If you've become infected during the day, a nightly scan
is often not going to help you. That's because once your system
is compromised, the malware owns it and can do all sorts of
nasty things, INCLUDING disabling cron or infecting the very AV
binaries you depend on to secure you. I'm astonished you don't

For the inexperienced user it's better than nothing, but such users
are way better off getting educated as they rarely understand
even how their antivirus works, while trusting it to protect them
100%. And that often leads to their downfall.

Again, once you've become owned by a rootkit all bets are off.
Running rkhunter after the fact may or may not work. The more
sophisticated rootkits easily foil such attempts. They easily
fool you into thinking you've got a 100% clean machine. That's
kinda the essence of what they do.
Try to grasp it: Once your system is owned, it's not yours anymore.
Only thing that will save you for sure after that is a clean reinstall.

Of course it can happen, but you are very wrong to think that
simply having antivirus will save you. The best way to stay
secure is to keep informed about security and acting accordingly.
It's never as easy as simply having the latest anti-this or anti-that.
