Windows XP Pro SP2-couple of questions about AVG read out?

Was wondering if anyone has an idea of what it means when you run AVG Antivvirus and the first thing it checks is (see below and they all have change after them, what does that mean?
Partition Table (MBR) change

Then toward the bottom it has
wsock32.dll change
user32.dll change
shell32.dll change
ntoskrnl.exe change

why does it have change there? I ran sfc /scannow and it said it needed a couple of dlls I put the disk in and let it take what it wanted and now ran avg again and it is the same.

It was running really slow and and he was having problems with the internet, when he was on a web page and would click a link it would open up his my documents folder he said, I looked at it and it was taking forever to get to a web page so I set the servers to the right ones for his ISP and then ran the netsh winsock reset and it seemed to run much better but not great, ran Ewido and caught 400 and some items but all tracking cookies got rid of them.
Spybot was clean
Windows defender is clean
he has ie-spyad
spyblaster
spywareguard
winpatrol
AVG

His hijack log looks ok to me but I am not good at reading them here is his log
