There is a lot of information on the internet in regards to the rpcss.dll file and the malware that is getting attached to it. The general consensus is to do a full system restore after saving all the data you want to want to keep. If it were my computer I would try replacing the file with a clean one that is available on the internet for downloading. Copy and paste it into the system 32 folder.Choose the copy and replace option that comes up in a panel when you try to place it in the folder. This is a situation where periodic back-ups of all of your files need to be saved to an external hard-drive.I have been using large capacity flash drives the last several months.
Sorry Kevin; I hit the wrong reply button.
