On the pc everytime a file is downloaded it is not able to run. Examples windows updates will not install adobe update gives an integrity error. This computer was just put on the Internet for the first time this week I'm thinking its an ISP error but if it's an issue within the computer what could be causing it. A disk check was ran and came up with no errors all cookies and temp files were deleted. None of these fixed the problem and the ISP is going to be called but I just wanted to know if anyone else had any ideas.
