Lagob.A is a simple proof-of-concept script virus written in Matlab. It infects Matlab (.m) files.
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.
The Lagob.A virus looks for Matlab files (.m) in the current folder. When it find such files, it tries to infect them by writing its code line by line on top of the file, i.e by prepending its code to the existing .m file. To avoid infecting a file multiple times, the virus uses an infection marker and does not try to infect already infected files. The virus does not have any payload or visual effects.
