the common or garden variety of the PC user (those that simply set it up and thats it) is not aware of the danger, and numbers of current virus's.
People like us, who use forums like this, or buy magazines have it hammered into them every time we log on. If we choose to ignore it, its our own fault. There must be millions out there who plug it in, surf, open every email, without any AV protection at all.
How else would they spread so quickly?
These are the people who need to be informed in the end. Here endeth the first lesson. Cheers, Whiz...
