First off I am not tech geeks please don't respond if you expect me to be able to understand "jargon". I have an old computer so I don't expect super fast performance. However after I installed NIS my computer is so slow as to be essentially useless. Did not have this problem with my AVast free virus protection Switched to NIS for supposedly better product. Wish I had kept AVast. I have run a power erase it found no infections. What can I do. ALL processes are SLOOOOW. Inherent/all applications. Everything
