How to remove rootkits and malware?

[Daniel22]

I have downloaded and ran the programme Rootkit Hunter and the results are worrying.

I don't know much about malware other than a malicious individual has persistently been installing it onto my machines via malicious emails - this time targeting my iPhone 4 (which I promptly got rid of upon discovering this individual's presence and replaced with a new Samsung S4, which is probably infected as well now) first; and from there using my house Wifi network to get onto my Macbook Pro 10.8.3 (which is the machine I am on now, and the machine the results refer to); and also my Samsung Galaxy Tab 10.1; and most likely the phones and computers belonging to other members of my family are compromised as well.

The following are the worrying results identified by Rootkit Hunter:

For "Checking LD_LIBRARY_PATH variable", it says in yellow "skipped".

For "Checking for hidden processes", it also says in yellow "skipped".

I also have red warning notices in relation to system configuration file checks and filesystem checks alerting me to the following:

"Checking if SSH protocol v1 in allowed The SSH configuration option 'Protocol' has not been set";

"Checking if syslog remote logging is allowed Syslog configuration file allows remote logging: install.* .0.1:32376"

"Checking /dev for suspicious file types Suspicious file types found in /dev: /dev/fd/6: MS Windows icon resource"

"Checking for hidden files and directories Hidden file found: /usr/share/man/man5/. rhosts.5: troff or preprocessor input text".

I do not know how to interpret these results other than of course realising they are alerting me to the fact that something is wrong and needs fixing.

I do not know exactly what Rootkit Hunter is telling me is wrong, and I do not know how to fix the problems it has identified.

I would greatly appreciate it if anybody could perhaps tell me how I can do these things. And any advice on which programmes to use for my Samsung machines and the best way to protect my devices in the future would also be greatly appreciated.

RKill is a program that was developed at BleepingComputer.com that attempts to terminate known malware processes
so that your normal security software can then run and clean your computer of infections.
When RKill runs it will kill malware processes and then removes incorrect executable associations and fixes policies
that stop us from using certain tools. When finished it will display a log file that shows the processes that were
terminated while the program was running.

As RKill only terminates a program's running process, and does not delete any files, after running it you should not reboot
your computer as any malware processes that are configured to start automatically will just be started again.
Instead, after running RKill you should immediately scan your computer using the requested scans I've included.

Please download Rkill by Grinler from one of the links below and save it to your desktop.

Link 1

Link 2

• On Windows XP double-click on the Rkill desktop icon to run the tool.
• On Windows Vista/Windows 7 or 8, right-click on the Rkill desktop icon and select Run As Administrator
• A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
• If not, delete the file, then download and use the one provided in Link 2.
• If it does not work, repeat the process and attempt to use one of the remaining links until the tool runs.
• If the tool does not run from any of the links provided, please let me know.
• Do not reboot the computer, you will need to run the application again.
  

STEP 01
Backup the Registry:
Modifying the Registry can create unforeseen problems, so it always wise to create a backup before doing so.

• Choose a location for the backup.
  
  • Note: the default location is C:\Windows\ERDNT which is acceptable.
    

  [*]Make sure that at least the first two check boxes are selected. [*]Click on OK [*]Then click on YES to create the folder. [*]Note: if it is necessary to restore the registry, open the backup folder and start ERDNT.exe
