Occasionally I've gotten Trojans that NOD32 discovers right away. It seems though that my Trojan detectors/scanners don't find them though. I don't know if it is because NOD32 was locking them or if it is because they have been in zipfiles and would have needed to be opened in which case NOD32 would jump into action. What I was wondering is there any safe way to keep a trojan in a file and somehow "lock' that file so it can't do anything or is it safe in the file as long as you don't open it? I want to do this so I could test my trojan scanners. I thought of quarantine but it seems that usually I've had better luck deleting them, if I remember right it usually doesn't quarantine them when I try. I am not very knowledgeable about trojans so I don't want to experiment with them, just put them in a safe place, run some scans and delete them. And am I wrong in presuming that if a trojan is in a zip file it is harmless unless you open that file? And then if it is in a zip file will the scanners detect it or does that depend on the scanner? If this sounds like I want to go get some trojans to try it out that's not the case but I've had them before and presume I'll get them again and would like to have some idea of how my trojan scanners are working. NOD32 seems to be the only thing detecting them so far.
