You're not alone, its probably a computer techs biggest weakness. Trouble with computer techs today is they know only one good way of cleaning a computer? format the computer back to default settings. There argument is..."its safer doing it this way" but the real truth is, they don't know how to remove malware correctly, apart from running malwarebytes and then they remove the software they used to clean malware from the machine and charge the customer a fee.
They don't want the customer to know about free software like malwarebytes adwcleaner etc etc, because they know that customer will be back infected with malware again real soon. That is a sign of a bad tech. Inform your customer with good information on how to protect themselves against malware. Help them setup there machine and show them how to stay safe.
I like you Ankh Warrior the way your trying to broaden your knowledge, that's a sign of a good tech. Now back to the question you asked before I get started on a rant about the modern day tech
Farbar is not that difficult to use. Just got to learn to read log files and spot malware. Everyone has there own way of removing malware, there is no wrong or right way. as long as the machine is clean at the end, that's all that matters. Farbar can speed up this process. But remember it don't always work or help removal all malware. Its a tool to use in conjunction other tools.
At this time, I wish our forum was receiving more malware removal questions so you can help and learn. But at this moment in time, the forum is a bit slow. Like GS said. you may need to join a forum that teach you the skills. But remember this can take a while and you would be expected to put time and effort in on the forum. helping with malware removal.
In the near future I will be releasing videos on another site on the whole process and all the tools you need. Been meaning on doing this for a while, it won't be free..but it will be well worth it.
