After using NOD32 for a number of years with no problems, several processes have stopped automatically loading when I boot up my computer. They are:- NOD32 Control Center, Winpatrol, MS Antispyware, and the automatic logon to my Telstra Bigpond broadband connection. The worry is that, all these, with the exception of the broadband logon, are security programs. I wonder what could have caused them all to go missing at the same time. They do not show in the system tray until I restart them manually. A scan shows no apparent virus. The PC seems to run without any problems. i) Is there some known malware that specifically stops security programs from auto loading at startup? ii) Can I get them to auto load again without uninstalling and reloading Currently, I start them manually each time I boot up. But this is not satisfactory as I could forget. Any help would be greatly appreciated.
