Avast update, "Invalid file signature. Setup will terminate"

Hi I was playing my games when avast popped up in the corner telling me there was an update so I clicked on it and started it up after a couple of minutes i looked back to see where it is at and it gave the message, “Last encountered error: Invalid file signature. Setup will terminate.”. I don’t know what to do because I’m afraid to go to a lot of websites now because I feel like I can get attacked. I’m running windows 7 64bit, if anyone can help me I would really appreciate it. Thank you.

I’m also having this problem and also getting a little wary of browsing.

Also the same error.

Do you guys get streamed updates?

In that case everything is fine.
