Linkoptimizer is a trojan – in fact it is an army of trojans, consisting mainly of droppers and downloaders with two ultimate purposes: But so far Linkoptimizer is the first to combine these techniques and add its own flavour to them by developing new ones.Īlthough there is a lot to be said about this complex threat, this article will focus on the big picture of the trojan and the new elements it brings to the scene, especially its methods of evasion, how they work and how its authors have adapted them. There are other ways to make code 'stealthy', some of which have already been discussed in various articles. This means that such techniques can be applied only to a limited number of targets, and updates are required even for slight changes in the environment. Recently we have seen what a significant impact advanced rootkits can have on the AV industry, but in order to achieve a really good rootkit one has to go deeper into the system, making obscure undocumented changes, therefore introducing a greater risk of system instability. O23 - Service: ewido security suite control - ewido networks - C:\Ewido\security suite\ has pushed the limits of persistence and stealth to a point where it manages to evade AV detection most of the time.

Here is my Hijack this log, thx in advance. Whenever I clean it with Adaware it comes back. My Adaware keeps finding a registry thing called LinkOptimizer, and it is causing popups and seems to be greatly slowing my connection speed.
