Running Win XP on Athlone 1.333 with 512 RAM. Regular user of Hijack & Power Tools. Place my trust in CounterSpy, Sunbelt Firewall, AVG, Adaware – you name it I'm running it. Recently noticed when doing the weekly housekeeping a total of two dozen registry entries containg 'HRZR-EHACNGU-…..'. Power Tools 'removes' them, but on reboot they have reappeared. Hijack and CounterSpy reports are clear. Google search throws out various geek sites full of gobbedegook (to me anyway). What's going on here?
