Updating avg antivirus manually
Although you can manually update the program, AVG Free Antivirus has auto-update options that enable you to automatically schedule the program to install any available updates and the latest virus definitions on a daily basis. Click the "Enable This Task" check box and then select the time that you want the automatic update schedule to run every day.
The file comes as a setup installer so you just need to run it and the updates will be installed, make sure to get the correct 32-bit or 64-bit version for the operating system Bitdefender is installed on.
No matter what it is you do with your computer, it is very necessary that you install an antivirus to help protect the computer against malicious applications and virus.
I am not going to be rating antivirus here because I believe that the type of antivirus one uses depends on what he/she does with the computer.
Offline users have to download virus definitions manually and then they have to update their AVG Anti-virus.
Since AVG Anti-Virus Free edition comes along with Anti-spyware, a lot of people consider using it.
