At first sight F-Secure's Health Check 2.0 seems a useful addition to a PC owners' box of troubleshooting tricks. It is OK, but it is nothing to get excited about.

The online application is a Java program. Itworks with Firefox or Microsoft Internet Explorer to check a computer's security status then reports on potential risks.

On the plus side it is free, quick and simple to use. The code loads directly from the Health Check web page and after the fuss of accepting terms and conditions it takes next to no time to download even on my erratic broadband connection. I clocked the first download at seven seconds.

Once leaded the software steps through a familiar wizard-style process with four stages. The first stage is automatic. It checks you have anti-virus, anti-spyware and a firewall installed and up-to-date.

The 'next' button moves things along to stage two which investigates back-up – we'll look closer at this in a moment. Stage three checks key programs are up-to-date. The last stage is a summary screen with links to 'solutions' to identified problems.

Even if everything was perfectly hunky-dory, which it isn't, PC Health Check 2.0 is of limited use.

For a start alternatives do the same job either as well or better. For example, Secunia offers the free Online Software Inspector and the more complete downloadable Secunia Personal Software Inspector.

But my big problem with Health Check 2.0 is it is mainly a crude promotional device for F-Secure's products and services. It's compromised by its commercial function.

My computer failed the second stage back-up test. The software told me it didn't find any back-up. This is wrong. There are three back-up applications on my computer. I back up regularly to an external disk and to a server.

When I clicked on the Health Check 2.0 'solve' button to troubleshoot the 'problem' found by the software it told me I could protect my "valuable content" with F-Secure Online Backup. And gave a link to the F-Secure store.

I live in New Zealand. My computer has almost a terabyte of data. I'm theoretically on an unlimited broadband plan, but with shaped bandwidth for almost the entire working day. In other words, online back-up isn't realistic. And yet PC Health Check tells me it is.

If the application gets this advice wrong – what use is the rest of its information?

Lastly, when the program finishes, there's the opportunity to register an email address with F-Secure. Now why would I want to do that?
