What is Subtitles.exe process?

Subtitles.exe is a malicious process created by coin miner virus

As I have pointed out previously, Subtitles.exe is a coin miner virus. The names of the executive file can be different, however, the impacts are generally the same. Since coin miners focus on cryptocurrency mining, they use all possible hardware power of your desktop to conduct this procedure. This malware does not care about the fact that you probably want to make use of your computer for other activities – it will constantly take over 80% of your processor power.

Subtitles.exe – Very high CPU and GPU use

Besides CPU usage, some of the coin miners additionally use GPU power for their tasks. In that situation, you will likely struggle also to see the mouse cursor moving – GPU is usually used on 100%. It is not as critical as processor for system work, so Subtitles.exe coin miner viruses don’t waste time on trifles and use it all. It sometimes may lead to bad results.

Shortly about cryptocurrency mining

Crypto mining is a term that means the operation of calculating the transaction block hash. That is a basic part of anything based on the blockchain technology. Since this operation takes a lot of calculations, a very strong computer is required. Exactly, the GPU is better for this purpose, because they have more cores available. Cryptomining farms are usually constructed of dozens of graphic cards to complete their task efficiently. Such systems are not usable for “usual” purposes, like gaming or browsing the Web. Fraudsters who gain money via this coin miner use someones’ PCs instead, even if they are used for the regular activity.

List of the typical coin miner symptoms

  • Extremely bad performance
  • CPU/GPU cooler fan creates a lot of noise
  • High temperature of the device (for laptops)
  • 80-90% consumption of CPU/GPU resources by an unknown process

  • How dangerous is the Subtitles.exe miner?

    Coin miners does not deal damage to your files. However, they make a lot of unpleasant things with the whole system

    First off, Subtitles.exe virus makes your computer overloaded. It is not able to run your applications anymore, since all processor power is used by a virus. That malware does not care for your wants, all it focuses on is generating profits on you. Even if you are patient, and you waited until web browser is open, you will likely struggle with extremely slow performance. Pages will open for years, any type of logins will take about a minute – just a horror story for a person that works online.

    “Visible” damage is not a single bad activity coin miners do to your computer. Subtitles.exe coin miner also deals damage to your OS. To perform all malevolent operations successfully, it ruins the security components of your system. You will likely see your Microsoft Defender disabled – malware stops it to prevent detection. If you check the HOSTS file, you will likely see a number of new entries – they are brought in by this coin miner to connect your PC to a malicious mining network. All these changes shall be thrown back to the initial state in the process of computer recovery.

    Hardware effects of coin miner activity

    Besides slowing down your PC, performing at peak level for long times may cause damage to your device as well as raise electricity bills. Hardware elements are created to easily get along with high load, but they can do so only when they are in a good shape.

    Little and well-protected CPU cooling system is hard to damage. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily cracked if touched while working, for example, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the extremely high load caused by Subtitles.exe malware can easily lead to graphic card failure2. GPUs are also tend to have very fast wearing when used for cryptocurrency mining. It is likely an undesirable case when your GPU’s performance decreases on 20-30% just after 1-2 weeks of being used in such a way.

    How did I get Subtitles.exe coin miner virus?

    Coin miners are spread through different ways, but their main sources are malicious banners and programs from dubious sources

    Coin miners are one of the most common malicious programs among “major” viruses. Adware often acts as a carrier for Subtitles.exe malware injection: it demonstrates you the banners, which include a link to malware downloading. Sure, this abstract “malware” may belong to any kind – another adware, spyware, rogue or backdoor. However, the statistics say that approximately 30% of all malware spread with the malicious banners are coin miners – and Subtitles.exe is right with them.

    The example of malicious banners you can see in the Internet

    Another way you could get this thing on your PC is by downloading it from the suspicious web page as a part of a program. People that spread hacked versions of popular programs (which do not require the license key) have small chances to make money. Hence, there is a huge temptation to include malware to the final package of the hacked application and acquire a coin for each installation. Before blaming these people for hacking and malware distribution, ask yourself – is it okay to avoid purchasing the program in this manner? It is more affordable to pay $20-$30 one time than to pay a much bigger figure for antivirus software as well as new parts for your desktop.

    How to remove the Subtitles.exe miner from my PC?

    The best way to get rid of this coin miner virus is to use anti-malware software

    Removing such a virus involves the use of special tool. Appropriate security tool should have high capability at scanning and be lightweight – in order to create no problems with usage even on weak PCs. Furthermore, it is recommended to have proactive security in your protection solution – to prevent the virus even before it starts. Microsoft Defender lacks these functions for different reasons. That’s why I’d suggest you to use a third-party anti-malware program for that goal. GridinSoft Anti-Malware is a perfect option that fits each of the mentioned qualities.3

    Prior to the malware removal, it is important to reboot your system into Safe Mode with Networking. Since Subtitles.exe miner consumes a lot of processor power, it is required to stop it before launching the security program. Otherwise, your scan will last for years, even though the GridinSoft program is pretty lightweight.

    Booting the PC into Safe Mode with Networking

    Press the Start button, then choose Power, and click on Reboot while holding the Shift key on the keyboard.

    Boot into Windows Safe Mode

    Windows will reboot into recovery mode. In that mode, choose Troubleshoot→ Startup Settings→ Safe Mode with Networking. Press the corresponding button on your keyboard to choose that option.

    When your system is in Safe Mode, all third-party apps, along with the majority of non-critical system components, are not launched with the system start. That allows you to clean the system without dealing with high processor usage of the coin miner.
