Take one look at the box and you might think that Christmas has come early.

Not only does CA Internet Security Suite Plus contain just about every type of security software you think you might need, it works on three PCs and promises to pay you up to £2,500 for any damage that's caused through virus infection after it's been installed.

Poorly integrated tools

Sadly, expectation doesn't live up to reality. There are plenty of tools offered in the suite, but none of them can claim to be market leaders.

Take the anti-virus and anti-spyware tools, for example. The lack of integration means that you have to scan your PC separately for malware using each tool, and while they prove adept at removing infections that are already there, they're less reliable when it comes to keeping unwanted software off your system in the first place.

AVtest.org discovered that the suite performed incredibly poorly in the real-time protection stakes, with nearly one in four malware samples slipping past its defences.

Solid firewall

Things improve slightly with the firewall, which is far more robust than the version bundled with the 2007 release.

Despite this, it lacks the user-friendliness of Norton and Panda, throwing up alerts left, right and centre.

If you're prepared to put up with that kind of hassle, you'll get better results installing the free Comodo Personal Firewall tool - and at least its alerts give you more helpful information.

Unreliable malware filters

The box promises an anti-phishing filter, but the technology behind its Website Inspector is outdated.

We tested it with recently reported phishing sites from www.millersmiles.co.uk and it rated them all - after a period of considerable time - as low risk. Thankfully, IE7's built-in phishing filter had already blocked them, but clearly CA's tool is not to be relied on.

The anti-spam tool also lacks sophistication, relying on a white-list of trusted emails based on your contacts list.

All other mail is filtered into a spam folder and it's up to you to go through this, picking out the valid emails from the unwanted ones. This is fine if you don't have many friends or contacts, but tiresome if you regularly receive legitimate mail from new or unknown sources.
