Thread: Can someone enter through the router to PC

Hello,because anyone can enter through my router to my PC, does it, without first performing a trojan was installed? I have no fritzbox or so, it is a normal adsl router.

If you install an accessible external service (eg a web server) on your network that contains a security hole, which eg allows you to apply this process, then a firewall or a router is not much use. In general, however, it is not possible (yet there is no absolute certainty, unless you pull the plug).
