From the Trendlabs Security Intelligence Blog:
Who says you can't teach old malware new tricks? Recently, we reported on how ZBOT had made a comeback of sorts in 2013; this was followed by media reports that it was now spreading via Facebook. Now, we have spotted a new ZBOT variant that can spread on its own.
This particular ZBOT variant arrives through a malicious PDF file disguised as a sales invoice document. If the user opens this file using Adobe Reader, it triggers an exploit which causes the following pop-up window to appear: [Screenshot]
While this is going on, the malicious ZBOT variant - WORM_ZBOT.GJ - is dropped onto the system and run. It is here that several differences start to appear.
First of all, WORM_ZBOT.GJ has an autoupdate routine: it can download and run an updated copy of itself. Secondly, however, it can spread onto other systems via removable drives, like USB thumb drives.

Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
