HELP !!! Winlogo.exe Trojan !!

You can either click the START A DISCUSSION button (which you did) or ASK A QUESTION button beside it. You will be ignored here, answered there.

First thing's first, reboot in safe mode and shut off Automatically Restart on System Failure.

If XP,
1.
Right-click My Computer, and then click Properties.

2.
Click the Advanced tab.

3.
Under Startup and Recovery, click Settings to open the Startup and Recovery dialog box.

4.
Clear the Automatically restart check box, and click OK the necessary number of times.

5.
Restart your computer for the settings to take effect.

Now instead of restarting it'll just crash or go to a Blue Screen where you'll need to reboot.

You'll also need to post your operating system, not everyone uses XP.

Oh what the hell, I'm here now, I'll take the flogging from peers for helping in this forum.

To start, boot in safe mode with networking and go to the following address and conduct an online scan:

Oh and turn off system restore before you do anything, otherwise removed fils may be replaced on reboot.
