My anti malware software "hitman pro" uses heuristics to highlight suspicious files. It is highlighting the following three, all within c:\windows\system32
mpcdx.ax rlapedec.ax rlmpcdec.ax
Hitman pro has never complained about these files before. I don't know if that's because they're newly added or newly modified.
Should I be worried?
P.S. I recently installed erightsoft's "super" program.
