How does this happen? do ip addresses change daily according to internet service provider? does running torrents sharing make it easy? can an email containing a trogen hack in and do wats mentioned above?

Answer 1

Theoretically speaking, yes, if someone has your IP, they can try to gain unauthorized access.  The key word here is "try."  It is a very, very tedious, long, and frustrating process to gain control over a PC, especially if the target PC is not a server and/or is up to date and doesn't have any obvious holes.  The chances of a someone attacking your PC directly and getting in is very small and mostly negligible.

When someone gains control over a PC, it usually happens at the fault of the user, who may be incompetent, or has done something to leave open a hole for the attacker to exploit.

All in all, if you are behind a router and/or a firewall, it is pretty much impossible for an attacker to gain access to your PC over the Internet.

Almost all IP addresses change once in a while, these are dynamic IPs.  How often they change depends on the ISP, but most definitely not every day.  Running torrents will make you discoverable, but that's it.  An e-mail can contain a trojan or virus and run on your PC, but only if you open it or execute the attachment.

Hope this helps.
