I can vouch for Ken and his course. I work full time in IT, and I was fortunate enough to have my company pay for the course as a CPE. I can tell you that it was well worth my time to sit under Ken's knowledge and expertise. He has been at this longer than most on this forum, and his knowledge of the Windows operating system is pretty deep. While I, too, felt fairly confident in my malware removal skills as well as the tools available at that point, what I learned from Ken was a specific diagnostic and troubleshooting process to go through which would help me to be more effective and efficient than just running x tool, then y tool, then z tool & hoping that I got it all.
Also, having completed the course I now have a resource in Ken when I come up against something totally new & emerging (e.g. Cryptolocker or Poweliks). There's a good chance that he's already heard about it and is working on a process for removal.
Some of you are balking at the price, and I can understand that. As small business owners, we often don't want to spend money, especially on training, unless we have to. The price is not unreasonable at all in the corporate realm, especially when you consider the expenses involved in flying to a city, renting a venue & hoping to have enough people show up to make it profitable.
I mean, why should I pay a technician $100-$200 to remove a virus from my computer when I can just go on bleepingcomputer.com, print out a removal guide a do it myself? That's just waaay to much money being charged to fix my computer, right? Our customers pay for our expertise in order to get the job done right. Though I have knowledge, skill and experience, I am willing to pay to learn from someone who has more knowledge skill and experience than I do. Malware is not going away, and indications are that it will become more pervasive and more insidious. Investing money in my skill set will, in the long run, make me more profitable at what I do. That's why I think that the class is worth the money and the time.
