well, i agree with roddy on this, norton is a ''love/hate'' situation. i have had norton, unlike roddy, mine failed me after years of loyal service subscibtions from me. i had since then used AVG and found that it is less of a resource hog, free, and does the job just as good as norton. it updates on a regular basis, has great email protection and real time protections as well. you can find the link to that and another popular free choice, Avast!. i have had that one in the past and it was a toss up between Avast! and AVG, well, AVG won. but if you like Norton, and do want to pay for all that you recieve, then the choice is yours. it's just that i am one of those ''haters'' of it and never will i go back to it. good luck a nd surf safe.
