No, I haven't tried Ad Muncher, but took a look at it. I already have 3 active security products, plus a trial version of the paid version of MBAM. ESET NOD32, SAS Pro w/lifetime updates & Windows Defender, plus using common since computing habits, is my security posture using Windows. SAS does finds trojans that some AV's misses. When I had MSE (the original version), it found a few of them.
When I want to take a chance & throw all cautions to the side, then I use Linux Mint, sometimes in virtual mode for quick access, but I have it installed on a HDD alone, too. Unless one is logged in as root (same as administrator in Windows), the OS won't get broken by a virus or other malware. While it's possible that the user may spread bad code, it won't affect the user's computer at all. I run Klam AV on it, as a manual scanner.
When NOD32 subscription expires, I'll go with ESET Smart Security, that will give me the firewall too.
I don't need a new keyboard at this time, the one that I have made by Logitech is still fairly new. But that's neat, one that'll encrypt what you type. There's encryption software on the market too, that protects what you do on the net. It's especially good for those with wireless routers.
