My Internet speed before installing is 200. After installing is 50. After UNINSTALLING is still 50. You have to manually un-do the changes made to your computer that Hamachi made. Here is the solution: https://community.logmein.com/t5/LogMeIn-Hamachi-Discussions/Installing-Hamachi-slows-my-internet-speed/m-p/217907#M18346 This solution works for me. Internet went back to 200 after doing this. I REALLY wish that LogMeIn support would chime in officially regarding this. I have not contacted them myself, but someone else in that thread did, and they reported that support would not acknowledge it.
