I have an windows XP pc. I noticed if i leave the PC on for a few days, it catches some viruses. is this possible and is it better to shut it down when not being used.
Do i need any security software for viruses and trojans and firewalls anda registr cleaner software.
or would the windows firewall and combofix and hijackthis and malaware would do the job free of charge.
what do you usually recommend.
