Hi

The Electronic Frontier Foundation has an interesting page open which gives very good and easy to understand information: "Tips, Tools and How-tos For Safer Online Communications". You can choose between many different topics you may are interested in.

Hi

Not sure how far this is true as this comes from oversea, but those who try to break into Tor are surely absolute pros. But not all who use Tor are pros and have in mind to do some thing illegally. They just want privacy. Difficult decision in todays world.

Hi

A little warning for users of Window 8 versions:

If you run Avast 2015, have as OS any version of Windows 8 and up and install the newest update from Windows (KB3000850) https://support.microsoft.com/kb/3000850 , which is over 700 MB, you will face problems in different ways. Even your system may take the update at first, you will face later problems like system crash or OS can not shut down or OS even no more starts up.

Avast has not solved the problem now. So a need is any way to set a restore point if you still think that you want to try the mentioned update, in case you run any Windows 8 version. (I run the Enterprise version and also had to deinstall the mentioned update by using the restore tool)

Here a link from Avast: https://forum.avast.com/index.php?topic=160717.0

Take care and surf safe / Dan :)
 
Hi

Avast has in the mean time updated his software with the needed patch. If you want to go further into the subject, read in the given link above from the Avast forum which explains what kind of update was done.

(Today I first removed the Avast Software from my Windows 8.1 Enterprise, booted the system twice, then installed the Windows update, booted the system twice and then installed the newest Avast software and booted the OS twice. Every thing works fine and my system restore point is also set again with the new update).

Next topic: The new NotCompatible

This topic will be interesting if you run an android mobile device. The Trojan is highly dangerous and very clever made. Here we go:
