For Helen

To check your computer for the DNS mailware that is supposed to hit July 9, go here

http://www.cbc.ca/news/technology/story/2012/07/06/tech-dns-changer-virus.html

and click on the link they give.

You agree to the terms and then it runs a check that only takes a couple of seconds.  If you are ok, the banner will be green.  If not OK, the banner will be red and there will be a link to fix the problem.

I think any new computer will be ok.
