Recently, my computer has become alot slower than normal. We had a freind tell us it was the memory and we needed another hard drive. He installed an E: drive onto our computer and transferred alot to it. Shortly after, my husband logged onto his desktop and the picture that he set as his background was gone. Also, some of his files had moved to different locations. A few days later, my desktop did the same thing. The other thing that happens is we start getting pop ups that say "Welcome to Windows XP" And then I will log on to Internet Explorer and it also welcomes us. It was like several things were reset on our computer making it seem like it is a brand new computer. It also runs very slow. I have Windows Live Care One that I am using for an antivirus. The otehr day my computer had froze up and started saying there were viruses. So I had Windows Live Care clean them out. Supposedly everything was OK. Can someone please help me and let me know what the problem may be? Is it a virus or maybe we have overloaded the C: drive? HELP! Thanks.
