The content of the following archived files are also being checked by antivirus:
There are two ways around this problem:
- Ask your senders to rename the attachments. You can then save them to your hard drive and rename them back.
- Upgrade to SpamStopper, then uncheck the Reject messages with dangerous attachments option at HostPilot > Mail Server > SpamStopper page. This is not recommended because you will receive all virus attachments with no filtration.
- Despite the attachment filtering, it is still possible to receive viruses in your mailbox. For example, many newer viruses are sent in encrypted (password-protected) .zip files, to prevent content and virus filters from detecting them. Even a virus filter can not filter these
viruses,because it does not "know" the password to the .zip file. Therefore, you should keep an updated virus scanner on your computer, and should be very careful about opening attachments. If you decide to open an attachment, save it to your hard drive and have your virus scanner check it before opening.
