CryptInject

CryptInject is a new stealthy virus of the Trojan Horse type that can evade most antivirus programs and infect computers without symptoms. CryptInject takes over the attacked machine by misleading the user and then secretly initiates different malicious processes without getting noticed.

The CryptInject trojan can damage computer programs and applications

The malware programs of the Trojan Horse family are generally known for being very stealthy and difficult to detect on time. This is even more true about new threats such a CryptInject. What makes such recently released Trojan Horse viruses especially tricky to spot and intercept on time has to do with the inability of most antivirus solutions to reliably detect newer Trojan Horses. The reason for this stems from the method used to detect incoming threats by the majority of antiviruses out there. In most cases, an antivirus program would use its extensive database to recognize software that is deemed unsafe. This detection method is very effective but only against viruses that have already been listed in the database. However, its weakness is that newer threats such as CryptInject that aren’t yet added to the database are able to remain practically invisible to the antivirus. Of course, some more advanced security programs offer additional detection features to detect new threats based on behavioral patterns but, for the most part, if a given threat isn’t in the database of the antivirus, it won’t get noticed by the security program and would be free to infect the attacked computer.

The CryptInject Trojan

If your antivirus cannot effectively detect the CryptInject trojan, your only other chance of spotting the infection on time is if you notice any of its typical symptoms. Unfortunately, many Trojans don’t typically trigger any red flags that could give them away. Despite this, there are certain things you should be on the lookout for as they may indeed indicate that your computer has been attacked by a Trojan.

One of these potential symptoms is the infamous Blue Screen of Death crash. This is an error screen following a system crash that is triggered by a serious issue with the computer. Though there could be many different causes for a Blue Screen crash, a Trojan Horse infection is certainly one of them, especially if this symptom is combined with overall computer sluggishness, screen freezes, or settings changes in the system or the browser that you have not approved or made yourself.

Generally, any type of system disturbances could be a potential sign of a Trojan Horse virus so be sure to always investigate anything that seems to be out of order with your PC.

The damage CryptInject could cause

Because of their versatility, Trojans like this one are used in different cybercrime campaigns and can complete a variety of harmful actions, including spying on the user’s activities, acquiring sensitive personal and/or professional information, inserting new threats in the attacked machine, and even taking over the whole OS and starting new processes without the user’s knowledge or direct approval. All of this means that the damage that a Trojan may cause could be very unpredictable, especially if we are talking about a new threat such as CryptInject. That being said, regardless of what the end-goal of the virus is, you still must make sure to remove the threat ASAP and, hopefully, you will be able to do so after checking out the removal guide we’ve added to this article.

Some of the steps will likely require you to exit the page. Bookmark it for later reference.

Reboot in Safe Mode (use this guide if you don’t know how to do it).

Step2

WARNING! READ CAREFULLY BEFORE PROCEEDING!

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab. Try to determine which processes are dangerous.

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 

Step3

Hold together the Start Key and R. Type appwiz.cpl –> OK.

You are now in the Control Panel. Look for suspicious entries. Uninstall it/them. If you see a screen like this when you click Uninstall, choose NO:

Step4

To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
a professional malware removal tool.

Type msconfig in the search field and hit enter. A window will pop-up:

msconfig_opt

Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.

  • Remember this step – if you have reason to believe a bigger threat (like ransomware) is on your PC, check everything here.

Hold the Start Key and R –  copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

hosts_opt (1)

If there are suspicious IPs below “Localhost” – write to us in the comments.

Step5

Type Regedit in the windows search field and press Enter.

Once inside, press CTRL and F together and type the virus’s Name. Right click and delete any entries you find with a similar name. If they don’t show up this way, go manually to these directories and delete/uninstall them:

  • HKEY_CURRENT_USER—-Software—–Random Directory. It could be any one of them – ask us if you can’t discern which ones are malicious.
    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

If the guide doesn’t help, download the anti-virus program we recommended or try our free online virus scanner. Also, you can always ask us in the comments for help!
