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
When an infected file is executed the virus goes resident in memory, decreasing the amount of available DOS memory by approximately 2300 bytes.
All COM files that are executed or opened (for example, copied) will be infected by the virus. Infected files grow by 1129 bytes. This change in file size is not visible when the virus is resident in memory. The virus does not infect EXE files that have been renamed to have COM extension.
The virus is encrypted with a 8-bit key. Underneath the encryption the following text can be seen:
