Each time I boot up my windows, I get this message :

"Error loading C:\Windows\system32\awts TLDS.dll
The specified module could not be found."

This message started coming after a trojen was detected by my Windows Defender and was successfully deleted.
Anyone who knows why this message is coming and how to solve the problem ..... plz reply.
I've attached a screenshot of the message.
My systen configuration is :

• Intel Core2duo 6750
• Intel original motherboard DG33FB
• 2 Gb 667 Mhz RAM
