Norton Antivirus 2008 is a full featured antivirus and antispyware product. It includes several options that are commonly passed over by other suites while leaving many out that would be beneficial. The Norton scanning engine is one of the most complete on the market, but suffers from issues with system resource usage and overzealous integration with your computer that can cause freezing or simple hanging application.

CA Antivirus 2008 is a solid virus scanner that works well to find and eliminate viruses. Unfortunately, this is all it can do. No extra features are included with CA Antivirus beyond the bare minimums. In many cases, this could be considered an asset due to speed increases associated with many minimalist programs. CA doesn't take advantage of this in the 2008 version which still slows your computer down all around.

Norman Antivirus and Antispyware is a solid product that suffers from some small quirks that hold it back from being a top 5 product. The scanning features that are included with Norman Antivirus and Antispyware are great as far as detection of viruses and spyware are concerned. Unfortunately, it slowed down our test computer considerably while we were performing simple actions like surfing the web or taking screenshots.
