Moreover the free version (v.8.5) does not allow users to schedule updates as they like. Updates are scheduled only one time at the start-up or can be done manually.
Updating any antivirus program with latest virus definitions are must for continued protection. In the case of AVG, this is possible by doing updates more times a day.
However, as a manual operation, this is not being done usually. Moreover, it can also occur that at the start-up, internet connection is not active and, therefore, the Anti-Virus remains out of date until users do update manually.
AVUS (Anti-Virus Update Service) is a small utility for Windows working in background, which does scheduled updates to the virus definitions of the well-known AVG Free Anti-Virus 8.5.
Basically, it executes a temporary batch file every certain amount of time invoking AVG Anti-Virus to do updates.
Works on Windows XP, Vista and 7 (required .NET 3.5). Download AVUS (Anti-Virus Update Service)for AVG Free 8.5 (96Kb)from Sourceforge.
