I have Windows Vista, and it came with Windows One Care Antivirus and Firewall, but I suspect they're not very effective because I got infected anyway.
Now that my system is clean, I want to use better Antivirus and Firewalls.
Is the Firewall in One Care any good, or should I get something else?
I also have Windows Defender, but it's not running - is that any good?
If I get something like Avast!, can I also run Superantispyware and Spywareblaster at the same time or do I just keep those for when I want to scan for a possible infection?
Thanks in advance for your advice,
Erica
