Protecting yourself

  • Use strong passwords(opens in new tab) and activate two-factor authentication
  • Update your apps and programs regularly (software/firmware updates)
  • Install professional antivirus software
  • When you receive e-mails, look out for fake senders, impersonal forms of address and spelling mistakes

Just one click on a false link or e-mail attachment is all it takes to add malware surreptitiously onto a device. Once there, it can delete or change files, manipulate security settings or collect confidential data, without the knowledge of the device owner. It is therefore important to change all your passwords once the malware has been cleaned up.

The free spam filter

Swisscom protects its customers from dishonest mass advertising using the spam filter for e-mails, the Callfilter for calls and the SMS filter(opens in new tab) for text messages. These services are free for Swisscom customers.

How the spam filter works

The spam filter checks all inbound and outbound e-mails for typical spam features, such as dangerous links. If an e-mail is suspicious or flagged as spam by multiple recipients, it is sent to the spam folder. You can activate or deactivate the spam filter at any time in My Swisscom(opens in new tab).

If your e-mail is sent to the recipient’s spam folder, it was probably classed as potential spam by the e-mail provider. Make sure that your e-mail does not contain any links, signatures or images that could be flagged up as spam.

If your e-mails are being classed as spam, try creating a new mail rather than editing it with the ‘reply’ or ‘forward’ functions. Otherwise, the previous e-mail communication will be included in the e-mail, making it more likely that your e-mail contains a typical spam element.

If multiple recipients flag a genuine newsletter as spam, it may be sent to the recipients’ spam folders. Genuine newsletter senders include an unsubscribe link at the foot of the e-mail or an address for requests to unsubscribe. You should unsubscribe this way if you no longer wish to receive a newsletter. If an e-mail is sent to your spam folder in error, you can mark it as “not spam” in Bluewin Webmail.
