FP scan result ?

Hi guys,
COMODO made me a complete system scan and the result is quite strange for me. At first, there are some virtumonde (I have reported a few of them and you answered they are really infected). But those files are all located in unused folders (like temp and restore directories). I also tried to make another scanners and virtumonde is not installed on my system, so I have no idea where are these files coming from.
Second, there are some lines I cannot understand at all:
Heur.Suspicious@55953705 D:\MSDN6.0\Disk 1\SAMPLES\MSDN\OFFICE97\5156\VIEWER.EXE
Heur.Suspicious@22454881 D:\MSDN6.0\Disk 1\SAMPLES\VS98\SAMPLEA\REMPACKA.EXE
Heur.Suspicious@22794719 K:\download\Chipset\Chipset\32bit\2003\SMBus\nvusmb.exe
Heur.Suspicious@22794719 C:\Chipset\32bit\2003\SMBus\nvusmb.exe
The first two belong to MSDN, the last two belong to an nvidia driver.

Altogether 34 threats reported, also a sis file found (Nokia S60 symbian platform executable)

At first it would be very nice to have a link or explanation on those lines, how serious is that and so on, but it is now not a wish (it is already on the wish-list), just a comment. The most important thing is that I have no idea right now if I can believe this report, CIF itself is good enough, or just annoying.

Thanks
