Also we could always boot up a Live Linux Mint DVD/USB and ignore what is on that PC.
My normal computer is on the fritz temporarily. Am using borrowed computer that a relative got used from Device Pitstop. A Compaq Presario. I can get on the Internet but certain websites are mysteriously only partially available or not available at all. On Craigslist I can see and respond to ads but can't post or access my own CL account. I get a message saying the webpage can't be displayed. Other websites I either get a message saying it can't find the webpage, or clicking the link for it just gives me a blank page.
I have checked the Control Panel thoroughly and can't find any reference to these pages having been blocked by the previous owner. Does anyone know of anything I can do to resolve these issues?
