My wifes friend let an exchange student use her computer running XP Home SP1 over a period of a month and she picked up all sorts of nasty spyware, adware, viruses,trojans and who knows what else. I have been able to clean most things out but when I used AVG antivirus to clean out some trojan horse Startpage.21.AS files such as xmllib.dll, iexplore_dbg.exe and explorer32dbg.exe the desktop icons, start button, systray and taskbar are gone in normal mode. They do show up in Safe-Mode which is the mode I was in when I ran the HijackThis log. I must not completly understand AVG because I can't restore the files (hilite the file, right-click, restore). When in normal mode I can ctrl-alt-del and run programs from the task manager. I have followed other posts such as 'How to remove Begin2Search/ etc' and I have fixed some files using Hijackthis but not all files stay away. SMSSU.exe and tmntsrv32.exe keep coming back. I have tried reloading XP (not the Recovery Console) without success. I have been working on this for a week and I know I'm missing some things I've tried and I am open to any suggestions. I really don't want to scrub this thing, there are a lot of pictures and downloaded files that I'm not sure are safe to backup. I don't want to infect again and I'm reluctant to hook up to my home network since I don't trust these vermin. I am attaching the hijackthis log taken in safe-mode.
