What I'm not sure about is how many I need to make sure I'm completely covered. One for viruses, one for malware, and one for rootkits. Are these three enough or do I need something more? If so what is it? Would having several of one type give me added security coverage (Like having Malwarebytes Anti-Malware and Emisoft Anti-Malware)? If so I do know that I should only have one performing real time protection to avoid conflicts. Is spyware covered in these or is it something additional I need to get?
Protection is my biggest concern. So what are the programs commercially available today that offer the best protection? Keep in mind I'm looking for the best of the best in terms defense and removal, so even if you know some really good free programs, I don't mind spending some money on ones that have a price tag if they're better and would prefer to do that anyway. Ones with anti-exploitation features would also be preferred. Also I know that there's no universal "one size fits all" solution that works for everyone and there is no single best one overall. I'm focused on the quality that the programs offer in protecting against threats to my pc.
While its not a priority, any of these programs that are also easy to use and aren't intrusive or obnoxious while I'm doing other things on my computer would make them more attractive to me. But not if it comes at the expense of protection.
