If I leave my PC unattended for a while, sometimes I get the error message, synchost has caused an error. Can anyone tell me what this is please? I did a search for synchost.exe and found it in C: Windows. I'm running XP Pro. Thanks.

This trojan allows a hacker to remotely take control of the infected computer. It copies itself as 'SYNCHOST.EXE' into the C:\%Windir% directory and hooks the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

With the value: "Remote Access Slave" C:\%windir%\Synchost.exe

By modifying the registry in this way it allows itself to execute after every time the computer is re-started.

The trojan also opens port 4999 to allow the hacker access to the infected computer.

Seems you need to do a trojan / antivirus scan pretty soon.

Hi Diodorus.

I have NAV and I did a scan and it found nothing. What do you suggest I do to remove this?

I've tried to do what Norton has suggested, but the trojan appears to still be there. Is there something that I can simply download that will remove it?

Hello VoG.

I downloaded and ran Trojan Remover. It did the scan and it found nothing. I did a search and synchost.exe is still on my PC. I'm a bit baffled. Is it a trojan or not?

have you deleted

Remote Access Slave C:\%windir%\Synchost.exe

from the registry key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
