That type of driver is never available as an individual download from anyone. It's probably part of the chipset driver package for your board and chipset. Can you even find or identify it on your own on your PC? Both of the dates of those drivers pre-date the existence of the P67 chipset ('06 and '08, the P67 was introduced in 2011) so that might even be a Microsoft driver. That is rather strange overall.
IMO, that sounds like a mistake or scam from AVG, as all they could do is use the chipset driver installation program from Intel, for their boards that use the same chipset, the P67. Or perhaps a Windows update? Do you have an issue you think that driver will fix? I would not worry about this at all.
