I have a mid 2009 macbook pro (2.53 ghz core 2 duo, 4 gigs ram) lately though the fans have always been running and activity monitor shows the user's CPU usage is over 50% even though i don't have any applications open. I'm thinking of resetting the SMC but don't know if that's even the problem.
Got a tip for us?

Try resetting the SMC, especially if the fans are running high without increased heat. Check Activity Monitor and change "My Processes" to "All Processes".
yea i found the iantivirus to be using like ~98% of CPU so i forced quit and everything's fine. Wondering if anyone else had this problem? I have version 1.36
You don't need any antivirus apps to protect your Mac from malware. I recommend you uninstall it.
Antivirus appears to be a rather common cause of unexpected load under OS X. I have rarely had any problems with it on other platforms though.
