Hi, I'm a newbie to this forum, this is my first thread, and I want to start by saying how much I've learned by going thru previous threads. It's a massive amount of knowledge! I've recently been forced to update my knowledge on security threats and counter-measures. I'm trying to clean a computer that has been "infected" by spyware, but I do have some concerns about the computer also being infected with other types of "malware". In short, I've decided to clean it thoroughly. In order to clean it, I've identified different threats and searched for tools/procedures to find these threats. In order to find trojans I'm using TDS-3 (and KAV 4.5). To find rootkits I'm using "Haxorcitos Console Tool v0.3" among others. (It's freely available for download at: I have removed the link for review as it may be against the TOS Pilli Kaspersky 18.104.22.168 identifies Haxorcitos as a trojan of type "Backdoor.Small.AO". TDS-3 gives me no indication that anything is wrong. Please help me understand this. P.S. Just to clarify, I'm under no illusion that ANY software can find everything but I want/need to understand the strength and weakness of the tools I use.
