Below is an HDB signature for the Acid Rain wiper now targeting certain Ukranian modems and routers that are Linux based. Even if you don't have a Linux computer, modems and routers often are Linux-based.

Copy the signature(s) 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 a text file. The file name should be Sigfile.hdb and nothing else. The date and time are the last two items in the signature.

For multiple signatures, put each signature on a separate line in a Notepad file. You can add multiple signatures to the top of an existing HDB signature file (just add one blank line and paste there—any additional lines needed will be added). Do not add to the bottom of an existing signature file or you will likely get a ClamWin 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 the signature(s) work. If you get a scan error, accept my apology, and delete the signature file from the database folder or delete only the signatures that you just posted to an existing HDB file and re-save it after removing any blank lines in the signature file.

After 4 weeks, the malware will probably have been updated, so you can delete signatures then. However, Linux signatures may last longer.
