I just noticed this problem about two days go with my Windows 7 HP laptop. I was online, and I went to a webpage on Google Chrome. Right when I clicked on it, all of the tabs I had opened went blank, and my computer automatically shut itself down. When I turned it back on, advertisment pop-ups kept appearing on the screen. I ran Malware Bytes and CC Cleaner. Malware Bytes removed two viruses, and a couple cookies. I thought the problem was solved, but I don't think it was.
After that, weird popups,(different ones than the popups that were appearing before,) kept appearing on my screen. I was not online at the time. They were appearing as adobe flash warnings, but I don't know if that's really what they are. I kept having to dismiss them. They would pop up every minute or so. Then when I tried to get on the internet, I realized everything was super slow. I've never had my laptop move this slowly before. It would take more than a minute for the internet to even come on, and then when you got to a webpage, it would take even longer to load. Pictures and videos weren't appearing as they normally would. Sometimes the pictures would show up, sometimes they wouldn't, and clicking a link, or picture freezes the computer for about ten seconds. And videos don't play normally on netflix, youtube, or anything. Sometimes you just hear the sound, or they will play, but the image doesn't move completely with the sound, and it stutters alot.
I opened up task manager, and it showed that CPU usage was at 100%, and Physical Memory was at 75%. I looked at the processes, and there were four internet explorers showing up, even though I was not using that browser. One of the internet explorers was taking up over 200,000 memory. I blocked internet explorer from popping up by itself, and I thought that would help. It didn't. It eventually showed four Explorers under processes, taking up the same amount of memory. Now today, it's showing that Google Chrome is taking up that much memory, and has more than one under processes. That can't be normal, right? I uploaded a picture of that, below. I ran all my anti-virus/malware programs again today, and they aren't finding anything. Another thing that is happening is that under task manager, a process called ctfmon.exe is constantly popping up. It's taking up alot of space, and more than one are under processes. Everytime I go to click it, to look at properties or file location, they all disappear. Ending the process tree works for about one minute, and then they all come back again.
I was trying to download the Farbar Recovery Scan Tool, but my computer isn't letting me. It's saying it's a virus. Any advice?
