for any others trying to uninstall ZAlarm,it leaves behind'True Vector Service',in bits in Windows sys.32 files,true vector is the part that monitors internet, so now I realise why it was interferring with Windows FWall !!! This bit can also muck up re-install of Zalarm,Basically a right PAIN !! Thanks for tip on Sygate, have to be quick tho' bought out by semantec and is withdrawn from many download sites (found out today)
