Nod is flagging my new install of Spysweeper Version 4.0.1 (Build 323) Using Spyware Definitions 486. I get the following message from Nod when I startup my computer. C:\Program Files\Webroot\Spy Sweeper\WRSSSDK.exe probably unknown NewHeur_PE virus. I did not have this problem until I upgraded to the new version of Spysweeper. I downloaded the file from their server. Could this be a false postive report ?
