Risk is based on many factors, which include:

Threat
Vulnerability
Criticality

If I read your post correctly, it sounds like you feel like there is a threat based on your interaction with some groups on the net and your systems are vulnerable. So, the main question which remains is how critical is the Linux computer system you are worried about?

If the system is really important and a breach would amount to serious loss, then you should really consider getting a professional to help you.

If the system has nothing important running on it; then you could just rebuild it from a scratch if you are worried.

If the system has backups, you could recover the system from a backup that was from a time prior to the hacking incident being discovered.

There are lots of options and the way you move forward depending on the risk profile of the system and that depends on the intersection of the three areas I mentioned above (1) threat, (2) vulnerability and (3) criticality.

fstab

FSTAB(5)							File Formats Manual							  FSTAB(5)

NAME

       fstab, mtab - list of file systems to mount, mounted file system table.

SYNOPSIS

       /etc/fstab

       /etc/mtab

DESCRIPTION

       /etc/fstab  is  a table of file system to mount at boot time, /etc/mtab is a table of currently mounted file systems as maintained by mount
       and umount.

       /etc/fstab is not read by mount as it should be.  It is instead a simple shell script listing the three devices that Minix needs  to  oper-
       ate:   The device names of the root file system, the temporary (scratch) file system, and the file system for /usr.  Of these only the /usr
       file system is mounted in /etc/rc, the scratch file system is there for the system administrator to test new kernels,  or  as  a  temporary
       file system.

       /etc/mtab contains lines of four fields.  The layout is:

	      device	directory    type    options

       These fields may be explained as follows:

       device
	      A block special device.

       directory
	      Mount point.

       type
	      Either 1, or 2, indicating a V1 or V2 file system.

       options
	      Either ro, or rw, indicating a read-only or read-write mounted file system.

FILES

       /etc/fstab     Shell script naming three important file systems.

       /etc/mtab      List of mounted file systems.

SEE ALSO

       printroot(8), mount(1), fsck(1), mkfs(1).

BUGS

       /etc/fstab is a joke.
