I'm curious if anyone here has tested these though?
Such as SkyShield.
I already know about the others like IObit malwarefighter which considering it's constant ZERO level of performance should be considered fake by now imo.
I think another missing from the list would be Anvisoft Smart Defender. (also like malwarefighter, basically useless, even the paid version doesn't really amount to anything).

Voodoo shield technically isn't an antivirus but it can check files on virus total and is pretty useful to have around.
(It's basically a sandbox for your browser).

There's also
http://www.csantivirus.com/
Which apparently now uses sophos engine. (So they say. but I haven't seen anyone test it yet).
There's also ClamWin + ClamSentinel (two seperate programs, you have to install ClamWin for ClamSentinel to work but once you do you have a real-time antivirus purely based on ClamAV all of it is opensource).

And

I don't recommend softpedia. Most of their downloads are outdated.
ClamWin and ClamSentinels developers host their downloads on sourceforge which is 100% safe and does not include any bundled crapware.
