Hey. I have been having significant issues with Windows. With the assistance from a couple of individuals very involved in the Forum and extremely knowledgeable, slowly some things are coming together. I just uninsalled Norton and was provided with a link to acquire MSE. So, now I have MSE, Anti-Malwarebytes and Defender. When MSE got completely on my laptop, I ran it and did the same with Anti-Malewarebytes, both of which came back with a clean bill of health although you would never know from my laptop's behavior. I then went to run Defender and the first text box that came up said that Defender was off and that if other security programs were running, to go to the Action Center to check their status. Also, if I wanted to turn it on to click on the link. I click on the click and another text box came up advising that Defender was not on and I could restart my computer to make it start or I could manually start it. That language was followed by an error warning giving a series of numbers, which of course I didn't write down. I restarted the laptop and again, I got one of those boxes. This time I went to where Defender lives to see if I could start it that way. No luck. I clicked on the Defender icon and nothing happened. One of the text boxes (not the error one) had opened at some point This time when I clicked on the start link, the little wheel next to the cursor which is usually indicative that a program/application was in the process of starting just turned and turned, and Defender did not open. When I again clicked on the Defender icon, nothing happened. I restarted the laptop and I'm pretty sure it was the Defender icon that I clicked and was advised the program was already running which was followed by one the boxes saying it wasn't on. I don't know if its on, if it's off, or if it's vacationing. I do know that it will not open. It's like it's just a shell, but I saw it had all its parts (I think) when I visited it's home. I'm sure it's pretty evident, but I have absolutely no idea what's happening and needless to say, what to do. Therefore, I'm eliciting your expert computer programming knowledge.and Windows 7 expertise to see if you can assist me in my endeavors at fixing yet another of my problems. Thanks a whole bunch.
