Thank you for your reply, but I think that it is not the real reason. Now I see the next results:
Blacklist Checking: Safe
Malicious Activity: Safe
Malware Downloads: Safe
Suspicious Activity: Suspicious
You are speaking about executable file, but checked index page have no links to this file!
Also I see the reason of detection:
Suspicious URL behaviour was detected
Suspicious Network Connections. Found by Honey Client.
What is "Suspicious Network Connections"?
About worms.exe: it is a screensaver Funny Worms developed by us many years ago. It is about 100kb in size, but is not a virus, it is screen saver for Windows written in WinAPI. It is detected only by nono-major several anti-viruses. We contacted many of anti-virus developers about this file and they removed it from their databases.
Here is a description of this Funny Worms screen saver http://www.astatix.com/fw.php
Also it listed on hundreds of websites, for example at download.com:http://download.cnet.com/Funny-Worms/3000-2257_4-10117713.html
Also this screensaver has no access to Internet, so it can't be a reason for "Suspicious Network Connections".
