Security Shenanigans – May 2010

I’ve noticed a few irritating trends in the virus/spam/spyware world recently.  Here are some things to watch out for:

Web Nasties
  • Steer clear of downloading screensavers, they can often be infected with viruses
  • Steer clear of apparently free tools that contain irritating adware, e.g. freeripmp3 which contains “Adware.ADON”
  • Be very careful of Online Poker sites.  These often require the downloading of software or a browser add-on which could be infected.
  • If you are browsing the web and are informed that your computer has a virus or infection treat this message with a healthy degree of scepticism.  Has the message popped up from your security software?  This should be fairly obvious.
    • Here, for example is what a security pop-up from ESET Smart Security looks like:

    • E.g. here is what a security pop-up from Norton Internet Security looks like:

    • It’s very common for spyware to infiltrate your PC by pretending to be legitimate software which tells you that you have a security problem on your PC which can magically be fixed by downloading a product such as AntiVirus 2010.  When this software is unwittingly downloaded it can really get medieval on your computer!  Here are some examples:

    • So, look at the title of the warning pop-up message.  Is it coming from your security software?  You do have security software (AKA anti-virus) yes?  Is the message popping up as window in your web browser?  If so then shut down all web browser windows.  Can’t close them all?  Try using the Alt+F4 keyboard combination.  Failing that, save any changes to any documents you might have open elsewhere and restart your computer.
Email Nasties

As always, be really careful with email attachments.  It’s amazing how often we can forget this.  Do you know the sender?  If not I’m inclined to just delete the email if it has the attachment.  If you know the sender then ask yourself if this is expected.  If not, email them and ask them if they meant to send you an attachment.  If they say yes, even then it pays to be cautious…
