I enabled SD a while ago and checked my email etc... I then downloaded a music video from Youtube and uploaded it to another social networking site. I decided to run a scan with malwarebytes. It had been a while. So it wanted to install the latest version. I installed it but then it wanted to restart. I told it to restart later. Then I got an error message. So I went ahead and restarted. SD was enabled. I am certain of that. I just thought that I could update MB with SD enabled and then update it again later when it was disabled. I use to do that kind of thing with Returnil all the time. Anyway, when my computer was trying to restart I got an error message When my computer finally restarted, the new shortcut for malwarebytes was there and so was the video that I had downloaded. The only thing that I have done differently is that I have recently added Appguard. I am wondering if Appguard has caused this? It is causing some other problems. My OS is Vista 64 bit. I just wonder if anything like this has ever happened to anyone else. I am wondering if I should uninstall Appguard or if I should go back to using Returnil 2010. I am so disappointed.
