There's this Norton anti virus am using but it keep telling me to update after 4 or 5 days of the previous update. But the problem was that I became fed up with it since I don't have frequent access to internet which made me lost it's activenesss. Please suggest anti virus that I can only be updating on monthly and not weekly basis and the source. Thanks.

Same here!

Most Anti viruses are good, depends on how you look at it. The effectiveness of an AV or Internet Security lies on the regular updates of its Virus Definitions, which depends solely on the availability of Internet. You can turn off the Auto Update of your Norton AV, and be downloading off line DAT files, monthly to run your updates.
