I'm having the same problem.
My laptop started an auto update which appeared to freeze. I shut down my laptop after waiting for over 2 hours for the update to complete. When I rebooted, I had a number of ugly things going on. No internet, but could see other PC's on my home network. Laptop auto rebooting every 10-15 minutes. Windows reporting Malware issues, McAfee reporting problems, but unable to fix. Unable to shut down the laptop, had to shut down with the power button.
After spending several hours attempting various approaches, I finally did a restore from before the McAfee update and everything started working. Unfortunately, I didn't shut down the auto updates, and after about 10 minutes, it attempted another update, which put my laptop right back into the same state.
I restored again, shut down auto updates in McAfee, and the laptop is working fine.
At this point, I don't know what to do about updates. I am leary to perform any updates, manual or auto, for fear of trashing my laptop again.
Whatever is causing this problem does not seem to have any impact to my PC's running XP, only Vista.
Can anyone provide any information regarding this problem??
HEY,I have been haveing some problems myself.Although mine is of a differant nature,i am still waiting for answers.For some reason i think the conclusion made is that most of the problems of late only effect XP which i don`t think is the case.But i am not a computer programer.Anyhow,the only thing i can suggest is to go to the top of this page and clich tech support and load the virtual technician.This will hopefully tell you is everything is in working order and if missing any componants fix them with any luck.When its done it will have a log you can post with an id number.I am sure someone else can help with that.Or you can do an online chat and see if they can fix it.also under useful links at top of this page.Last but not least you can do the old uninstall reinstall.I think you should leave the updates off for now if that is helping,until somebody from Mcafee can answer the dat question.
Good luck Jack
