False Positive AMalum detection with CA Anti-Virus

Question

I have CA Anti-Virus and Windows XP with Service Pack 3 (SP3). My system keeps telling me that I have been infected with the Win32/AMalum virus and when I quarantine the files, Windows then tells me I need to replace needed system files and asks for my Windows XP CDROM. When the files are replaced, the "loop" starts over again with CA telling me I am infected! What gives?
