My norton internet anti virus says good for 3 pc does my girlfriend from other country can used it t

I wouldn't recommend using Norton even if it came with 3 licenses. Norton entrenches itself deep inside your system making it almost impossible to completely remove. You would be better off with one of the free anti-virus products.

The best anti-virus available is Kaspersky or NOD32 (recent tests at av-comparatives.org). If you want a free anti-virus I recommend in order of popularity, but please choose the right one for you (install only one):

1. AVG Free

a. A simple interface (easier to use than Avast! and Avira)

b. Can detect about 82.82% of viruses

Cons: low virus detection

2. Avast!

a. Real-time protection

b. It has an option to delete a virus once found

c. Can detect about 87.46% of viruses.

Cons: Too many icons and confusing user interface

3. Avira AntiVir

a. It can detect malware better than Avast and AVG

b. It's cute umbrella icon

c. Can detect about 94.26% of viruses

Cons: A very sluggish update
