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.
