Why do some anti-virus software report an infection inconsistently?

There are circumstances when signature of a virus exists in RAM without being active.

If a scanner reports a virus active in memory only occasionally, it could be due to OS buffering disk reads. This keeps disk contents that include a virus in memory (for e.g. reading boot sector of an infected diskette) After running some scanner, there may be scan strings left in memory and it also leads to a false alarm.
