This question already has an answer here:

The answer suggested in the 'duplicate' is about a different issue. But since my original wording of the question seems to have not been clear - here's a second attempt:

Is there any danger of any of my computer's files being read or changed (mainly - infected by malware) in the following scenario:

  • I have file sharing turned off (in "advanced sharing settings").
  • I connect to a public wireless network (such as at a restaurant), and surf the web.

Assuming: No vulnerabilities are exploited on the web browser (or its plugins etc.).

This is a question about dangers of connecting to the router itself. Can someone on the same network access my computer?

This is not about anyone sniffing my passwords or what websites I'm visiting. Let's assume I just Google "StackExchange" and then disconnect. Is that safe?

So, the router is your endpoint, not some website on the internet? –  Marcel Jul 22 '13 at 11:24

When you connect to a public network, you don't know who else is connected.

The problems in this kind of network aren't only the attackers, but also malwares and viruses, as you said.

For example, many users aren't able to figure out if their computer is infected, and they connect in public networks with the result of infect them inadvertently.

The only way to avoid these dangers, IMHO, is to install a good "Internet Security", with a complete protection from viruses, malwares, trojans, spam, hackers, etc.

PS: I'm sorry for my bad English
