Below is an HDB signature for more malware on behalf of Russia designed to infect computers of the Baltic countries and Poland.

Copy the signature(s) and post to a new Notepad or similar text writer file, and save it in the ClamWin database folder as a file named Sigfile.hdb with a file type of “All Files”. Do not save it as text file. The file name should end in nothing but .hdb. The date and time are the last two items in the signature.

For multiple signatures, put each signature on a separate line in the Notepad file. You can add multiple signatures to the top of an existing HDB signature file (just add one blank line and paste the signatures there—any lines needed will be added). Adding signatures to the bottom of an existing signature file always gives me a scanning error. Delete any blank lines between signatures in the signature file after pasting and before saving.

After you save the signature file in the ClamWin database folder, scan something with ClamWin to make sure it works. If you get a scan error, delete the signature file from the database folder or delete only the signatures that you just posted to an existing HDB file and resave it. Leave no blank lines in the signature file.

Delete signatures after they are 6 weeks old. The viruses will be updated by then.
