Worm Issues.

Hi guys.
My problem is with a recurring worm "Win32/ainslot.a" that comes up every time the computer boots to the desktop. I run XP with MS Essentials. Essentials cleans it when asked to do so and removes it from the machine. From then on, there doesn't seem to be a problem till next time I start the computer. I have scanned with "Malawarebytes" which also finds something and deletes it. But again, its there at startup. Advise please.
Russell.

Here is the OTL Scan.
