the last couple of days (2018-01-03), there has been a lot of
discussion about a pair of security vulnerabilities nicknamed Spectre and Meltdown. These affect all modern Intel processors, and (in the case of Spectre) many AMD processors and some ARM cores.
Spectre allows an attacker to bypass software checks to read data from
arbitrary locations in the current address space; Meltdown allows an
attacker to read arbitrary data from the operating system kernel’s
address space (which should normally be inaccessible to user programs).
The Raspberry Pi family is immune to this.

you run Windows (or Wine on Linux), do yourself a
favour and use PopTray (use for

For the most reliable (and supportable) version of PopTrayU go to this download page
and download v5.0.15.
This allows you to keep your
e-mail client closed and will also block unwanted spam (by installing
the example Rules.ini file given here):

REMINDER: I hope you followed the advice to install PopTray at the start of
this page and to NEVER keep your e-mail client open.
can I see
if my machine is sending out spam behind my back?
You can look at Internet activity on your PC. A simple visual proof is
to install NetMeter.
If you see attempts to send out data every few seconds then you might
have a problem.
However, don't be fooled, sometimes you'll see frames every 10s or so.
This can be Microsoft networking trying to reach another machine.
Likewise, you may see the effects of SSID broadcasts from a WiFi system.
To test further, you can download the rather complex

the details of what is going on. When you do this, make sure that your
browser, e-mail client and any other programs that talk to the internet
are not running. There may be background jobs such as Real, Apple,
Garmin and Google updates which you aren't aware of.
