I also am having problems since the latest update. When I click shutdown, it goes to a blank screen & then turns blue with -- An error has occurred, press enter to return to Win. etc. etc. Error:0D:00BF:BFF648EE -- & the only way to shut down is the off button. I have done the selective startup thing in msconfig & Avast seems to be the culprit. I now-- Stop On- Access Protection & Exit-- before clicking shutdown, with no lockup. OS Win ME Any ideas?
