What is better?

What is better between an antivirus that removes files wrongly classified as suspicious or the lack of the  antivirus at all?

The antivirus from Comodo Internet Security 3.10.102194.530 is seeing Heur and unclassified mallware everywhere, even when heuristic scanning level is at the lowest. When the incidence of false alarms is so high, the user may be at a real risk of running a virus on his/her computer. At this point turning off the heuristics is the only solution for this suite. I hope they will fix this major flaw, or I will be forced to switch to other products.
