restoring from Trojan attack

Hi, I am an international student in college, so I use two languages for my language bar. This is the first time I encounter such situation.
My camputer anti-virus software detected a Trojan attack so I deleted the Trojan file. But the Trojan program changed my computer setting completely. I did recover all my important files back; but there are still two problem I cannot solve, neither could my college IT department.
The Trojan program somehow changed my start menu so now all the files in the start menu has no sub-file, which should not be that way. The other problem is that I cannot see my language bar now, nor change my language, although I have two languages set up already.
Is anyone able to help me? It is be great. Thank you.

This is not my area, but you can remove the trojan but tou cannot remove the damage and changes it has caused. The files and folders you backed up need to be scanned with an good anti virus program before reinstallation. Once the computer is infected the only safe procedure is to completely reinstall. Trojans and viruses can embed themselves in the registry and settings, which it sounds like has happened. I would use diskpart and run the 'clean all' command. That is the only way you can be sure to get rid of it. Then do a clean install of the OS. Here is a tutorial of how to do it. Optimize for Windows Reinstallation . After following this procedure you could restore an image made before the infection. But you would have to know exactly when you downloaded the Trojan. A clean install is the best way.

A clean install is the best course of action, when the system files have been altered or damaged beyond repair.

Thanks Reaper. I just know that clean all is the only way to get rid of a Trojan. Thanks.

Is there any way I can restore it without reinstall the whole system? I asked because I do not want to reinstall my system.

The best answer is no. That is the omly way to rid yourself of the virus. From then on, do frrquent image of your OS.

It is safest to do a clean install(I know it's a pain in the a**), if you want to get rid of the malware & get your system up and running as it should be. After the clean install, you really should do at least weekly system images(to avoid situations like this), here's how: imaging with free macrium.

Sorry, but it is the only safe way to rid yourself of the trojan. None of us look forward to a new install, but sometimes it's necessary.
