Virus: Worm/Autoit.AAWI found in temp. internet files....

My Anti-Virus Software detected the virus shown below. I wasn't able to "heal" it, but I was able to quarantine it in the virus vault & delete it. Now that it's deleted, is it really GONE?? Also, can you tell me about this virus, possibly how I got it & what it can/will do, etc.?

Virus: Worm/Autoit.AAWI found in temp. internet files/content/IE5/89QV85QZ/Setup(1).exe

Thank you for your assistance,

Hello.
Hard to tell what it is. Many AV don't like anything designed in AutoIT development language.
