Virus protection: Surf only with an up-to-date virus protection program. Update your antivirus program regularly or use the setting for automatic, regular updates.
Firewall: Only surf the Internet with an activated firewall. The firewall monitors and checks the data traffic between the Internet and your PC. The firewall blocks websites and programs that are not secure. A strictly configured firewall can sometimes impair the comfort of surfing, as many Internet pages are blocked. However, the firewall settings should only be loosened for pages that are absolutely trustworthy.
Operating system: Operating system vulnerabilities are a popular target for viruses and worms. Therefore, you should always use the latest version of the operating system you are using. Regular updates help fix vulnerabilities, making it more difficult for malicious programs to attack.
Access rights: Most modern operating systems allow you to create multiple user accounts with different access rights. Surfing from a user account with limited access rights can protect the most important system files. If you surf as a user with administrator rights, however, your entire system is at risk from an attack by a malicious program.
Backup copies: Save your files as a copy on external hard drives, DVD or CD-ROM. This ensures that no important files are lost in an attack.
E-mails: E-mail attachments that are unknown should never be opened. E-mails from unknown senders should also be handled with caution. If they do not appear 100% trustworthy, they should be deleted.
Protection For You And Your Data
Passwords: Do not store passwords on your PC. Click “No” if your browser asks if you want to save a password. Always enter passwords manually.
Personal information: Do not provide any personal information unless absolutely necessary and the website does not appear to be 100% trustworthy. Have a look at the terms and conditions and the imprint of websites to assess their seriousness.
Sweepstakes: Do not take part in opaque competitions. Sweepstakes according to the motto “You are the 1,000 visitor and have won a car” usually only serve to get out your e-mail address. This usually results in countless spam mails.
Anonymity: Stay anonymous on the Internet. If possible, use different e-mail addresses that do not contain your real name. Do not disclose any personal data or details about yourself to third parties. Particularly in chats and forums with contact with strangers caution is advised. With a person you only know from the Internet, you can never be sure that their information is true and what their intention is.
