I'm adding Norton to this list.I bought a Gateway/Acer Touchscreen,Windows 7 (Too much sharing,in my HO),installed Norton 360,& was hacked. Ha-all of these should be on the list! So,after being told by Gateway-Level 2 that "The computer is shot", (reformatting wasn't even offered) I returned it to where I purchased it from. I then bought an HP & tried using Norton again. On it's watch,my pc was infected by 5 different PUM Hijack trojans!! After reformatting x2,I installed McAfee Total Protection...waiting to see if this will 'Protect". I also installed Anvir Task Manager Pro,& Malwarebytes.To be continued...but comments/suggestions would be appreciated.
