Don't do it!

I suppose it was inevitable eventually but it still really, really annoys me...
Recently I've received a number of supposed "comments" on the blog... except they are not really comments, they are links to a so-called 'virus scanner' that proceeds to tell you how many bits of spyware etc. are on your computer and how you need to download their software to protect your computer... etc. etc.
In fact it is nothing but spyware itself. I am trying to intercept these bogus comments and delete them before any of you accidentally clicks on the links but I want to warn you anyway. If you see a comment that asks you to click "here" - please don't.
If this nuisance persists I may have to introduce comment moderation which would mean that comments don't appear until I have vetted them. I'd rather not do that but if I have to I will.
In the meantime keep the genuine comments coming. It's good to know that somebody actually reads this stuff now and again.
