I'm having trouble with a Windows 7 PC. There are multiple instances of dllhost.exe running, 19 as of now. They all come from Windows/System32, and a few of them are hogging a lot of memory. The description on all of them is COM Surrogate. I'm not really sure where to go from here, as I would rather not reinstall Windows. If I try to kill one of the processes, another will pop up. I haven't ruled out malware as being the problem, even though I have ran many scanners including MBAM. and rootkit scanners. These processes are literally taking up over 50% of my system memory.
Randomly, the system (upon boot sometimes) will tell me that COM Surrogate has failed, or something to that nature. Another, apparently random thing that pops up is a small Internet Explorer window that asks me if I'm sure I'd like to leave this page. Even if I'm not browsing. Both of these can pop up immediately after boot, but not routinely.
