But this particular laptop came with something extra. Despite the security seals being intact, and the OS having never been activated, the laptop came with a file called RavMon.exe on the C: and E: partitions.
RavMon.exe is an insidious virus that spreads on USB keys and drives, so it seems likely that this laptop was infected during the manufacturing process, despite having Symantec Anti-virus installed.
Of course, the first thing I did was remove Symantec and install ZoneAlarm, and ZA's Kaspersky anti-virus engine found RavMon.exe pretty much straight away. Thinking it was a false positive, I sent it to VirusTotal and the results speak for themselves.

Prevx info: |
Luckily, the machine wasn't actually infected, but the .exe file was sitting there waiting to be clicked. Symantec would have detected this if it had updated in time, and as it is most AV products will detect the virus.
It just goes to show that you can't necessarily trust a PC straight out of the box.
