I have been a rather happy user of MS Anti-Spyware ever since it came out. After getting the Zapchast trojan (which dropped an IRC client into my system), I am getting skeptical about my previous anti-malware defenses. I see that Ewido is active not only against spyware, but also trojans. Is this a realistic analysis? I would expect these to get picked up by an av, not by a spyware program. Apart from this apparent advantage, is there any other benefit from running the freeware Ewido version compared to MS Antispyware?
