The Experimental virus was found in Spain in December 1994. It's a fast infector of COM and EXE files, infecting files when they are accessed or executed.
Experimental is a full stealth virus; the changes it makes to programs are not visible as long as the virus is resident. The resident part of the virus occupies approximately 1784 bytes of memory. Infected files grow by 1617 bytes.
Experimental activates on the 24th of Janyary on any year. At this time it overwrites the start of hard disk and displays the text "Experimental v".
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.
