Delighted with the free version of Zone Alarm, which my son suggested I get. Amazing to see how many access attempts are being blocked! Went to a site called Shields Up yesterday, which I had bookmarked ages ago. I remember failing all the tests miserably. Anyway, this time, the results stated:
"Your system has achieved a perfect "TruStealth" rating. Not a single packet solicited or otherwise was received from your system as a result of our security probing tests. Your system ignored and refused to reply to repeated Pings (ICMP Echo Requests). From the standpoint of the passing probes of any hacker, this machine does not exist on the Internet. Some questionable personal security systems expose their users by attempting to "counter-probe the prober", thus revealing themselves. But your system wisely remained silent in every way. Very nice."
