I just miss typed www.blogger.com as something else by leaving one letter out. I got a warning from Avast that this other site was trying to send malware to my computer. Wow. The malware is a new level of naughty. Typo sites with advertising are very common (as are .com sites when the site people want is .gov as in the porn site which used to squat at www.whitehouse.com and the parody site which used to be at www.whitehouse.net -- the US government seems to have evicted them).
OK I typed www dot blgger dot com. Don't try this at home kids. Never count on a virus checker.
