That would NOT prevent all false positives. A virus checker will EITHER sometimes give a false positive OR sometimes fail to identify a virus (false negative). Since a false positive has less serious consequences than a missed virus, that's the side any practical virus checker should err on.
A virus checker that ALWAYS worked (correctly) is impossible. Impossible in the mathematical sense, not just "nobody has written one yet". You can prove this the same way Turing proved the "Fundamental Theorem of Computing" (that a checker that could correctly decide if a program would enter an endless loop). Just substitute "act like a virus" for "enter an endless loop" in Turing's proof.
