Summary
Trojan:W32/AntiAV attempts to send information to a remote server.
Removal
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First, check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.
Technical Details
This malware is distributed in a RAR archive file attached to an email message.
The archive file contains an executable file which may be detected as either Gen:Trojan.Heur.RP.Mq0@ayDoNAeb or Trojan.Win32.AntiAV.iup.
Installation
The executable file uses the icon of a Microsoft Word document to appear legitimate. On execution, the malware will drop a clean Word document and open it for viewing, to further deceive the user.
Meanwhile, the malware will create a registry launchpoint so that subsequently its file will be automatically run at every Windows startup:
- HKLM\Software\Microsoft\Windows\CurrentVersion\Run common = (path of the malware)
Network connections
Once its file is active, the malware will attempt to connect to:
- tokyonews.edns.biz
- tokyoIP.freewww.info
The malware may also send information to an external party by a POST to an info.php page on a remote server.
