I have an Asus system with Windows 7 running on it. Whenever I try to save any file from internet, it does not save the file. For example, if I try to save an image using ‘Save as’ option, I get an error message saying “There are no more files.” If I try to replace similar other file it saves as usual. I went into processes in Task Manager and I found some processes like ATKOSD.exe, ATKOSD2.exe, Atouch64.exe, csrss.exe, nvvsvc.exe & WDC.exe running which previously I had never seen. I scanned my pc with Bullguard internet security, but no virus, malware or such suspicious object was detected. I cleaned the cookies from my PC but it too didn’t help, the problem still persists. The processes which I have mentioned above, can someone tell m which of them is harmful?
