Do I Need Antivirus Software on my Laptop??
In a word, YES! Even if you have a Mac.
Having updated Antivirus Software helps protect your machine from becoming infected with Malware, and also helps stop your machine from infecting others.

The choice is entirely up to you. Paid versions usually include extra features such as firewalls and web-filters. These offer greater protection, however there are several free software products that do a reasonably good job. Some good examples are provided below:
