How to remove Parallax from your computer

Also Known As: Parallax remote access trojan
Type: Trojan
Damage level: Severe

What kind of malware is Parallax?

Parallax is a remote administration tool (RAT), which can be purchased on a hacker forum. Remote administration tools are programs used by cyber criminals to take full control over the targeted computer. Generally, they use RATs to infect systems with malware, steal personal information and perform other actions that enable them to generate revenue in various ways.

Parallax RAT in detail

Parallax can be used to control multiple infected computers at once. Research shows that this RAT can be used to download and execute various files on victims' computers, steal credentials (logins and passwords) saved on Mozilla Firefox, Google Chrome, Thunderbird, Outlook, view screen activity, manage files, run various commands and record keystrokes.

Therefore, cyber criminals can infect operating systems that have Parallax installed with other malware. They often use RATs to infect systems with Trojans, ransomware-type software and other malicious programs. This software can cause serious problems such as loss of files, money, identity theft, issues relating to privacy, browsing safety, and so on.

They can also use Parallax to install cryptocurrency miners that can use computer resources to solve mathematical problems. Programs of this type cause high CPU (and other hardware) usage, which results in higher electricity bills. They can also cause hardware to overheat and system crashes that can lead to data loss.

Cyber criminals behind Parallax can run/execute various commands on the infected computer. They could shut down, restart the computer, disable running/enabled antivirus programs or other security suites, create scheduled tasks, and perform various other actions.

Another Parallax feature is keystroke logging - it can be used to record keyboard input (keys pressed) and steal sensitive information such as banking details, credentials (logins, passwords) of various accounts, and so on. Typically, cyber criminals misuse stolen information to steal identities, make fraudulent purchases, transactions, etc.

The same can be done by misusing credentials saved on Mozilla Firefox, Google Chrome, Thunderbird, and Outlook, which the cyber criminals behind Parallax can also steal.

Additionally, Parallax includes a file management feature, which can be used to delete, modify and manage files in other ways. Parallax's screen monitoring feature allows cyber criminals to monitor screen activity, and thus they can monitor everything users' actions on the infected computer.

More about RATs

Other examples of RATs are ShadowTechRAT, Bandook and JhoneRAT. There are legitimate and unofficial RATs, which can be used by cyber criminals who seek to control computers remotely and infect them with malware, steal personal information, install cryptocurrency miners, and so on.

In any case, cyber criminals attempt to trick people into installing RATs so that they can perform actions to generate revenue. If you believe that Parallax or another RAT is installed on the operating system (and it was not installed intentionally), remove it immediately.

How did Parallax infiltrate my computer?

In most cases, cyber criminals attempt to trick people into installing RATs and various malicious programs through spam campaigns, Trojans, dubious software download channels, fake software updaters and unofficial software activation ('cracking') tools.

Cyber criminals often send emails that contain attachments such as malicious MS Office documents, Java Script files, PDF documents, executable files (.exe), and archive files such as ZIP, RAR. They seek to trick recipients into opening a malicious file that, if opened, installs rogue software.

They include website links that also download malicious files. Third party software downloaders, free file hosting websites, Peer-to-Peer networks (torrent clients, eMule), websites host free software and other similar sources are used by cyber criminals to host malicious files.

Typically, the files are disguised as harmless and legitimate, however, if downloaded and opened, they cause installation of malicious programs. Trojans cause chain infections and proliferate malware. In summary, if a computer is infected with a Trojan, it will be infected with other malware as well.

Operating systems can be infected through fake software updaters, which install malware or infect systems by exploiting bugs/flaws of outdated software. Tools that supposedly bypass activation of licensed (paid) software are often designed to install malicious software. People who use them risk infecting systems with high-risk malware or RATs such as Parallax.

How to avoid installation of malware

Do not trust or open attachments or web links that are included in irrelevant emails. Typically, these emails are sent from unknown, suspicious addresses and disguised as important and official. All software and files should be downloaded from official websites and via direct links.

It is not safe to use other sources. Examples of dubious software download tools/channels are provided above. Installed software should be updated using tools and functions designed by official developers. If installed programs are not free and require activation, this should be done properly.

Avoid 'cracking' tools, since they cause installation of malware and are illegal. Keep systems/computers safe by regularly scanning them with a reputable antivirus or anti-spyware suite. If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Click 'Options' at the top and uncheck 'Hide Empty Locations' and 'Hide Windows Entries' options

manual malware removal step 5Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

locate the malware file you want to remove

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

searching for malware file on your computer

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs.

These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.

To be sure your computer is free of malware infections, we recommend scanning it with Combo Cleaner Antivirus for Windows.
