Hi I hope someone can help me. I continue getting a low disc warning. In the past I could run MS Security Essentials and it would locate the virus and remove it. I have tried running it but it doesn't find anything. I have tried looking in the folder where they used to be found, and couldn't find anything. I clear disc space, and delete files and still get the warning and 0 bytes on C:. When I unplug the internet, I dont get the warning and the disc space is normal. I have deleted about 2GB of files so far and dont want to delete more if not necessary. I can't access the internet because the pages wont fully load. I have to continue going to Task Manager and end process on several dllhost.exe*32 that are running. I dont know what to do. Any thoughts. Help is greatly appreciated. My machine is about 4 years old and is Windows Vista64 I have also tried running malwarebytes and it finds nothing.
