What is Acwzmain.accde ?

Acwzmain.accde virus

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

 

Acwzmain.accde is a legitimate Microsoft Windows file that can be found in C:\Program Files (x86)\Microsoft Office\root\Office16\ACCWIZ\ACWZMAIN.ACCDE. Sometimes, trojans find their way to infect such files and stay hidden under the antivirus programs radar. One such example is when Acwzmain.accde is linked to the recent malware threat called O97m/Mamacse.f

Recently, our “How to remove” team has received numerous reports of people claiming that their computer has been infected by some sort of a “virus” which goes by the name of Acwzmain.accde. Some of the users have reported that they have started to experience some unusual system activity such as sudden crashes, sluggishness and unusual software errors. However, in some cases, this infection may have no symptoms at all. This is because Acwzmain.accde is not a regular virus but a nasty Trojan Horse infection which can sneak in the PC silently and run multiple malicious activities in the background. As most threats of its category, this piece of malware is designed to stay in the system for as long as possible and to secretly launch harmful processes and tasks that serve the needs of the criminal hackers who stand behind the infection. Before you know it, Acwzmain.accde may have managed to collect information about your passwords and login credentials, and may have handed it over to the crooks or it may have made some modifications to your system’s registry and software. But this is not the worst a virus like this may be capable of – Trojans like this one can create security holes by blocking the protection of your security program and inviting other nasty infections such as Ransomware or Spyware in the system without your knowledge. They may also corrupt your data, delete and replace files or format the hard drives in no time. That’s why, if you have the slightest doubt that you might have been infected with a threat of this kind, it is best to read this article to the end and check your system for its hidden presence.

But, how do you know if your PC has really been compromised by a Trojan like O97m/Mamacse.f or “Drive-by exploit”  and how to remove the malware program once and for all? Well, there are some common symptoms that you should keep an eye out for in order to catch such threats before they damage your machine in an irreversible way. For instance, it is a good idea to observe the system’s performance and notice if it starts to experience sudden productivity drops and sluggishness. If your computer is struggling to run programs that have previously run smoothly, or if the system is running a lot of background stuff that you do not know the origin of or do not remember having installed, this could be a sign of some unauthorized background activity. Another possible symptom could be that your antivirus or system-maintenance programs may not work or may not be able to complete a system scan properly. This is because one of the first things that many Trojans do when sneaking in a computer is they block the processes of programs that can help identify and remove them. So if you find that programs like your antivirus, your online security tools or your scanner apps are not working properly, then this should be seen as a major red flag that something may be wrong with the computer. Sadly, some advanced Trojan-based infections, including the O97m/Mamacse.f Trojan, may have no symptoms at all until they complete their criminal agenda, which makes them extremely harmful and difficult to detect and remove.

So, what to do?

Well, before you go to the extreme measure of reinstalling your OS, there are a few steps that may help you catch and remove the Trojan virus without need for anything drastic. If you don’t know where to start, take a look at the removal guide below and use its instructions to get an idea on how to effectively deal with your problem.
