Panda Antivirus Pro 2009 is advertised as providing anti-virus and anti-spyware protection for both files and executables, and also for email.
Like many anti-virus programs, it also contains a firewall to shore up Microsoft's offering.
Usefully, the installation process includes a full scan of the whole computer using the default definitions before the installation begins properly.
This process found eight infections, which turned out to be nothing more than cookies left by previously surfing to other security vendors' websites.
Panda Antivirus also scans for un-patched security holes in Windows. This will show you better than anything else that your PC is at risk. A Windows Update button means you have no excuse to put off installing your security patches.
Unfortunately, it detected the spyware as being adware and missed the real adware completely, which meant it lost marks. It did correctly identify our polymorphic virus, however, as we'd expect.
