I have used Kasperaky for about a year now. It has done its job. At work we use symantec which is good.
I can't remember the name of the virus protection that comes on as a pop up virus wanting us to buy thier plan. Twice I have ran a full sweep and no viruses were dectected. I just X it out.
Ditto on what fest3er says. I for one do not click on every thing that I find in a search and I still get a hold of bugs.
10 years from now I predict we will look back and laugh at how freely the internet rip off and villians were allowed to roam. I'm not for more gov intervention, but the trash on the net is just that.
