Service Packs 2, Zone Alarm and everything is not necessary for me, I have Avast, Spy Hunter version which I pay and an outsider router from Linksys which include a firewall. They can keep all new gadgets. I had to have security due to financial transactions by Internet.
I tried Spybot and Ad-Aware and for me free softwares in certain cases, are to be used with precaution.
Yours truly!
I had to delete Spy Hunter, it was creating spywares into my computer. I am sorry to mix-up Spyware softwares and firewal softwares.
I tried Ashampoo firewall and lucky it was on a free 30 days trial, because I couldn't go on Internet. I wait 4 hours and nothing appears. That's what we call a real firewall, don't you think?
