It started with an email from a worried satnav user, Lloyd Reid of Trichromic LLP an IT consultant who knows his way around a computer and knows a virus when his AV software flags one up. The cause for his concern being a newly purchased TomTom GO 910 satnav unit that, once connected to his PC, immediately caused an anti-virus software alert. Not one, but two alerts in fact. The win32.Perlovga.A Trojan and TR/Drop.Small.qp were identified as being resident on the satnav hard drive, within the copy.exe and host.exe files.
According to an official reply from TomTom, a small number of TomTom G910 GPS devices produced between September and November 2006, all shipped with software version 6.51, may be infected with these trojans.
TomTom claims the viruses are easy to remove with antivirus software.
