When my email stopped working today I called the provider who said they were having difficulties with their server & were "manually pushing thru emails" .... He said they had about 1/2 Million emails backed up & didn't know when they would get things going. A couple minutes later he called back & said, actually, the problem with my account is that they had disabled it because someone had been sending spam using my name. I asked him how that could be & he said someone might have a way to get my administrative password for email. He then told me I should install an antivirus/malware program. I told him I believed I didn't need one because I have a Mac. He said all computers should have them & that I should change my passwords on sensitive accounts just to be sure whoever was using my email didn't have access to my other passwords. He said there could be keyloggers (sp?) that are able to view what I am typing. Is this so? If I don't have an antivirus installed presently, how am I able to check anything? What action would you suggest I take? I'm a relatively inexperienced user who visits few websites and sends/receives few emails. Am I in jeopardy?
