Have I been hijacked if my computer asks me for my password more than once?

by on June 29, 2009

Q: Have I been hijacked if when I switch users I type in my password and the computer acts like it is going to boot up and then it asks me for my password again?

    First things first, do a scan of your PC for any nasty software. Here is a free on-line scanning tool I suggest: http://www.kaspersky.com/virusscanner

    If you want to make sure the logon prompt you’re getting is legit, the best thing to do is enable the ‘Alt-Ctrl-Del’ login screen in Windows.

    To do this in Vista follow these instructions: http://www.howtogeek.com/howto/windows-vista/enable-ctrlaltdelete-for-vista-logon-screen/

    To do this in Windows XP follow these instructions: http://support.microsoft.com/kb/291559

    Once this is setup, you will need to hold down ALT & CTRL keys and then press DEL. This will bring up a legit login screen you can be assured if safe.

    Just to clarify Mark’s answer… The online Kaspersky virus scanner will detect whether your computer has been infected with malware, a virus, etc. However, it will NOT remove infections from your computer. For that, you will need a program such as Kaspersky Internet Security 2009 (includes firewall and other tools), Kaspersky Antivirus 2009, or Avast http://www.avast.com/eng/programs.html (free for home users). I recommend that you do not use products such as Norton or AVG.

    I use Kaspersky Internet Security 2009 on my Microsoft Windows computers. One nice thing about KIS 2009 is that, in addition to detecting infections, it also detects holes in your computer’s security and provides webpage addresses where you can learn how to eliminate each of the vulnerabilities. I do not know if either Kaspersky Antivirus 2009 and/or the online Kaspersky virus scanner can detect vulnerabilities.

    PS: The firewall security in Microsoft Windows is rather bad. If you decide to not purchase KIS 2009, you may wish to use the free (for home users) ZoneAlarm Firewall from http://www.zonealarm.com/security/en-us/zonealarm-pc-security-free-firewall.htm instead.

    Does this help?
