"Its value is proportional to the price & it's cheap."0.5 starson by ABall72
Pros: It is inexpensive and helps keep some of the spyware off.
Cons: It has let several viruses past it, and can't remove them. For an additional $85 fee McAfee says that they will remove them. At this point I don't trust them to do anything.
Summary: Try another brand.
