F-Secure vulnerable to virus .jar

Everson W/ Member Posts: 23 Cyber Knight

None of the 105 sample sent to the Portal SAS had the vaccine available for virus in .jar


In Brazil we received a flood of e-mails with these malicious codes, it is necessary that the F-Secure urgent review this case because we are vulnerable to this type of attack.

    Nowadays, F-Secure doesn't work by vaccine (signature detection like the Aquarius engine). That is already an old technology.


    F-Secure uses Deepguard, which is a module that blocks malicious system modification and data access. There should be no need for specific updates for that kind of detection technology to stop new malware.
