Browsing Security
- Keep an eye open for fake URL's (phishing sites). Some letters look very similar (e.g. 0/O/o, l/1/I, etc. In particular, the extensions .ch and .cn look very similar)
- Don't click on advertisements. Even very reputable websites (like the homepage of a newspaper or tv-channel) can contain fake advertisements which try to harm your computer if you click on it.
- In particular: don't click on advertisements which tell you that your computer "might be infected/in danger" or similar. These advertisements are mostly infectious itself.
- If your browser warns you that a security certificate doesn't match, be cautious.
