FP (or F/P) means False Positive... a SAFE file, which Avast is erronesly detecting as being a virus.
If you have EXACTLY the same file/version being detected on your system, I'd say you're safe [as I believe I am]. If you're saying you have something "similar"... or perhaps ANOTHER file being detected as Sirefef... I can't make any such assertion.
Officially, we have to wait for avast to concur... to see if they adjust their database to no longer detect this file in the future. When/if they do, i'll report back here.
