if Google can scan the entire internet, just for me, and find 149,000 entries for Locost in just 0.04 seconds. why can't they do a virus scan in it at the same time?

Or am I missing something?

their computers constantly search the net, they just tell you the results quick! Hence they have a good portion of the internet in their cache.

So why don't they spot the viruses?

im no expert, but viruses arent visible like web pages. They are either on home PCs, which google cant usually look through, or being sent by whoever sends them.

From what I understand (which is very little) "The Internet" takes 2-3 months to update. New virii(us's) are produced on a daily basis so keeping track is futile.
