i have a computer i use at work that uses trend office scan corporate edition for it's av. however, my work computer is often used by a few other people, and many people do have access to it. i was wondering what i can do to protect it from malware? i noticed that ad-aware and spywareblaster are only free for personal or educational use, but did not see such restrictions for spybot s&d. is this correct? can i load spybot on my work computer? maybe there is something else i can use? i am on a large network, so do i even need anything? any suggestions would be appreciated.
