Hello,

I just uninstalled Farcry 2 (After finishing a version installed from legitimate DVD-ROM) through the Control panel on VISTA 32-bit. After the uninstall finished successfully, my Comodo firewall blocked a setup.exe file from initiating a 'buffer overflow attack' on explorer.exe from that setup.exe.

The setup.exe was digitally signed to Ubisoft according to properties, so I allowed it, then got a Comodo popup saying it was blocked and advising me to terminate the exe (explorer or setup.exe, I'm not sure which - explorer didn't visibly terminate afaik). The action in Comodo logs was a 'shellcode injection'. I don't think I'm infected as such, but can't find anything relating to this on the web - can anyone tell me what happened here or advise on what to do? I'm running virus-scans now but I'm a tech-noob and would appreciate any help. Apologies if I've posted in the wrong place, not sure where this issue goes tbh :-(

Thank you.
