I installed this software from the CD of PC Advisor October 2007. It can be customized to install firewall, antispam or rootkit detection along with antivirus and antispyware. You can install your own preferred third party firewall which I did. After installation, the software will not update unless you register on their website.
Once registered, Avira will email you immediately a license key which will run for 90 days. This will allow you to run updates which took me quite a while to install. After updates and a restart, I performed a full scan which did not find any virus or spyware on my computer.
