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.
Mydoom.G is functionally similar to the original variant but it contains this hidden message: to netsky's creator(s): imho, skynet is a decentralized peer-to-peer neural network. we have seen P2P in Slapper in Sinit only. They may be called skynets, but not your shitty application.
Apparently, the author of Mydoom wanted to send a message to the authors of the Netsky worm:
The executable is packed with unmodified UPX, and a minority of the strings are scrambled as in the first variants of the worm, using the old fashioned ROT13.
The emails sent by Mydoom.G will contain one of the following subjects:
It might additionally contain any of the following:
to the subject.
Message bodies are chosen from:
The attachment filename will be composed from combining the any of the following filenames:
and the following extensions:
The worm will go through all the machines' drives and folder on them and performing the following actions on the found files.
Mydoom will harvest email addresses from files with the extensions:
If a file with extension PIF is found, it will overwrite 8 out of 10 times.
If the 'target' file has an extension among:
With a probability of 95% it will copy itself to a filename with the same name as the 'target' file, plus an the extension 'EXE' 8 out of 10 times and 'SCR' otherwise.
Mydoom.G will attempt to launch a DDoS attack against Symantec. When performing the attack, it will try to connect to either symantec.com or www.symantec.com. It will launch from 8 up to 77 of threads, requesting Symantec's main page.
