NOD32: File scanning borked?

Goddamn warez and crack sites, those scumbag motherfuckers.

Anyway, before I open the file I make sure to scan it with my NOD32 program, so I right-click on the file and click on the NOD32 option, and it scans the file. It doesn't bring up any messages about it being a virus or whatnot, so I go ahead and open the file, and that's when another part of NOD32 pops up (AMON - File system monitor) and says, hold on there buddy, this is a trojan virus, so we've automatically quarantined it for you without actually running it.

So my question is how come the initial virus scan on the program didn't come up with any warning that this was a virus? When I used to have Norton Anti-Virus usually when I scan files it would tell me whether or not it was a virus or not, so I didn't have to risk opening the file. I'm glad NOD32 has this file system monitor apart of its program, but it does make me a little more jumpy opening suspected files. Any ideas what's going on? It's a good program though.

Seeing as how there are very few who actually pay for Antivirus software, I'm going to assume this is a cracked version of NOD32. Those cracked versions are usually ineffective when it counts, as this depends on who is the supplier and group behind the release.

How ya doing, buddy?
