Backdoor Trojan

When I restarted my computer today I got a error saying my computer couldn't locate a system librarydll and that my computer watch was disabled I don't know when to do and I need help thanks.

 

Please state the exact error message without paraphrasing for the forum to more effectively help you.

Update your antivirus, temporarily disable your screen saver (choose None) and scan with your anti-virus set to scan All Files. Update and scan bi-monthly.

You can scan on-line to double-check your Windows scanner at http://housecall.trendmicro.com/

*** Mandatory (get a firewall of any brand) - Get free Zone Alarm personal firewall anti-hacker countermeasure from http://www.zonelabs.com. (not the ZA Pro demo) 'Don't let anything out to the Internet you don't know what it is.' Also please see http://www.firewallguide.com/ for more information on why all on-line home computers should be firewall enabled.

Get the firewall if you have none, then do on-line scan.

 

The exact error comes up when I log onto my windows XP. The error says exactly this: Library watchdll.dll not found
System watching is disabled

I ran my norton anti virus and it didn't catch anything.Thank you for your help.

 

It either belongs to a keylogger or this trojan:

Please do this:

Go to http://www.spywareinfo.com/downloads.php#det , and download 'Hijack This!'.
Unzip, doubleclick HijackThis.exe, and hit "Scan".

When the scan is finished, the "Scan" button will change into a "Save Log" button.
Press that, save the log somewhere, and please show us its contents.

 

How do I get the log to appear on the reply?

 

the logfile will open in notepad........click the edit tab(top left)scroll down to "select all"....the text will all be highlighted,right click and choose "copy" and then rightclick on the T.S.G text pane and choose "paste".........then submit your reply.

 

Thanks for your advice but I found an alternative way.I opened my programs and went to accessories, from there i went to system tools and clicked system restore. I set the day to friday(day before download) and it is all fine. Thanks for your help anyways
