removal by Lucia Danes - - | Type: Trojans

Kryptik Trojan is a dangerous malware that can steal your sensitive data and severely damage your computer

Kryptik Trojan

Win32:Kryptik is a trojan that typically enters users machines via infected installers and then tries to acquire administration rights. By doing so, Kryptik virus can make the needed modifications to registry entries and other settings, which lets it execute each time Windows is booted. The infection is very persistent and hard to detect, as Kryptik trojan deletes its executable file after infiltration.

SUMMARY

Distribution Malicious installers from spam emails, infected sites, etc.

Kryptik Trojan is capable of many malicious acts, such as:

  • Legitimate programs can crash, work slow and become nonresponsive;
  • The workstation might crash or restart on its own;
  • The CPU power might be excessive while trojan is executing its malicious activities;
  • Certain files might get deleted (.sol);
  • The trojan can enable hackers to take full control of the PC;
  • Kryptik can steal sensitive data and transfer it to cybercriminals via encrypted communication (RC4[1] encryption algorithm).

It might be challenging to notice this trojan. Thus, that is another reason to install reputable security software such as Reimage or Plumbytes Anti-MalwareNorton Internet Security. These anti-malware programs can detect and remove Kryptik Trojan in Safe Mode with Networking.

Kryptik virus can also modify your browser settings – proxy[2] ones in particular. As a result, you are forced to encounter ads on every website you visit. They can be in the form of pop-ups, deals, banners, hyperlinks, work as redirects, etc. This activity can lead you to malicious websites, where more malware can be implanted into your PC without your knowledge.

Win32:Kryptik also continually attempts to download malicious files from the internet, slowing down your connection speed and the browser. Thus, if your computer and internet speed suddenly started to struggle – it might be the first warning sign.

The virus gathers and sends out the following information:

  • Digital certificates and their passwords;
  • Users name and computer name;
  • Login usernames and passwords for certain programs and services;
  • Email address information, including Outlook;
  • Operating system version, etc.

As evident, this information can help cyber criminals to obtain extremely sensitive data, like bank account information or other credentials. It goes without saying that such information should be kept private, as it can lead to stolen money or even identity theft.

As we already mentioned, an antivirus program can take care of Kryptik removal. Do not attempt to remove the virus manually as it can lead to permanent damage to your system files. Instead, follow our instructions below this article.

Trojans can enter machines in many different ways

The most prevalent distribution method of trojans is via malicious installers. They can come from websites that are injected with malicious code, hacked sites, repacked/illegal software or its keygens, codecs, fake updates, social media links and malicious attachments in spam emails.

Thus, to protect yourself from such cyber threats, users should be more careful while browsing world wide web. We suggest avoiding any third-party websites that have file-sharing feature, never using peer-to-peer clients, downloading only original software, deleting spam emails instead of opening their attachments and securing the PC with powerful anti-malware software.

Kryptik Trojan should be eliminated as soon as possible

Trojans are one of the most dangerous and widely spread malware types. After all, it can lead to total destruction of not only software but hardware too. Thus, it is vital to eliminate the threat before more severe damage is caused.

Security experts from virusler.info.tr[3] advise not to undertake manual Kryptik Trojan removal. This process can only be executed by IT professionals and is too complicated for regular users.

To remove Kryptik virus safely, download Reimage or Plumbytes Anti-MalwareNorton Internet Security, bring it up to date and perform a full system scan. Do not forget that malicious program might block proper operation of security software. Thus, you should reboot your PC in Safe Mode with Networking, as explained below.
