I got an email from a friend with a PDF attachment. The email was headed report no. 035348 and the attachment was entitled 035348.pdf. I opened it, it did not open and said error 14. I contacted my friend and they said that they did not send anything. I assume that it was something trying to put something into my computer, but my AVG 2012 free has not picked up anything. Am I being paranoid?
