Today. For no reason. I installed nothing at all. I saw some executable-box flash for like a second. Well, I am not sure, if it was an executable or not, it happened too fast. It was like a small window. It appeared for a moment and disappeared. I wondered what it was. Anyway. Soon after I had like 20 or more instances of dllhost.exe *32 in my task manager. They were taking up my CPU usage and memory. After I kill the process they come back up again.
