Dear Sir, I've download AVG Antivirus Free Edition 2015. And Install it After installing I've Update it.. After 7 days later it again want to update ...i'veupdater it again..Is there any solution to activate it for a year without update

Monjur, The updating of AVG is a vital part of its operation in the fight against viruses. Virus database definitions are usually updated @ least once a day & program updates less frequently. If you look @ this link (https://support.avg.com/answers?id=906b0000000D48VAAS) you'll see that the last 2 program updates were actually a month apart. Updating just once a year is quite obviously not a practical proposition with the operation of AVG.
