I have kaspersky and the licence expires in only 2 days ...and will be un useful
Most of the experts are saying that Norton Intenernet Sercurity is one of the best. kapersky and AVG are both rated pretty poorly as far as security stuff goes.
If you are not that Computer Savvy there is also another Norton program, Norton 360, with a lot more user friendly interface.
A new PC can cost about a grand... don't skimp on protecting your investment by going with a poorly rated free program.
If you still need a free Program for whatever reason, PC magazine has said that Avast is prabably the best free program available, however rantings and raving about the new Norton system still persist.
I second AVG! I'd also suggest either AdAware or Spybot - Search & Destroy.
AVG is a FREE anti-virus program that is excellent
Ad-aware removes spyware and it's FREE!
Spybot - Search & Destroy removes spyware and it's FREE.
I would try AVG they have a free version. I've used it for years and never had a prob.
I like defender pro its cheap and it has a lot in one!
