Pop-up I don't understand

[Mairead50]

I have Windows XP. For a few days recently, when I moved my mouse over the
bottom toolbar on my PC, there was a box that appeared that made no sense to
me. This is what it said:
Description: Self Extracting Cabinet
Co: Microsoft Corporation
File Version 3.0.40818.0
Date created: 10/29/09 9:15 p.m.
Size: 4.70 MB
What on earth is this and should I be doing anything about it?
