ZoneAlarm by Check Point, firewall, antivirus and antispyware is tool that I use for quite some time on one of my computers. It offered update to new version 7.0.462.000 today. After installation and starting antispyware scan it detected and considered Windows Live Messenger as Trojan with medium risk. ZoneAlarm recommended that I should “delete this application immediately because it constitutes security and privacy risks, and has no known usefulness”.
Here is screen shot (censored because of privacy reasons):
ZoneAlarm offered options to quarantine, delete or ignore it. After I selected delete it actually deleted Windows Live Messenger!
I reinstalled messenger, scanned again for spyware and same situation repeated. So we can now say that Check Point firmly considers Windows Live Messenger as Trojan. Some people will say: Not to far from truth, isn’t it? 🙂
Hopefully Check Point and Microsoft will solve this in mutual talks and confirm messenger as safe software.
