I think i open a zipped file and after that the computer shutdown automatically.
When i restarted the computer, my antivirus, my firewall were disabled. When i tried to run them manually from the Start Menu, it displayed the following message:
D:\Program Files\ESET\ESET NOD32 Antivirus\egui.exe is not a valid Win32 application.
D:\Program Files\Agnitum\Outpost Firewall Pro\op_mon.exe is not a valid Win32 application.
I tried to run Spybot - Search & Destroy, but the program did not open.
I tried running Trendmicro HouseCall Online, but when it was scanning, it displayed message that certain files are not able to upload.
Then i tried to run HijackThis, it displayed the same message:
D:\Program Files\Trend Micro\HijackThis\HijackThis.exe is not a valid Win32 application.
I tried System Restore, it did not work.
I tried to go in Safe Mode, it did not work
I really dont know what to do, I am sure that my computer is infected.
im running Windows XP SP3.
