I let a friend use my computer, and he promptly installed a trojan called humortadela.scr. I caught this and deleted the scr file as well as an exe file that had been downloaded. I ran a virus scan (Mcafee 9.0, which is always up to date), and a stinger.exe scan. I have Zone Alarm installed - no untoward programs have been configured for internet access. I ran SpyBot. Theoretically, there is nothing wrong. However, every time I log on, I get a program trying to access the internet. Since I'm not connected, I get a little window with a big red "X", ''Socket error # 10065 No route to host''. I've looked at every registry key and ini entry I can think of, used msconfig, tried to identify the process in the task manager, and cannot figure out HOW and WHERE this program is being called and run! Any ideas?
Around this same time, my computer has started not wanting to shut down. (I assume these problems are related, but maybe not - I haven't changed any hardware, and had never had problems before). I have XP SP2, all patches up to date, have scoured this forum and tried all tricks on all sites suggested. I downloaded the ''shutdown.exe'' file suggested, and even THAT doesn't work. The start menu ''turn off computer'' button brings me to the options, I choose Turn Off, the hard disk begins to show some activity, then it seems to just spin with tiny, intermittent access bursts. And that's it. The computer doesn't hang, I can continue using it, but that's as far as it goes into the shutdown process. I go into task manager and FORCE a shutdown by disabling the DCOM service, and then turning off the power when the system tries to reboot. Also by using the downloaded shutdown.exe utility with the -f -l -u switches, the system logs off, returns to XP and gives me a choice to turn off user - which works.
So, this shutdown problem seems to be connected to the system not logging off, rather than the type of problems discussed elsewhere in the forum.
