When I run my anti virus program I get two lines that confuse me.

The first line under "file" says user 32.dll
then Under "result/infection" it says Change

The second one under "file" it says ntoskml.exe
And under "result/infection" it also says Change

I dont know what these are or what they mean.
The result of my scan says no infection and nothing fixed.
So I really dont know why these are on there or what they mean or if they indicate something is wrong that I need to do something?

Thanks for any help!
