just got this off winpatrols website

Will WinPatrol conflict with other security programs.
WinPatrol works much differently than traditional Anti-Spyware & Security programs. We don't hook directly into any system resources and all system monitoring is done as read only operations. Many of our users also use programs from Norton, Sygate, McAfee, AVG, Panda, TrendMicro and no conflicts have been reported. Our users have also had success with Adaware, SpyBot as well as the highly recommended Zone Alarm.
WinPatrol has an advantage in detecting and stopping potentially dangerous programs but we still encourage the use of the anti-virus program of your choice to help you find and remove any portions that remain. For list of other vendors see

SpySweeper users have reported that Scotty regularly lets them know about changes to the HOSTs file. Apparently SpySweeper in its monitoring of the HOST file rewrites the file. We recommend you disable HOST file monitoring in either SpySweeper or in WinPatrol set the patrol time for HOST file to zero.
