My computer was lagging and was quite slow when browsing. I switched it off for the night and when restarting in the morning it took 5 mins longer than normal to load. When logging on to my normal user there was absolutely nothing in my User folders, no films, no photos, I can't access the net, the background had changed, no audio device installed. After looking in my C drive I found my original User (Silvia and Richard) with all the info I was missing, the computer/virus created "Silvia and Richard.Silvia and Richard". The trouble is when switching my computer on I can't access my original User as normal. Any ideas what the trouble would be and how I could fix it without a reformat? Just running a malware scan now.
