Not all antivirus programs are compatible with both Windows XP and Windows Vista but I recommend that you buy one that is compatible with both.

As new viruses and trojans emerge all the time on the internet your antivirus program should be easily updated to meet with new threats all the time. I heard the other year of an author who hade written a whole novel on his PC. He had a good firewall and relied on that and the original antivirus program that came with his PC from the beginning but lost his whole novel before publication and had of course, for the worse, also forgotten to make a proper backup of his work. More than one year of writing was completely spoiled. He is nowadays very eager to update his antivirus program properly and has, of course, one of the best there is on the market. Therefore, once again, I strongly recommend that you purchase a good, easily updatable Vista Antivirus program or, even better, a program compatible with both Windows Vista and Windows XP. As you probably know the later still lingers on in many computers.

But if you know for sure that your PC has Windows Vista of course such a program is sufficient for you. Remember also to beware of all the pirate antivirus programs out there on the internet that only give a false sense of protection. They often come to a quite big cost but provide no protection at all and some of them can even infect your PC with viruses.

You can safely buy the antivirus program I recommend via the link here below. This program makes sure that your PC will be fully protected from the first minute of installation. It comes with different prices according to if you choose one or two years of updating services. My own and several collegues PC:s have this program installed since more than two years now and we are all very satisfied with this program. So do not wait, put your order right away through the link below!
