Free antivirus

Someone, let's call her "Hayley", asked about free antivirus software.

Well, as you might have read there are a whole bunch of "dodgy" free antivirus software around. So, as always, be careful what you're downloading!

What is certain, though, is that you need antivirus software and you need to keep it up to date. But you also need to take a lot of care where you go on the internet and what you do there.

A couple of half decent free resources, then would be:

AVG Free or Avast.

I've used both and they're both OK. If you really get a real problem then Sophos has a free 30 day trial. It's expensive to sign up for the full version, but if you need to get out of a problem then Sophos might be the cure if nothing else is working.

Of course, you'll also need to make sure to check for spyware, malware and all the other nasties.
