it would be nice to know why.
I also run Hitman Pro and MBAM as on-demand scanners for when I want a second (and third?) opinion on something, and I'll sometimes send things to VirusTotal or Comodo's file verdict service. (Valkyrie) I've never had a problem, but it's never a good idea to be overconfident in your security suite. :blush:
Other than those, the only other security type application I'm running is Sandboxie. Not so much from the angle that I don't feel my security suite may drop the ball, but more because I just hate all the crap that browsers tend to accumulate during normal operation, (especially things like LSO's, Super Cookies, and Zombie Cookies) and having Sandboxie automatically delete all of the contents accumulated during a browsing session when I close the browser is the easiest way to basically start with a clean slate each time I open a browser.
I also like to use Sandboxie for test installations of new applications. Similar to the browser subject above, this is not so much for security reasons, but out of curiosity. It makes it very easy to see what changes an application will make to your system when it is installed. Just browse the sandbox contents and you can see each and every file that an application drops on your system. I don't however, use Sandboxie for long-term application testing though. I use a VM for that.
And, the fact isn't lost on me that Sandboxie adds another layer of protection on top of my security suite.
I also have a VM clone of my physical machine that ordinarily has a completely different security setup. (Which tends to change from time to time) Again, more for curiosities sake than anything.
