There is nothing like the best. each has its own advantages and disadvantages. one may be good at stopping viruses, and another at detecting malware and spyware. therefore, there are different sw for each use etc. However, my personal exp. is that in paid, Norton is good a all rounder, and in freeware AVG is good.

Sabhi achhe Hai, Sab Ki Apni ek alag Quility Hai. wo Toh User Ke Mind Par Depand Karta Hai Ki wo Kise achha Kahta Hai. Mai Mc Cafe Bhi Use Karta Hoon Aur Norton Bhi.. Company Ke PC Me Humne Quick Heal Dala Hai. wo Bhi achha Kaam Karta Hai.. Is Liye Kisi Ek Ko Achha kahna Muskil Hai Roma Ji
