Anti-Trojan Edit

Before the rise of Anti-spyware, anti-trojans were generally considered the second line of defense after anti-virus. They justified themselves with quality memory scanners, better cleaning abilities and greater focus on none-spreading malware like trojans. Despite this, even at their heyday, there were never very popular and only a handful anti-trojans exist. Just like antispyware, the freeware versions are generally on demand scanners only.

Today, the focus is on antispyware. Besides the line between antispyware and antitrojan is very thin anyway. BoClean (classified as a anti-trojan) has always handled malware that we call spyware. Ewido has gone through many name changes, starting off as an anti-trojan, before changing the name to anti-malware , currently it goes by AVG Antispyware.

You can probably just go with BoClean for real-time protection if you see the need.
