Yes. Uninstall Intego Virus Barrier. You don't need it.
You will find this User Tip on Viruses, Trojan Detection and Removal, as well as general Internet Security and Privacy, useful:
Are you running OS X version 10.6.7, as the tag in your post says? If so, why not update to the current 10.6.8 version? 10.6.8 & the latest security patches from Apple protect you from the latest malware targeting OS X users.
Whether or not you also need A-V software like Virus Barrier X6 is a controversial subject. Some users are content to rely on Apple's updates & careful browsing alone but the relatively long interval between the appearance of the most recent Flashback variants & the availability of Apple's patch suggest that may be a bit risky.
