What is PE_FMX Virsus ?

Can anyone do me an favor and decribe this virus for me ?

Is it harmful ? Many of my programing software have been reported to have infected this kind of virsus . Do I have to remove that ?

And can I remove it without damaging my software ?


A second Question : can anyone tell me how to deal with the "Red_lof" virsus , which is typical of the two files of "folder.htt" and destop.ini ?


Thank you . Needing your help badly !!!
