User account changed configuration and pwds "forgotten" by the system

So, I’ve been running smoothly for most of the time but last time I booted my Lap a login screen appears. I had this disabled as I’m the only one using that machine. After trying several times it appears none of my passwords works. I log in as root (offline mode) to reset the pwd and then log in again with my standard user. Fine again and I disable log in so no account is asked when booting. As I got a new access point I had to reconfigure wireless connection. Shortly after I do so (1hr approx), the Wireless gets disconnected and it request my WEP key again. I entered and verified several times but no connection. I confirm with another device that the wireless is working and the WEP key is correct. So I restart to see if this fixes my connection and ,surprise, log in screen again and no pwd is recognized

I haven’t touch that machine again but I’m afraid a malicious SW can be stealing my pwd. Only SW I have installed is from the official repositories

Recommendations? tips?

Thanks in advance!

If there is another forum more related to security please let me know because I posted here just for the login part

Odd have you run fsck to see if you have a corrupted file system. Note should be run from a CD since it does not work on mounted partitions

Try in text mode. Ctrl-alt-f1.

You mean to log in text mode?

Yes.

If you can, the password is correct.

Thanks, I did it and no, the PWD is not recognized. What can be “forgetting” my pwds and why the root account has not been affected?

I’m going to create a new account and delete the original one to see if there is any change
