ZA caught and quarantined this trojan downloader recently. Subsequent scans (ZA, Malawarebytes, HitMan Pro) indicated all was OK. However, today when I attempted to logout, my password did not work, and I received the message "Other people are logged on..." when I was the only one logged on. (After I rebooted, my PW was OK.) Should I be concerned?
Probably just some temporary glitch on the side of the OS. Follow all the steps as detailed below inclusing getting your logs analysed at bleepingcomputer or spywarehammer.
