How do i remove Win32:Mediket-B [Trj] from my pc?

Hi, Avast! has pointed out that my PC (running on Win ME) is infected by the Win32:Mediket-B [Trj], and recommended that i move the virus to chest. However, when i try, i get a pop-up message saying it cannot process the file & the same happens if i try to move/rename it. The file is a .CAD file in the restore archives, & i have no idea what’ll happen if i delete it by hand. As far as i know, I’m running the most recent version of Avast!
Does anyone have any advice please?
