Holar.H worm was found on 28th of May, 2003. It spreads over email and Kazaa P2P networks. The worm was written in Visual Basic and is compressed with the UPX executable compressor.
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.
Holar.H searches through '.htm', '.html', '.txt' and '.dbx'files to collect email addresses. Using its own SMTP engine it sends messages with infected attachments to these addresses.
Sender address of the email is taken from the user's default email settings.
Content of the infected emails are randomly chosen from the following list:

The attachment names are randomly chosen from a list filenames:
Hot_Show.pif Short_vClip.pif Beauty_VS_Your_FaCe.pif Endless_life.pif Hearts_translator.pif Shakiraz_Big_ass.pif Sweet_but_smilly.pif Broke_ass.pif Lo0o0o0o0oL.pif Gurls_Secrets.pif Tedious_SeX.pif Leaders_Scandals.pif HaWawi_N_Hawaii.pif Come_2_Cum.pif Tears_of_Happiness.pif White_AmeRica.pif Famous_PpL_N_Bad_Setuations.pif XxX_Mpegs_Downloader.pif Teenz_Raper.pif Real_Magic.pif The_Truth_of_Love.pif unfaithful_Gurls.pif How_to_improve_ur_love.pif AniMaL_N_Burning_Ladies.pif Aint_it_Funny.pif ToolAv01w32.pif
If the compromised computer has Kazaa file sharing client installed the worm copies itself to the shared file folder with the following names:
Hot_Show.pif Short_vClip.pif Beauty_VS_Your_FaCe.pif Endless_life.pif Hearts_translator.pif Shakiraz_Big_ass.pif Sweet_but_smilly.pif Broke_ass.pif Lo0o0o0o0oL.pif Gurls_Secrets.pif Tedious_SeX.pif Leaders_Scandals.pif HaWawi_N_Hawaii.pif Come_2_Cum.pif Tears_of_Happiness.pif White_AmeRica.pif Famous_PpL_N_Bad_Setuations.pif XxX_Mpegs_Downloader.pif Teenz_Raper.pif Real_Magic.pif The_Truth_of_Love.pif unfaithful_Gurls.pif How_to_improve_ur_love.pif AniMaL_N_Burning_Ladies.pif Aint_it_Funny.pif ToolAv01w32.pif
Using these catchy names the worm tries to bully other users into downloading and running the infected file.
When Holar.H infects a system it drops two files to the Windows System folder:
- explore.exe - worm body (with System and Hidden attributes) - SMTP.ocx - SMTP extension for Visual Basic Applications
The worm then adds a registry value to ensure that it will be started when Windows starts:
'HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\run\Explore'
Holar keeps a counter in the registry value 'HKEY_CURRENT_USER\DeathTime'. The counter is incremented every time the worm is run which is every system startup in this case. If it reaches 30 the worm attempts to delete all files from drive C: and displays the following messages in several dialog boxes:
LOVE PEACE HOME HAPPINESS These things Can't be Found as long as Bush & Jews Are aLive :) Made By ZaCker In 2003-03-30 :)
After displaying the last message box the system is restarted.
