I can't update from .492 to the latest. It always says it needs to update and it attempts to download and install and then tells me it's already at the latest (.507) when it's not. What gives? This has been happening on and off. And where do I get the latest download? When I attempt to download from the website, I get .492 which is what I already have and it won't update.
Getting frustrated.
UPDATE: Okay. Downloaded the .492 from the site (cannot find .507 anywhere). Uninstalled the previous .492 version, rebooted. Installed the new .492 I just downloaded, rebooted. It started telling me .507 was ready for download. Told it to do so. After a few minutes, it said I was already up-to-date. I rebooted just to see what would happen and nope, still at .492 and it's still telling me .507 is available.

WHAT IS GOING ON??? Very frustrating. Why can't I update to the latest version of Avast IS? I'm about ready to ask for my money back because this isn't the first time this has happened.
And why can't I get the latest version (.507) anywhere?
