task killers are outdated and pointless on the current versions of Android. The OS manages memory better itself now, and using task killers now actually uses more battery life trying to close out apps than letting the OS manage things.
Anti virus programs are pointless as well, seeing as how there are no viruses on android. The reports of stuff in China was actually shady apps taking advantage of stupid people not reading the permissions they grant to those apps. Apps can't do anything on android unless you grant the permissions, so just read those before installing anything.
