My Anti Virus

The anti virus I use is called Avast
Avast

I really enjoy the tools and the interface it also has a feature which I really enjoy which is the silent/gaming mode.
I was recommended to use it and I have used it ever since my first download.

While reading the internet safety page I found out about some new things such as logic bombs, Macro viruses, stealth viruses and script viruses.

My experience with viruses are very little, I make sure all of my software is always up to date and I make sure I do a full system scan every 2 weeks.

The only viruses I have had a problem with myself is a worm.
