I have been using Norton for some time on my computer and my daughter's. Recently my daughter's computer has been infected by a virus that was not detected by norton. I don't know what the name of the virus is but it changed her Internet Explorer home page to postarticles.net. Everytime she re-booted her computer, it would re-set the home page to this site. After doing some research on line, it appears this is a virus spread through windows messenger. I am currently running malwarebytes to see if I can get ride of the virus.
I am very disappointed though that Norton did not detect and remove this virus. Norton isn't cheap and I would have thought this is exactly the sort of threat I expect it to protect us from. Apparently the virus we are having problems with has been around for a while and is common so I would have thought Norton would have a definition for it.
