I'm posting something that I read a while back in a computer magazine. Since it's summertime and many are away traveling. When you get back home and turn on your PC that has been off for over a week...stop and give your antivirus program a chance to do its updates----BEFORE you quickly log into your email.

Virus are created daily, if the computer hasn't been on for days then it cannot protect you from any new viruses out there because it has not updated itself with the latest tools.   Be patient and let the virus protection grab the latest definitions, then open your email. This way if something suspicious is in your email the virus protection will have a chance to identify it and neutralize it since it has the latest updates!

Hope everyone is having a great 4th!
