staring Windows Starter 2010 causes virus

When I open the Windows Starter 2010 to start a new blank page with text, it immediately detects a MALWARE on file: R:\140066.ENU\OFFICE14\OFFSPON.EXE which causes me to reboot the computer to take away the malware file(the same one every time)
I am using the AVG virus program which takes it away..but why do I keep getting the virus alert when opening the Windows Starter 2010 to enter new information?

offspon.exe is the process that displays the rotating advertisements in Microsoft Office Starter Edition. It is a legitimate program, but because its sole purpose is to display advertisements, AVG may detect it as adware, and display a warning. Even though it is indeed a form of adware, it is 100% non-malicious and harmless, so it is safe to tell AVG to ignore it. Add it to the exception list in AVG

Stop using AVG and use MSE

Thanks....problem solved
