SearchForIt is a false positive. You are finding it when you do a scan with Spybot. What Spybot is picking up is the registry entry of the blocked item in SpywareBlaster. You don't need to do anything, just wait for a future update from Spybot when the matter will almost certainly be resolved.
After running a scan with Spybot don't delete SearchForIt as you will lose the protection against it given by SpywareBlaster.
