For a while now I’ve been using Messenger Plus which is a nice addon to messenger for Windows. However today via a helpful automatic update it installed some nasty spyware and an obtrusive IE toolbar for some websearching firm which no matter how many times you switched it off, it would reappear. After a half hour of trying to gain control an uninstall of Messenger Plus had sorted it out.
I then ran an ad-aware scan which removed a further 130 (bloody hell) nasty spyware entries on my machine. You just can’t surf safely nowadays. Thats what I get for not using Firefox more, now my default browser.
