Hi, I received a threat warning from Comodo firewall and it showed this file as the culprit in my temporary internet folder, with the option to clean it. Any ideas what it could be?

It sounds like you got an alert from the AV; or when using Firewall only from the cloud.

It is most likely something malicious you accidentally picked while surfing. Clean your temp internet files. That should do the trick.
