Hi Guys I have this problem in my PC, I'm using WinXP SP3 -updated-. Yesterday and suddenly, when I start IDM or open Winrar or any compressed files (rar, zip ..) Windows shows this error message: windows cannot access the specified device, path , or file. You may not have the appropriate permissions to access this item If you google it, you'll find many people in many forums having this issue (may be you'll get it ), I tried some solutions but .. this message still appears.. I think that it's not related to any virus (I use KIS 2010), may be a security issue in the registry or in some windows configurations.. Any ideas guys, any solution? ... I don't like to format and reinstall.
