I clicked on a link I believed was genuine (and it may be, if the alert is a false positive). ESS immediately shut it down. It shows the following in its log: 14/09/2012 18:21:30 HTTP filter file hxxp://skhtjo.ftp1.biz/ep/links/moving.php JS/Kryptik.XQ trojan connection terminated - quarantined X\Administrator Threat was detected upon access to web by the application: C:\Program Files (x86)\Mozilla Firefox\firefox.exe. I assume the page was not able to load thanks to ESS, but I also have NoScript running in Firefox just in case so I doubt any scripts would have been able to run even if the page were loaded. Routinely I have scanned everything with ESS and Spybot, in normal and safe mode. Nothing found. I have checked my HiJackThis log. Nothing abnormal. Is it reasonable to assume that no threat was passed onto my PC and that it is safe to continue as normal?
