Some good antivurus!

As you know, there are lots of anti virus softwares.You can select any of them. mcafee bitdefender norton

It depends if you're looking for free or paid versions. However, usually the paid versions of an anti-virus are better. If you have a genuine copy of windows XP, vista and windows 7, I highly recommend that you try microsoft security essentials, which is a free anti-virus software from microsoft. My current operating system is windows 8, hence it has a built anti-virus software already which is similar to security essentials, and is called windows defender. Avg, nod 32, avira, and avast are some of the good anti-virus softwares you can get.

There's a lot of antivirus that are for free. I recommend Avast for I have downloaded it before and they gave it 1 month for free and if you register they'll extend it til 1 year. I don't know it still exist now for I am using a paid one.

I use the McAfee and it is good one. Someone suggested escan and i tried it for a month and it was good too but this was a purchased one and i had a trial version. I do not know whether the free versions are good so I just buy one. Thanks for sharing and have a wonderful day ahead..

I had always trusted avast antivirus. You should try it. The design looks good.
