4. Anti-Virus
The anti virus software I use is AVG. It is a free version of a commercial software. Their paid version uses the same software engine. The difference is in the things you can do with it. The good thing is the free basic version gives you everything the average person would need from an anti virus software including live anti-virus protection.
You can find it at http://Free.AVG.com
If you also download and use Microsoft’s Windows Defender, you will have a great start to protecting your computer!
Hope this helps
