virus? worm? trojan?
Theory and practial question here. My computer seems to be acting strange at the moment in that cpu useage is through the roof, secure websites gettin time out error, system start up slower than usual etc etc.
Im guessing it is virus/worm etc thats chewing my cpu etc. scanned comp with PC tools software and nothing is coming up, firewall is up and running fine.
I use WEP on my wireless (hardware issue with mulitmedia box) even though i know i should be WPA at least (alot of old people living here so figured would not be to much of a risk), so i wondering if someone has cracked my WEP, and somehow uploaded something to my computer.
How would they have uploaded something to my comp without my knowledge, and how can i guard against such things happening??
(best defence is to know there offence)
