I use my personal PC for work, and was called today by the Security dept who informed me that my Windows 8 PC is hosting porn, and people are trying to access it from the Internet. They said my computer must have been hacked, and that I need to take it off the network a.s.a.p. They said it's also possible that personal information on the PC is being hacked. Because it's not a work computer, they would not provide any help or information, only that I should have it looked at, and not to plug it back into the work network. I use it on my home network as well. I have Norton 360 and it updates and runs live update and scans daily and has never reported any problems. I just downloaded and ran "Norton Power Erase" and it doesn't detect any issues either. All is supposedly okay. I am really worried, since I have no idea what I am looking for, and if any of my files are infected, so even if I backed it all up, wiped and reformatted the drives, and reinstalled the OS and all the programs, that once I restored my backup files, I could just be reinfecting the PC. Any suggestions? I am desperate.
I have noticed lately that my computer is very slow, and that websites often time out before I get to them. Not sure if this is related or not.
