I just had a hack attempt via a Facebook friend's compromised account. He sent me a link to a malicious YouTube lookalike site. After noting a few warning signs, including that the URL didn't tally, I went into ZA advanced settings to add a rule to block the IP address. The link the hacker sent led to ~~snip~~ address I entered to block as both a source and destination IP address. My problem is that when I tested it, it didn't work. Firefox still had no hesitation in going to that site. Anyone got any ideas what I might be doing wrong?
