I continually have to clean up a lot of virus infected computers owned by people who thought they were protected because they were using big-name anti-virus programmes or any one of the free anti-virus programmes that are available.
None of those programmes are capable of protecting anyone and it doesn't matter whether you walk on the wild side or not - your computer will become infected.
The only one that I'll use on my computers and recommend to customers is Kaspersky.
Kaspersky Internet Security is also available for customers who want or need a secure system and don't forget to ask me about KAV Mobile for your mobile phones that access the internet and emails.
