I have been a long-time supporter of ESET. On a Windows platform, their software has a small footprint, is beautifully designed, stable, stays out of the way, and does a great job. I have long since those days touted ESET for being a great company with a great product.
I purchased Multi Device Security which comes with Cyber Security Pro for my Macbook Pro (Yosemite) and I have been nothing but DISGUTED with ESET as a whole with this product. Not only has ESET known of this bug for 9 MONTHS, but they have yet to bring a fix to market. The year license I have with my software was wasted because I simply do not tolerate software that deteriorates the performance of my machine. With CSP, it was often found running my CPU at 90-95% for hours on end and it has this infuriating shutdown hangup. Where my MBP used to shut down in 3-5 seconds, it was now well over 60 seconds. Who knows if it's causing damage to the underlying OS or not, but this has put a SERIOUS dent in whether I'm going to stick with them for another year, seeing as they just wasted the time never getting a fix out.
I'm a software developer; I know fixes don't come in a matter of days. But this is inexcusable and ESET should honestly be ashamed of themselves. I've since taken CSP off my Macbook and will look for other alternatives that don't jeopardize the stability of operations on my machine. Get your act together ESET. 9 MONTHS.
