I received the following message today informing me that Host Process for Windows Tasks was modified. http://s13.postimage.org/4pq4n2tbb/taskhost.jpg It just came up out of the blue. I was not browsing anywhere, I hadn't downloaded anything, I hadn't run any files. My last scans have all been clean. As you can see the "deny" option is unavailable. How do I find out what's going on? I can't scan taskhost.exe because ESET says it can't open the file. Edit: The deny option became available - so obviously I chose that.
