I had a working Malware Bytes subscription. I wanted to add a license for my wife's computer. The user interface for doing so is poorly written and not easily understandable. To make a long story short I tried to add a second license and ended up being charged for three new subscriptions for my machine and no extra license. There is no way to communicate with their customer service, so I am guessing that Malware Bytes does not have one. I was able to find a site where I could send them a message about this problem. I left three messages about one week apart and have not received a single reply. I ended up contacting my credit card company and had two of the three subscription charges reversed, The problem is I can no longer use the subscription I paid for because I do not have the initialization code to activate it. So here I am out about 85 bucks with no useable product. I will never recommend or give a positive review of Malware Bytes to anyone. Their lack of customer support is very suspicious and certainly raises a few legal red flags. Stay far far away from this company.
