I believe I have multiple viruses on my pc. As soon as my desktop loads the pop-ups begin, but there is no way for me to close them. I cannot access any other programs on my pc. I got into my control panel at one point, but could not uninstall the viruses because they were running. I have tons of documents and pictures I am desperate to back up before doing a system reset on my pc. But cannot access ANYTHING. PLEASE HELP.
