Have a laptop with Sniffer installed on it. And when in the office I log on as "Sniffer". But when I travel to any remote I usually log onto the laptop as myself in order to recieve Corporate e-mails and use AOL IM. My question is this: I know I should be running anti-virus software when logging on to check e-mail, and using Instant Messanger. But do I need to have anti-virus software running when logged on as "Sniffer" which does not have any thing but access to the Sniffer software?
