In order to update your antivirus you do not necessarily need to call the avg support phone number. However, a number of people do call the avg tech support number when either they need advice on how to install the antivirus program for the first time or when they need the antivirus program updated or reinstalled. There are other reasons too why people contact the avg technical support phone number like when they face certain issues but these are usually the most common reasons for contacting.
Actually though, it is necessary to update the antivirus software as an old antivirus program may not offer you the complete protection that you need from internet attacks. The computers are continuously bombarded and are at risk as there are new malware which are out every single day. In order to ensure that the computer is completely safe, periodically it needs to be updated so that all the information which is needed to fight recent threats are available.
Updates are important because when a new virus is released, the old antivirus protection gets outdated. Some of the spyware and viruses hack the system and corrupt or even erase the data on the computer. They are even known to lock the information using a password that even the owner is not aware of it.
Incase your computer is infected, there are chances that you pass this along to your friends and family as well as all your contacts through network links, flash drives or even emails.
Incase you have installed an antivirus program and turned off the automatic updates you will be living in a false state of security whereas the computer is still open for attacks and vulnerable to various threats.
Virus protection which is updated keeps you well prepared in the ongoing war against all kinds of malware.
