After a mishap with some random file clinging to my recycle bin, zz_tophat said I should use a combination of Advanced SystemCare Free, IObit Security 360, and Spybot Search & Destroy.
If something get's past one antivirus program, it'll likely get past all the others too, unless they're all rubbish.
Just keep your OS firewall
on and download whatever antivirus no one's complaining about, you only need one antivirus program, not 20.
Oh yeah and don't play ad games or download research movies.
