chkrootkit and rkhunter installed. Thank-you, Steve Stern. nmap installed. Thank-you, Rahul. automatic updating is on. The old system (10 years old) was probably infected early summer 2011. Whether the spyware came from a bad web site via Firefox, or e-mail via yahoo e-mail (thru Firefox), or some other way, I don't know. As far as I know, no files that I've knowingly created have been changed or lost. But there's a definite uncanny correlation between e-mail that I write and spams and spoofs that I receive, both in timing and in content (judging by subject lines). There is almost certainly at least some sort of keystroke logger on this dinosaur. One of the main reasons for getting the new system is to solve this problem. (I was long overdue for an upgrade too.) Though the probability of infection is very small, I know from first hand experience it's not zero. Better diligence and less laziness on my part can reduce that probability some, but I still would like something to detect and remove whatever slips through the cracks, and because I'm human. I do not currently plan to connect to the new home system from the outside. But I may someday connect to work computers, clouds, etc. from home via ssh, vpn, etc. I will not be running a mail server, or any other kind of server, on my new system. thanks, Bill. --- On Thu, 3/21/13, William Mattison <wcmattison@xxxxxxxxx> wrote: > From: William Mattison <wcmattison@xxxxxxxxx> > Subject: Fedora 18 security questions. > To: users@xxxxxxxxxxxxxxxxxxxxxxx > Date: Thursday, March 21, 2013, 10:31 AM > I have a single desktop connected > only to the internet.
