Think before you click

I've been writing on technology for over a decade now but if one of these latest attacks cause serious problems I may have to throw it all in and become a consultant.

There are some basic rules that should be burned into the top of every computer monitor.

1. Never open an attachment unless you know the source personally, and preferably check with them first

2. Microsoft will never send out spam telling you to upgrade

3. If you want a patch, go to the manufacturer's website to get it

These three simple rules will get you out of the vast majority of internet attacks. Nothing is 100 per cent safe in either the real or online worlds but you could save yourself a lot of heartache and misery by following them.
