Thanks kelderek I managed to figure that when I read the pop up carefully, Peter I did have Norton antivirus installed but all it did was tell me I was infected and that it was unable to repair it, I could not quarentine a couple of them so I deleted them and of course it messed up my computer being in the system 32 folder; finally I reformatted my system, installed a firewall with its antivirus and had not have any problems except weekly warnings that someone has been trying to access my ports. The only glitch is that I have not been able to do a complete scan because Norton freezes, I have done it through folders. One more thing if you back up your computer you still need to install all your Poser products( Victoria, Michael etc) from the original cd or download or you could use the back up like the ones Roxio does. I have on my D drive a copy of my previous Runtime folder.
