Virus checking options

Microsoft Office macro settings

3. Norman Virus Control also allows you to block Office documents that contain macros. You can select one of the following options:

Do not check macros (not recommended) - This option will cause GFI MailSecurity to ignore macros and just rely on the anti virus engine to check for new viruses.

Block all documents containing macros - This option will quarantine all Microsoft Office attachments that contain macros.

Blocking word macros

It is highly recommended to quarantine all macros. This will effectively protect you 100% from any unknown macro viruses. Some macros are not viruses, but macros received via the Internet are highly suspicious.

Of course the Virus engine will check for known viruses, but new email viruses can spread so fast that your system can become infected before the virus signatures has been updated. (This happens with all anti virus engines).

In addition, malicious hackers, could use a custom made macro embedded in a word document to attack your company to install a Trojan or obtain confidential information.

4. The section in the general tab displays the scanning engine version as well as the date of the current signature files.

Virus updates settings

Virus updates settings

You can set-up virus update settings from the updates tab. To enable checking for updates, ensure that the `Automatically check for updates option is ticked'. You can then choose to automatically download the updates or just be notified when new updates are available. You can specify the interval under the `Download/Check every:' option.

Triggering the virus update manually

You can trigger a manual download of the virus updates by clicking on the 'Download updates now' button.

Update options

General update options, for example download mode and download location, can be configured General > General settings node in the MailSecurity configuration. For more information on general update options, please see the General Options chapter, paragraph update options.
