Well, I have. I had just updated my firefox version to the new 3.5 and as soon as it was done installing, norton opened a window to say that my computer has been infected with the Bloodhound.Pdf.1 heuristic virus/torjan. Now I have searched a bunch of sites and nowhere explains a coherent removal process. Norton prompted me to say that it has been quarantined, but not cleaned. So any suggestions?
But they have a tendency to interfere with one-another. Specially if one quarantines some files and the other ones try to access those files (to likely do the same thing). One anti-virus One anti-spy/ad/malware One firewall (if you feel you need it) A good browser with blocking addons. Then if you do get something that your anti-virus or anti-spy/malware program can't handle, you download a couple of those super programs for a one time use, like SuperAntiSpyware, Malwarebytes, etc.
