A malicious program that secretly integrates itself into program or data files. It spreads by integrating itself into more files each time the host program is run.
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 detection database 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.
Bursted is a virus written for AutoCAD's embedded scripting language, AutoLISP. It replicates in a separate file, "acad.lsp" that is automatically executed by AutoCAD. It does not affect the actual drawing files.
The virus arrives in a file "acad.lsp" that is located in the same directory as the AutoCAD drawing files. When the drawing is opened, AutoCAD will automatically load and execute the contents of the "acad.lsp". The virus copies itself to AutoCAD's Support directory as "acadapp.lsp".
The virus also appends the load command to the "acad.lsp" in the Support directory, so the virus will be executed every time when AutoCAD is started. After that the virus will copy itself to every directory as "acad.lsp" from where the user opens AutoCAD drawings.
The virus hooks three AutoCAD internal commands - EXPLODE, XREF and XBIND - effectively disabling them. Additionally the virus will change the existing BURST command so that it will display the following message:
