Virtualbox 3.0.6
Host: Ubuntu 9.04
Guest: XP Pro SP3

I just created a VM and installed XP Pro SP3. Then installed Spybot Search & Destroy with it's resident TeaTimer watchdog. I installed Guest Additions and at the completion when it asked me to reboot the VM, Spybot popped up and identified VBoxDrvInst.exe as the DyFuCa.InternetOptimizer trojan.

C:\Program Files\Sun\VirtualBox Guest Additions>dir

Volume in drive C has no label.

Volume Serial Number is 0496-E8F2

I assume this is a false positive?

Thanks.

Yes, it's a false positive. There is no virus in the GA. Else my own antivirus would have triggered something (AVG and Comodo).
