Interesting one this. Ran Shields up 3 or 4 weeks back, from GRC.com to check the ports. Not long after when trying to shut down XP the machine got into a restart cycle and would'nt shut down. Had to switch it off in the end. Eventually I got it to reboot OK. No Reinstalls or anything. But checking the security I found that PG had ben totally disabled, all the extra protection items disabled, .exe prompt disabled, and all I had left in the list of protected programs were 18 Installer (.exe) icons, no details of the programs or anything. Ran virusscanner (Mc Afee version 8.0) and A squared freebie trojanscanner but no problems showing on the machine. All a bit weird. Not to worry, probably an XP thing. I uninstalled PG in safe mode and reinstalled it and it's been going ok since then. But I'd be interested in knowing if anybody else has had a similar problem. Keep on Processing. Mekon.
