Best Anti-virus

My friend Rezvy or Sohel always ask me which is the best antivirus. I always told them about avg 8.5. But now I realise tha all antivirus are best if they are updated regularly. I am giving some name of ativiruse which are used by me.

1. Eset NOD 32 *****[Now I like it very much]
2. AVG 8.5 ****[It always detects *.exe files]
3. Avast Antivirus **** [Sometimes it doesn`t detect virus]
4. Kaspersky antivirus
5. Avira antivirus free **
6. Mcfee[Its not too good]

Now I am using Eset NOD 32 antivirus. I will give you a update of nod32 usernames and passwords.
