Why Avast! Antivirus Virus Definition Update Frequency Increased Suddenly?

I notice that Avast! is updating its definition more frequently than before. I don't know what happen actually but it might be a sign of increasing threats on the internet or it's just normal updates.

However, if it's true, then you might want to be extra cautious when surfing. I went to check for few threat meters available online and McAfee Threat Meter shows the current threat as Elevated and the definition is:

An unpatched or recently patched vulnerability is present on many systems worldwide but requires user interaction to be exploited.

An existing vulnerability becomes more serious because new exploit code has been published.

There is new malware activity, but it is not widespread.

Elevated is on the second level after Low but before Severe and Critical. But, when I checked the Symantec Threatcon, it shows the risks as Level 1: Normal.

My own opinion, as of right now, we can say that it's in normal or low level but I think not for long. Maybe somewhere, someone is waiting to release something big. Just like the Conficker Worm.
