Oh! You mean computer security..... AVG right now. It's a PIA, but it's free. Looking for something else. Free or payware doesn't matter as long as it is UNobtrusive and works.

M1 Garand.
M1 Carbine,
1936 .38 Cal Police Special
M1911A1 .45 Cal Semi Automatic
Really annoying and slightly threatening hamster named "Frankie".
You get through these....you can have it.
Frankie pees everywhere....

You may have noticed my collection of firearms is of the historical nature. Not the best for self defense...
I would love to have an MG3, but it's an automatic and I do not carry the requisite licenses. I spent a good bit of time carrying the M60, which, like the MG3 derive from the WW II era MG42. The M60 is significantly heavier (we call it the "pig"). They both fire the NATO standard 7.62 cartridge.
