Reported file was from my PC archive:
bwmeterpro_setup.exe (1257323 bytes, 2008-10-06, Bandwidth Meter Pro 2.6.629 installer)
Meanwhile after posting here above I'd followed given link and redownloaded bwmeterpro_setup.zip
Then I found that the installer was renewed since my earlier download:
bwmeterpro_setup.exe (1216996 bytes, 2009-09-10, Bandwidth Meter Pro 2.6.629 installer)
And there no more 'malware' detected in the renewed installer by CIS.
So my false positive report seem to be out of date by now.
