Summary
Monlater is a trojan that detects AppServer.exe processes and uninstalls a package with certain UID from an infected device.
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
Monlater.A contains a function that allows it to detect AppServer.exe processes and uninstall a package with UID 0x20042EB8 from an infected device. Similar functionality is also found in a later variant, Monlater.B, but uses a different file name and UID.
Upon further inspection, samples in the Monlater family show a lot of similarities with those from another family - Monsoon, which was discovered in early 2011. It is highly likely that Monsoon and Monlater connect to the same command and control (C&C) server. The same update channel may also have been used to push new versions of malware and hide the original ones to avoid detection.
