possible malware infection with MagicJack

hi,

i have been using MagicJack voip device for a couple of months now, without any issues. yesterday, as i plugged-in the magic jack device into my laptop's usb, the Comodo Antivirus complained of a virus "Heur.Suspicious@<some digits>
in c:\Documents and Settings\Munish\ApplicationData\mjusbsp\magicjack.exe
i chose to quaratine. but now, whenever i plug-in the magic jack, get the same issue ~ hence, i am unable to use the magicjack and risk a malware's existence in my computer.


please advice me on what to do ? and give me direction to the appropriate place to seek help.

please note that in past, Comodo antivirus has complained with both SuperAntiSpyware and ComboFix. so, not sure whether this is also a spurious alarm or something to be concerned about.

regards,

munish
