Help. We've got the Backdoor.Trojan on a file called WINDOWS\SYSTEM\logon.exe it was detected by Norton Antivirus, but we can't find a way to remove it as the program is running all the time the computer is on. Can anyone tell us i) is it an essential program; ii) how to close it and repair/delete/quarantine the trojan? Please bear in mind we are complete novices when it comes to computers. Also can I add a thanks to the posts re: msinfo.exe We followed the advice on that thread and sorted out THAT problem.

When you start your computer tap the F8 key while the computer is booting up. This will take you into the safe mode. When you get into the safe mode, run your virus scan and delete the files that Norton finds.

Capt. After one failed attempt (we pressed F8 at the wrong time) we finally got rid of the file. I assume rebooting following the deletion takes us out of safe mode, if not please let us know. Do we do need to find an uninfected copy of the file to re-install (the computer seems to be working normally now)? We are very grateful for your help. Many thanks. Maybe we can get some sleep now!!

Thanks for letting me know how things went. By now you will know that shutting down the computer will take you back to the regular startup. The file only contained the Trojan Packet, which is why Norton could not clean it, as there was nothing to clean. No file needs to be replaced. Just make sure that you do not open attachments that come with your email, even from frieds without scanning them before openening, "you have no friends on the internet". Friends do stupid things and virus/trojan/worm packets are automatically sent out to anyone listed in their address book, which is why you must be careful when you get things from a "friend". In Outlook Express set your email setting in View>Layout, so the preview pane is disabled. Set the security setting to not allow attachments that might have a virus, etc. Get a firewall, Sygate, if you do not have one. Take care and all the best!

Capt Can we impose on your knowledge again, please? We are having trouble with Internet Explorer. After using for a while it locks up. The message is that it cannot connect to the site requested as it may be busy, being repaired... We've tried the refresh as it suggests, but that doesn't seem to work. At first we thought it was the site we were trying to reach, but changing the address to another brings similar results. AOL items (mail, news, etc) still work when IE jams. Any suggestions? I did read a thread called Internet Explorer Broken, but wasn't clear on the solutions there, or if they applied in our situation. Any advice gratefully received. Troubled Novice
