Trojan.Exploit.JS.O
by Marianna Schmudlach / October 13, 2008 6:02 AM PDT

SYMPTOMS:

The exploitation does not show any signs until the attacker infiltrates the system.

TECHNICAL DESCRIPTION:

The malware is a script written in Javascript. It is a part of known redirection and infection chains described in Trojan.Exploit.SSX (or later Trojan.Exploit.ANNZ ).


It is basically the same technique, but malware evolves and so a new features/exploits has been added:

CVE-2008-0647 which uses buffer overflow in the HanGamePluginCn18.HanGamePluginCn18.1 ActiveX control in HanGamePluginCn18.dll in Ourgame GLWorld 2.6.1.29.
A vulnerability for Adobe Flash player - CVE-2007-0071 which uses the d27cdb6e-ae6d-11cf-96b8-444553540000 CLSID.

Trojan.Autorun.ZG
by Marianna Schmudlach / October 13, 2008 6:03 AM PDT

SYMPTOMS:

The presence of a file named autorun.inf in the root of fixed/mobile drives (hard disks partitions, USB pen drives etc.) and the strange behavior of the computer.

TECHNICAL DESCRIPTION:

This files enables worms and other type of malware to be executed at startup. Be aware that the mere presence of this file isn?t to be considered a threat because it may be used by legitimate software that need to be run on access (like the autorun software of a CD). The file is used as an alternative/complementary to the autorun registry keys created by the malware.

Adware.FakeAntiVirus.M
by Marianna Schmudlach / October 13, 2008 6:04 AM PDT

SYMPTOMS:

This is a web-based piece of malware which tricks the user by making false assumptions about the security of their system.
While surfing, you might be directed from various sources ( spam, hidden redirections on shady webpages, malware already present on your computer ) to an allegedly online scanning tool used for malicious software detection.

Before the scan starts, it's noticeable the intent of giving the false impression that the user is infected from these pictures displayed on the webpage.

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?
