rundll error-paretologic

helping a friend     he has 6yr old dell  xpsp3     started getting error loading-rundll at shut down.   c:/progfiles/commonfiles/paretologic/UUs2/UUs.dll        bleepingcomputer xp help forum-disable scheduled task-done and fixed.  looked in progfiles and common files plus add/remove in contol panel-could not find paretologic.   mbam or kas  do not detect it from looking at dds logs in mal remover threads at bleeping.  googled it-seems legit. my friend has no idea where it came from or how long it has been on his machine.   has anyone heard of this program and does it come bundled with another?       thanks
