Because you seemed either you misunderstood doing System Restore from a Command Prompt or could not get the MS Article, I printed the article for you. It works. I have done it many times.
And do not forget to do virus scan as I suggested.

SUMMARY
Windows Millennium Edition (Me) includes the System Restore tool, but you cannot start the System Restore tool from a command prompt. Because of this, it may be useful to start the System Restore tool when you are unable to start your Windows Me-based computer normally or in Safe mode. This article describes how to start the System Restore tool when you cannot start your Windows Me-based computer normally or in Safe mode.
MORE INFORMATION
To start the System Restore tool when you cannot start your Windows Me-based computer normally or in Safe mode, you can temporarily change the Windows shell from Explorer.exe to Progman.exe:
1. Start your computer by using the Windows Me Startup disk.
2. At the Startup menu, choose Minimum Boot.
3. At the command prompt, type edit c:\windows\system.ini, and then press ENTER.
4. Edit the shell= line so that it looks like this:
shell=progman.exe
5. Press ALT+F, and then press S to save the changes to the System.ini file.
6. Press ALT+F, and then press X.
7. Remove your Windows Me Startup disk, and then restart your computer. When your computer restarts, Program Manager should start. If Program Manager does not start, repeat steps 1 through 7, being careful to follow these steps exactly, and then continue to the next step.
8. On the File menu, click Run, type msconfig in the Command Line box, and then press ENTER.
9. Click Launch System Restore to begin restoring your computer to a previous, functional state.
