What does a proxy warning mean?

Episode 1281 (1:50:48)

Reisel from California

Proxies are usually used by companies to see what you're doing. And if you're getting the popup, that means you may have been infected or compromised. Leo recommends Reisel back up his data. He could just turn proxy off, but he won't know if his system had been compromised, so it's best to format the hard drive, reinstall Windows, and then run updates.
