Security

I would prefer if we treated Social Security like an insurance plan. It's there in case you need it but you don't get it if you don't really need it. I have fire insurance on my stuff but I don't plan to burn it down so I can get that money back. source

I don't think the commercial versions are significantly better, but in general they seem to do more of the configuration for you that you have to do yourself with free software. Sometimes this is good in that you have more control but in some cases it does make for an uphill struggle. source

I think security software is only as good as your surfing habits. Even if you have the whole shebang of internet security doodads pero you frequent shady crack and pron sites and download stuff from the net without regard then you expose yourself to security threats and no matter how good your security software is you are bound to get infected. source

I prefer YesScript , it's a NoScript spinoff that allows JS globally but lets you blacklist invidual sites. I use it more as a performance enhancer coz I've noticed some JavaScript-heavy sites really bog FF down. source

Kaspersky is way better in detection and protection. Bitdefender uses two engine to detect virus and yet it still score very low. source
