After hbaving just signed up with McAfee, I’m now getting the hard sell for a firewall. And, lately, a computer professional friend of mine said a firewall is an absolute must for Net surfers if I want to keep a hacker from rooting through my hard drive whenever I’m on line.
For the record, I use a v90 dial-up modem. And I thought the only people who are really vulnerable are PC users who have cable modems, DSL, and dial-up modem users who leave stay online for lengthy periods.
What’s the deal here? How hard–and how probable–is it for a hacker to search through my PC while I’m online?
Any brand recommendations?
