I can't imagine that the guys at AVG will be over the moon with joy about this but Google's now automatically switching off the AVG Safe Search extension.
The Chrome extension plants little green ticks into the SERPs. The goal is to let you, the searcher, know that it's safe to click on any given result. Google's switched off the extension, while allowing you to override their decision and turn it back on, because it slows down the page load times.
Of course, Google works pretty hard to ensure that all its results are virus free in the first place. In fact, Chrome's a very good browser at keeping when it comes to keeping you safe and secure.
The between the lines message is clear - Google doesn't seem to think you need AVG Safe Search.
