kanoahryan, this sounds like a software issue. In particular it sounds like Ransomware. Read this [http://www.microsoft.com/security/portal/mmpc/shared/ransomware.aspx|about ransomware.] There are a few pieces of software that you could try, one of them is described [http://esupport.trendmicro.com/solution/en-us/1096206.aspx|on here.] Give this a try and let us know what you got. Hope this helps, good luck.
