Virus database

This option displays the database of viruses avast! is able to detect. The database contains basic information, sorted in a searchable table.

The viruses in the list can be searched for by many parameters. If you would like to display information on a particular virus and you know the virus name, just enter the name and click Search button. If you are unsure about the name, you can use wildcards: "*" and "?" characters. The character "*" (asterisk) substitutes any numbers of characters, the character "?" (question mark) stands for one character. Example: You are searching for the Klez virus. Its actual name in the database, however, is Win32:Klez-H [Wrm]. Because of that, use wildcards: *klez*. All viruses containing the string "klez" will be found this way.

To narrow the search, you can also use three-state check-boxes next to each virus feature. The states have the following meaning:

  • Dimmed. This virus feature will be ignored during the search (virus can have this feature or not). This checkbox state is default.
  • Checked. Searched virus has to fulfil this condition.
  • Unchecked. Searched virus must not fulfil this condition.
  • Virus features
