I have a problem, at first i noticed that the option to view hidden files cannot be enabled, I used Kaspersky but according to which no Virus was detected. Recently my PC went haywire it started acting on its own and once i press alt+control+delete it displayed the calculator. after viewing several forums i thought the best options is to format my C drive and reinstall windows, however the problem never siezed. My mouse(USB wireless) is still acting wierd and nothing can be done, antivirus and antispyware still shows nothing. can anyone help? This PC i am talking about is not connected to the internet. will include hijack log in a while Attached are the logs and necessary files. Today i noticed that the problem occurred when i connected my wireless USB mouse and keyboard. please let me know a solution urgently.
