Have have downloaded this program to see what it is about. It appears to monitor programs opened from emails and I believe ones from web pages but not programs that are already present or installed by other means. It does offer protection that virus protection programs can't but its value is limited (and as been pointed out, it is likely to report legitimate operations as being breaches in security) and it is not a substitue for good AV software.

Really and honestly apart from the AV software, the best protection with the likes of email attachments and unknown content on the internet is not to open them in the first place unless you know what they are.
