I read that article and it's very interesting. It appears that if you are sent a random email from a friend with a link in it do not click on the link. I've received 2 such like emails from my sister who I rarely see or hear from so it was easy for me to just delete the emails.
I've told my family not to send me links or wmv files as I'm not going to open them. I hate those emails that get forwarded to millions again and again.
Thanks for the update Katya. It just goes to show that we can never be too careful.
