A very simple virus from Natal in South-Africa. It was written by a student, who claims to have no knowledge of how it "escaped". This virus, just like Kennedy, will only infect .COM files starting with a JMP statement (E9). Infected programs may occasionally display the following message when they are executed.
File infected by BLOOD VIRUS version 1.20
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.
Variant:Blood-2
This variant does not really exist, as the only available sample is the result of an error in transmission between two virus researchers.
