Let me just say right off, I hate Vista. Unfortunately, that is what came on the cheap little laptop we bought for the youngest to use. So I learned by necessity and so far so good. This one has me stumped though. Darling daughter managed to get the machine SEVERELY infected. I haven't had a chance yet to see exactly where it all came from but she had some bad stuff on it. I managed to clean it up (again, this is twice in a month that she managed to download the newest stuff out there). The problem is that one of those infections turned off her security center and now it won't turn back on. The microsoft website is useless. If I go directly into the firewall section, I'm told that the firewall is working, but I can't get the options to set up the antivirus or adware programs. I jsut get a message that "Security Center can't be turned on". Any ideas?
