Use two-step authentication to secure your Gmail from hackers

do not get infected by malware

How many times this year have you received an email from someone you know asking you to “click here?”  I usually receive one or two a week.  In almost every case it is from someone who has experienced an email hack or theft of their contact list.

In many cases, the thief has captured the unsuspecting person’s user id and password, and has logged on as that person.  If you send them an email asking, “did you really send this?”, you get a vague reply saying, “yes it is me.”

Like you, I consider myself an informed net-izen.  I don’t “click here.”  I follow a pretty common-sense list of rules to help keep my computer safe.  But, who knows?  It can happen to even the most careful of us if you believe articles in the trade press.

For this reason, I just employed two-step authentication on my Gmail account.  Several of my online banking accounts already enforce it, so why not.

It’s really not much less convenient than using a user id and password to sign in.  You have to authenticate each browser on each device on which you use your Gmail account.  You use a one-time pass-code sent to you by text on your cell phone for each authentication.  After that, it is business as usual.

If you want to sign on from a computer somewhere that doesn’t have cell-phone service, Google has an app for that — Google Authenticator.

In this way, even if the thief has your user id and password, they cannot sign in to your account without your cell phone.

Feel free to call me or send me a note if you want more information.

How to avoid Malware

do not get infected by malware

If your PC has not been infected by Malware, it is almost certain that you know someone who has had this horribly frustrating experience.

I have disinfected a lot of clients’ PCs. As a result, I have some thoughts on their experiences you might find useful:

  • This may sound elementary, but buy a good anti-virus/anti-malware product.  The ones you get free usually won’t protect you from much.  Some may even cause your PC to become infected.
  • As if to contradict the first paragraph, if your ISP (Internet Service Provider) provides an anti-virus/anti-malware product as a benefit of subscribing, use it.  Comcast provides “Norton Security Suite”  for up to 7 computers included in residential Internet subscriptions.
  • Be sure to keep your operating system up-to-date.  Microsoft supplies frequent security updates for all of its actively supported products.  Keep your updates up to date.
  • Keep your anti-virus/anti-malware software up to date.  Many paid licenses have to be renewed periodically.  If you let your anti-virus/anti-malware license expire, you are not adequately protected.
  • Only download software from the owner’s site.  If you do a Google search on “Adobe Reader”  you will find many listings.  The top listings on this search are not the official Adobe web site.  In fact, you don’t see “” until the fourth listing.  The others will send you an adulterated copy of Adobe reader.  Many will contain an unexpected payload of something as simple as a tool bar, or as malicious as the “Conduit” virus.  Always download from the vendor’s own site.
  • If your PC starts displaying unexpected pop-ups, or your browser’s address bar doesn’t take you to the site you’re expecting, stop clicking on things.  You will only worsen the infection.  The pop-ups will usually warn you of an infection and ask you to click on a link.  At the link, you will find what looks to be the solution to your problem, so you download it.  This usually magnifies the infection.  Your only practical solution is to buy a new computer or have your current computer repaired.  If you buy a new one, you will probably repeat the behavior that caused the infection in the first place.  If you get it repaired, you will probably get a bunch of additional services:  disinfection of your PC, installation of all Microsoft security updates, optimization of your PC to improve performance and a brief tutorial on how to avoid the problem in the future.
  • If this is the first piece of software you’re installing from a vendor, read their license agreement … really.  If you don’t like the agreement, don’t use the product.
  • Have at least two user ids on your PC.  One user id should be for the administrator and should have a secure password.  The other(s) should be for standard users.  The difference is that the standard users cannot install software.  When they want to install something new on a shared PC, they will have to get the administrator’s okay (and password).  When a malicious web site tries to sneak something in, it will likely be prevented by the administrator.

I hope you find these suggestions useful and that they contribute to your infection-free computing.
