Dale,
I have noted those emails as well,, and sadly, all of them I have recieved have originated from emails of people in the Hobby,, so there is a tie in somewhere with this site, or SSW,, Not sure how, or why, but that is what it appears from my end,,
SSW, like this site, is hosted off of a Linux based server system. So, its not being distributed through the sites, either SSW or SH.
Some of these worms get into a user's system, reads their address book, and then replicates and sends copies of the worm to those email addresses. These in turn get to other systems, read their address books, and the cycle continues. The primary targets are Windows operating system based machines use Microsoft Internet Explorer. And, it stands to reason that CL enthusiasts email other CL enthusiasts, so if one gets infected, it spreads, among other places, throughout the CL enthusiast email world.
Antivirus/malware software is always playing catch-up with the hackers/malicious code developers out there. So, if one of these bugs make their way to your system prior to the antivirus/malware software being updated, you are hosed.
The best defense is not to open emails from those you don't know, keep your antivirus/antimalware and operating system software updated, and run a complete scan at least once a week. For killing malware, I continually find Malwarebytes' product to be the most effective, although its not perfect and others prefer different products.
For the more adventurous who have a little time on their hands and don't want the expense of buying a Mac (which also runs on a Unix based OS), there are various distributions that allow you a good graphical user interface and web browsers such as Firefox, Google Chrome, etc. These can be loaded onto a Windows based system (if you have room on your hard drive, and most do). Systems are set up to dual boot, e.g. at boot up, you can decide whether you want to run Windows or your Unix based distribution. For web surfing I normally opt for using the Linux based system, as it is less susceptable to being target and affected as Windows based systems running MS Internet Explorer
