The Best Anti-virus

i would like to say some words on antivirus.i believe that one can use any antivirus provided he/she regularly updates the program and virus definition .the problem is that people are habituated of cracks and keygens.it should never be done because it kills the talents who have developed it.the second thing is when you use a crack ,,you can never update an anivirus progam or virus defn.so,try to use a paid antivirus or free aniviruses like
avg free
avast free homeedition.
avira anivirus.
some companies also offers a limited trial period.

and i suggest if you have a little more bucks never go for jus antivirus,,buy an internet security package.they come with antivirus,antispy,rootkit,email scanner,,etc.
