Remove Acwzmain.accde Trojan Virus (July 2019 Update)

Acwzmain.accde is a legit Microsoft Office file, but sometimes trojans can infect it.

Acwzmain.accde is linked to the recent malware threat called O97m/mamacse.f . The path C:\Program Files (x86)\Microsoft Office\root\Office16\ACCWIZ\ACWZMAIN.ACCDE has been detected as part of the Trojan horse O97m/mamacse.f.

The types of harm that a virus of the Trojan Horse family could do to your computer are many and in a lot of cases, the users don’t even know what part of their system is being targeted by an ongoing Trojan Horse infection. What’s even worse is that most Trojan Horse victims tend to be unaware of the infection in their machines due to the sneaky nature of the Trojans. Considering all those, as well as many other aspects of this malicious group of programs, it is essential that every PC and Mac (that’s right, even Macs aren’t immune to Trojan Horse infections!) has some basic understanding of how those malicious programs operate, how they can enter a given computer, what damage they may cause in it and, most importantly, how one could manage to eliminate such a virus before the task of the Trojan gets completed.

Acwzmain.accde has been infected by the O97m/Mamacse.f Trojan Horse

There is one particular Trojan Horse virus that we will be focusing on in this post. Its name is  O97m/Mamacse.f and it is one of the newer Trojans – it was recently reported as many users have had their computers attacked by it in the last couple of days. One problem with this threat is that there needs to be done more research on it so that everything is known about its capabilities. This is why we cannot tell you with hundred percent certainty what its goal may be if it gets to you. Many of the Trojan Horse representatives (Idle Buddy“Drive by exploit”) have varied abilities and, because of that, could be used in multiple ways.

In some cases, the infection may be tasked with taking over your computer in some way. This is usually done in order to make the attacked machine part of the massive network of infected computers that the Trojan controls. Such networks are known as botnets, as the machines in them are remotely controlled by the hackers behind the Trojan and are collectively used for tasks such as mining BitCoin, conducting large-scale online attacks (DDoS) or distributing other types of malware such as Ransomware and Spyware via massive spam message campaigns. In such cases, there could be various symptoms of the infection like high CPU and RAM use, system unresponsiveness, software failure with many random errors, unauthorized deletion or modification of different files, folders and registry keys as well as many more.

In other instances, however, there may be no visible symptoms at all. This is mostly when Trojans like O97m/Mamacse.f are used as espionage tools. In those cases, the malware program may be able to collect sensitive data like banking details, online passwords and usernames, different important personal or business-related files, conversations and more. In those situations, the malware would be optimized for stealth and would probably not show any signs of its presence.
