Have you ever received an email several days after it was sent? Have you ever gotten an unwanted email with a fake “From” name, and wished you could find out where it came from? Read on to learn about some free tools that can help with both situations… |
There are times when it’s useful to trace the path that an email took to get to your inbox. The most common situation is suspected spam, when you want to discover the true source of an email.
Delays in receiving emails can also be diagnosed by tracing the path that emails take to you. But tracing emails on your own can be pretty frustrating.
Every email contains hidden information about the path it took to you, called “header information.” To most people, it looks like gibberish. Here is just a small part of a typical example:
With the possible exception of the “From” and “To” lines, ordinary mortals struggle to make sense out of email headers like this snippet. Geeks who run email servers or hunt down spammers may get eyestrain looking at raw headers, too. But there are many online tools that parse email headers to make them more legible by humans.
The Email Header Analyzer is a free online tool provided by MX Tools, Inc., a Texas-based firm that primarily serves network administrators and ISPs. Anyone can use the Analyzer, however; just paste a block of header information into the tool’s form and click the “Analyze Header” button.
The results include a bar graph, indicating any delays in the hops that the message took to reach you. It will also show you if any of the mail servers that relayed the message are on a spam blacklist. If the sender’s server is on a blacklist, that’s a big red flag that the message may be suspicious or malicious.
The Google Apps Toolbox also includes a message header analyzer. Its main purpose is to highlight delays in message relays and pinpoint their possible sources. (Typically, email messages are received within seconds, even if they must travel half-way around the globe.)
Google also provides brief, clear instructions on how to find message headers in Webmail messages, including Gmail, AOL, Yahoo! Mail, Excite Webmail, and Hotmail (now Outlook.com). Instructions for finding headers in desktop clients such as Microsoft Outlook, Apple Mail, Mozilla Thunderbird, and Opera are also given.
Sometimes, just hitting the “Reply” button on a message will paste the full header information as well as the message’s text into a message form. But this “show full headers in replies” option can look pretty messy, so it’s often disabled by default. You may have to find this option in your email app’s settings and enable it when necessary.
Interpeting Email Headers is another Google tutorial, for those who want to read raw email header info. It walks you through each line of a sample header, explaining in plain English what it means.
If a sender forges the “From” line, you may not be able to find the email address of the actual sender. But analyzing the email headers will show you at least that it WAS forged, and give you an indication where it originated.
For extra credit, you can paste the IP address found on the first “Received” line into the MaxMind GeoIP tool, to learn the approximate geographic location of the sender. (Note that first “Received” line is the one closest to the bottom of the headers. As messages travel over the Internet, the header lines stack up, so you need to read them in reverse order.)
For example, I got a classic 419 Scam message from a spammer today, showing this: “Received: from User (UnknownHost [197.211.53.1]) by vdt.com …” Sure enough, the MaxMind tool confirmed my suspicion that the sender was in Lagos, Nigeria.
If you think a message is from a spammer or a scammer, don’t reply to it. You’ll only be confirming to the bad guys that your address is valid, and possibly embroiling yourself in a heap of trouble. You can forward unwanted email(s) to the FTC at spam@uce.gov. Personally, I find it more satisfying to just hit the DELETE button and move on with my life.

Whether you’re on a Windows system or a Macintosh, there’s little more frustrating than the parade of apps that seem to start up every time you boot your computer. Worse, many of them are hidden behind-the-scenes, little “helper apps” that enable certain functions, listen for incoming queries, etc. For some, it’s almost impossible to figure out what they do and some of those might well be malware of some sort of another. It stinks!
Even benign programs like Skype, a very helpful video chat application, can exhibit the same sort of behaviors, starting up even if you don’t have an account and sitting on the Taskbar on your new Windows 10 system even if you never want to use the program. Any one program likely doesn’t have that much impact on your performance, but when you get 4, 5 or more starting up automatically, that’s going to have an impact on how your computer works.
Let’s just focus on your specific complaint, however. Skype automatically starting up on Microsoft Windows 10.

It just happened at our company, 2 of the PCs including mine. After much troubleshooting and reading online forums I found out the culprit to be Comodo Internet Security, specifically one of its component HIPS.
Here is the solution to this which I found out and personally applied on both my systems and Google Chrome is working now.
To solve the problem follow this steps:
1- Open the COMODO;2– Click on HIPS;3– In “HIPS Settings” the last option “Detect shellcode injection” click on “Exclusions”;4- Click the right mouse button and click on “ADD”> “Files” and goto “C: Program Files (x86) Google Chrome Application ” select “chrome.exe” and click on “Open”;5- Click on “OK”;6- Close COMODO and run Chrome.
