i've been reading articles, reviews and posts all over te net for days. but after all that excessive research, i couldn't figure it out. now, i have standalone antivirus (with antispyware protection, and realtime protection for av is on) + an internet security suite with firewall in use and antispyware in use (and av not in use which i've disabled, for i'm using the standalone av) + (for extra layer of protection) another antimalware with realtime protection + winpatrol. what other security software out of the ones below can i choose to strenghten my protection that will work in harmony with the ones above and at the same time without slowing down my system, no system peformance impact, or at least minimal impact? and why, please? i can't see the difference between them CLEARLY. and, please, i don't wanna have any redundant, unnecessary ones to slowdown my system. here they are: defensewall hips, sandboxie, geswall, prevx, zonealarm forcefield, safespace, malware defender, bufferzone, virtual box. (don't take into account, if any is discontinued, or not updated recently). and, again, please, i want to keep my simultaneously in use security apps as minimal as possible. but also want to get the highest protection possible. i guess, you know what i mean. a very huge thanks in advance. salutes.
