Because the feature set is so similar to the 2007 version of CA Internet Security Suite, I'm going to refer readers to my BrightHub review of that product for more in-depth details. I'll say a few general words here by way of overview.
CA's Internet Security Suite is made up of seven separate computer security products that cover everything from antivirus to anti-spam tools, as well as a firewall and settings migration and parental control tools. The tools are generally easy to understand and operate.
Many of the tools integrate with CA's online resources and provide a healthy amount of feedback to the user. The system tray icon exposes a helpful amount of control over the applications, including the ability to snooze the virus protection and instantly turn off all access to the Internet in the event of an attack.
The virus scanner detected the virus in both the Eicar COM and text files and quarantined both. I also was able to click a hotlink in the detection dialog box and it took me to CA's online report about the virus, which gave me important threat information about the virus. The included toolbar add-in also verifies sites and downloads with helpful feedback.
The spyware scanner also detected the Spycar test threats handily, though the performance was very sluggish. The pop-up gives the user a chance to respond to the threat, but after about ten seconds will disappear and prevent the threat from affecting the computer.
Overall, Internet Security Suite Plus 2008 is a well-rounded package for the general home user. It comes with all the computer security tools the home system might need and functionally performs as expected (though the speed is less than optimal--see the Performance section of this review).
While the virus scanner in the 2008 version detected the Eicar test files, it allowed me to run the COM file before it presented me with a warning dialog box. Other scanners detected the virus before I was able to launch it and stopped me from running the file. While the Eicar virus is innocuous, other threats are not, and I think the scanner should have prevented execution of the file.
