How are you
?
It detect js ( java script ) object too ( malicious iframe I don't know ).
Doing well. Maybe if you can discover the temporary folders of Email clients (where the emails and attachments are stored) and including those folders in this Temporary folders rule, it will possibly make Comodo AV filter emails as well.
I think I am going to suggest for Comodo to include by default the rules you mentioned in the other post. Comodo AV should scan the contents of all browsers by default, even more if it have the capability of doing so just by adding a rule that points to a folder.
Also to have this object scanning working in Sandboxed Firefox, the Comodo AV needs to be at "On Access" mode.
