I don't know how to best describe this process but I'll try. I had some malware or something on my system recently that caused my browser to redirect to other internet sites. I 'fixed' this issue with some help from this forum, but now I'm having a problem where my computer keeps freezing whenever I leave it idle for a few minutes. All I've been running recently is Firefox, Itunes, and Microsoft word, so I'm not sure if the problem lies in any of these programs. After I reboot my computer, it seems to work fine, but after an hour or so, usually after left unattended for a few minutes, the screen freezes, and while the mouse is responsive, i can't get any of my windows to open. I've noticed that several times my word documents were in the process of autosaving. Also, the last freeze was different, as I kept getting notices that individual programs had stopped working and were shutting down. First was some sort of Cyber program which I had never heard of or used, next why my internet card, then I basically had to manually shut down my system. I'm in the middle of taking exams for school and this issue could not come at a worse time as I cannot run the risk of my computer shutting down in the middle of an exam.
If anyone has any idea of what to do please let me know.
