Hi and Welcome to LQ forums

the LQ Forum rules oblige the users to speak english ...

a hacker isn't going to necessarily hack your computer to steal files. They may want to hack it to use it as a slave in a botnet to launch attacks from. There is no folder i can think fo that you should give priority, you should secure your system overall by using good passwords, etc. But if you have any files that are for work or have sensitive data in them i'd encrypt those files. good luck.

Huh???--OP certainly looks like English to me. I suspect he/she is ESL, so lets give a break....

sorry OP, because my english no very power full.. but i tried my best...

by OP i believe he means original poster. So that would be you.

I think your English is excellent ... especially compared to any attempt I might make to speak in your native language.

Meanwhile ...

The single most important tool that you have in defending against "hackers" (and this is true in Linux or Windows, although it's not used enough there) is the concept of user-ids and privileges. You need to:

• Know which user-ids exist on your system, and why they are there. (Many systems come with more user-ids than you actually use, and some of those might be enabled for log-in.)
• Use the computer, on an ordinary daily basis, from a user-id that is not an Administrator.

In order for a hacker to "break in," he must cause a program to be run on your computer, from some account that has "super-user" privileges. The programs he wants to run are those that do nasty, system-wide things, but "ordinary" user-ids are not allowed to do such things. And that is what you want. The easiest way that a hacker has to introduce a rogue program into your machine is to trick you, or someone, into running it. But, if your account is non-privileged, the rogue program .. fails. And that is what you want.

Windows actually gets a bad reputation for just one reason: most people are running it from an Administrator account, with no passwords. They have never even been told about them, much less why they should use them. Consequently, the nasty folks slip a rogue-program to them, and the program executes without question... Anything that a privileged user (or any program executing with such privileges) tells the machine to do, no matter how nonsensical or destructive, will be done, without question, by the computer!
