Anyone familiar with these Rundll errors?

[ssmith]

Good Evening.
On a home computer running winxp, at start up the computer shows 2 Rundll errors:

iericfs.dll
acaquibuz.dll

I cannot find any reference to either one anywhere.
My sister (not my computer, thank goodness may have deleted or removed something and this may be causing her winxp errors. Maybe a remnant of some program or even virus (?) trying to load ?
Is there a way to check and repair these rundll types of errors?
thanks for any info.

Was probably malware in the startup entries.

Thanks was thinking the same thing.
Any idea where to go looking or something to use to get rid of what is left to give the errors?
can look at msconfig and see what is there the next time I go over to visit.

ccleaner has support for managing the startup entries.
