One thing I found quiet funny, was these 2 entries in their FAQ.

Is your software a virus?

Definitely not! We don’t do anything against computer owner. If they choose to use an Goldinstall-supported service, it is identical to accepting the mechanisms we bring (such as popup advertisements). It’s just as simple as that.

So why does my antivirus classify you as trojan/worm/virus?

AV companies have a good interest in convincing you that the Internet is an insecure place full of danger, and that almost nothing is worth of any trust (unless you use their products). We don’t share such views.

So let me get this right. AV’s are wrong to detect an application that silently downloads and executes other malware? One being a rootkit in my tests, which incidentally had “botnet” in its internal PDB path.
