Life in the antivirus software world is a constant game of 'catching up' because so many new viruses are released. It is absolutely crucial that you update your software as often as possible.
These days, practically everyone's online, downloading and exchanging files, and developers are in such a hurry to get their Web sites up or their files out that checking for a nasty bug is more of a courtesy than a requirement.
