What must be on a computer? Obviously, and AntiVirus!!!

But, which is the best?

Well, after my tests, I choosed this one: Eset NOD32

It is very little in your memory, it can integretes itself in any mail program and Office program and can cooperate with any firewall installed on your pc.

It is a really really fast Anti virus software and dislike other anti virus, it doesn't slow down your computer! In the web there are many antivirus, many of them are great, but are too huge and too slow. Nod32 is fast, and can really secure your pc.

These are my classific of Anti Virus Protection Software:

Eset NOD32

Kaspersky Antivirus

Symantec Antivirus
(yes, symantec, it is very heavy, but it does very well its job!!!)

AVG Anti Virus

McAfee Internet Security

And other, but the above ones are the best of my exerience. Many of them now are included in All-In-One suite where you get antivirus, firewall, antispy... etc etc, that are very usefull to whom doesn't want to think at what they are doing and let the program correct every their wrong steps! Those suite are really heavy, and slow down your pc, your connection and you life! But you are free to decide, so choose the best that fits your needs.
