Scan after each update

I want to share a habit which can't harm you but can save you lots of money and irritations.

Scan the computer after each update.

Some time ago I updated a very trusted program, but my cmputer started to act weird.
I disconnected from internet immediately and scanned my computer.

My children told me I was nuts, as I scanned the computer right before the update.

I was right to do so, though.

Turned out someone mimicked the update graphic of the trusted program so well, that I took it for real and downloaded a nasty computer animal.

My scanners caught it and destroyed it. Pffff.
