I have the same problem I thought lowering the Zone Alarm would lead to more problems so rightly or wrongly I removed the already installed offending up-dates and re moved auto update from my windows programme and things are running fine at the moment ah! just had a reminder that I have updates so I have elected to deal with them later ,Why can't Microsoft get involved with a obvious problem or do they want you to use window firewall ?
Sorry to use your post TEAK but I would welcome advise on this also hth Tez
