What is Trojan.ZeroAccess?

Trojan.ZeroAccess is a malicious Trojan horse, which was named like that because of the string found in its kernel driver code that points to the ZeroAccess folder. However, you can also find it named as max++. Note that there are many versions of this trojan, like Trojan.Zeroaccess!kmem, Trojan.Zeroaccess.B, Trojan.zeroaccess!inf, Trojan.Zeroaccess!inf2, Trojan.Zeroaccess!inf3, Trojan.Zeroaccess.C, Trojan.Zeroaccess!inf4 or the latest Trojan.Zeroaccess!gen10 and Trojan.Zeroaccess!gen11. Each of them can easily hide deep inside your PC system without any sign because they are closely related to ZeroAccess rootkit  that was developed for this task. However, this is not what it was created for. The main thing what this trojan is used for is to open the backdoors of the compromised PC and download malware or similar malicious software to it. It can also create a hidden system file which helps it to store all of its components. As long as this threat is considered an advanced trojan horse, it has also been noticed that it is capable of updating itself through the peer-to-peer network. This is a very helpful capability that allows for its authors to improve Trojan.Zeroaccess virus as frequently as possible. They can easily fill it with more functions and set it for new tasks.

How can Trojan.ZeroAccess infect my computer?

There are several ways how you can get infected with Trojan.ZeroAccess or one of its modified versions. It may come to your computer after clicking on malicious link or after visiting a website, which is infected with Trojan.Zeroaccess virus. Please, stay away from suspicious sites  that can either be visited with the help of browser hijackers or voluntarily. As soon as this dangerous trojan horse gets inside the target PC, Trojan.ZeroAccess downloads an application that starts monitoring victim's web searches and browsing habits. It can also try to redirect your search results for trying to make the money through pay-per-click advertising scheme and similar methods. Besides, Trojan.ZeroAccess is also capable to download other threats, like rogue applications or malware. These scams work on displaying for the user invented information about threats found and then push them to purchase licensed version. Opening a back door of the system and connecting it to a command and control (C&C) server is also a simple task for this trojan. This allows for the attacker to get the access to the compromised computer and perform various unwanted actions on the PC.

Comments on Trojan.Zeroaccess

If this virus is so dangerous and I want to try this product but asking for my CC how can I process the purchase? I am afraid my information be collected!
Used Spyhunter in the attempt of removing the Trojan.Zeroaccess. Spyhunter indicated the virus was isolated and deleted, however, upon running a second scan with McAfee, the virus remained/ Stored under C:WINDOWSassemblyGAC_32Desktop.ini. I still cant get rid of it. I try to access the file in Safe Mode in attempt to delete it....It prompts me that access is denied. I am lost. I need help.
My wifes PC had ZeroAccess. If her PC was on and connected to the network, all other PCs (family of five) on the network ground to a halt re. internet traffic. The first clue it was a virus and not a network component issue, was the fact that the MS Security Essentials (Win XP SP3) service had been halted inexplicably on my wifes PC, and the service would not restart. It was impossible to update Malwarebytes or to get MS Security Essentials running.

I booted from an Ultimate Boot CD for Windows (UCB4WIN) which I created years ago to remove a virus I had encountered a few years ago. I used Registry Restore to bring back the registry from a few days prior to the infection. (I have lost faith entirely in Windows System Restore, I dont even bother trying to use it anymore.) I then rebooted into Windows, and could update Malwarebytes. A full scan revealed "Trojan.0Access". Malwarebytes removed most of it, but suspicious folders remained in C:Recycler. RogueKiller was able to delete everything. I took the time to run CCleaner as well, cleaning over 5 GB of junk of the PC. Also updated MS Security Essentials.
