both also not the best, the best is n360 v6.0.
no antivirus or antimalware tool is 100% effective 100% of the time. If there was such a thing we'd all be using it and all other companies would be out of business. The "best" product is the one a person actually uses and keeps updated. Using
something is always better than using nothing at all, even if the product of choice catches only 90% if the bad stuff.
That's why on-demand scanners like malwarebytes, superantispyware, hitman pro, eset online scanner, trend micro housecall, comodo cleaning essentials, etc should be included in everyone's arsenal in the fight against malware.
Better yet, keep an updated system image available to restore your machine to a clean condition. Once a machine becomes infected, even if 6 different scans say it's clean, i believe you can never be 100% certain that the machine really is malware free. Some of the bad stuff can be so deeply imbedded it could be weeks before it activates.
Imho ... Fwiw
