What is the best anti-virus / anti-spyware software?
A. I’m sorry, but there really isn’t a “best” one. It is an ongoing war between the virus / spyware makers and the antivirus / antispyware makers, with new challenges every single day. There is no single software that can guarantee it will stop all viruses and spyware all the time. It just doesn’t work that way. Your best protection is to keep your antivirus and antispyware softwares updated and running, and to be skeptical of everything and everyone when online. For antispyware, it’s a good idea to have more than one software. A main one you use every day and a backup one you can scan with if you suspect something has gotten through your main defenses.
