WHY ANTIVIRUS ENGINE MUST BE UPDATED
Because the virus maker - hacker - always upgrade and update their viruses. When virus definition in antivirus engine is obsolete and you did not update it, your antivirus engine become useless/can not clean and delete virus from your PC/system. And the updating antivirus definition is the better way to protect your computer.
YOU CAN USE FREE ANTIVIRUS ENGINE
Paid antivirus engine , we know must be better than free one, but free antivirus engine is better than NO ANTI VIRUS in your PC/system. You can download in this website - ANTI VIRUS LINKS - also for updating (virus definition) too. You just install it in your PC and getting protected. Update Dayly - online from internet if you can, but weekly is not bad idea, at least you update it once in a half moth.
Thanks A Lot
