What is Sedsvc.exe process?

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

As I have specified in the introduction, Sedsvc.exe is a coin miner virus. The names of the .exe file may be different, but the impacts are almost always the same. Considering that coin miners aim at cryptocurrency mining, they utilize all available hardware power of your desktop to conduct this process. This malware does not pay attention to the fact that you may want to make use of your system for other activities – it will constantly use over 80% of your processor power.

Sedsvc.exe – Really high CPU as well as GPU use

Besides CPU utilization, some of the coin miners also make use of GPU power for their tasks. In that instance, you will struggle also to see the mouse cursor moving – GPU is often used on 100%. It is not as important as processor for system work, so Sedsvc.exe coin miner viruses do not waste time on trifles and utilize it all. It sometimes can cause bad effects.

Shortly about cryptocurrency mining

Crypto mining term means the activity of calculating the transaction block hash. That is a basic element of anything based on the blockchain technology. Since this operation takes a lot of calculations, a high-end desktop is needed. Exactly, the graphic card is better for this purpose, because they have more cores available. Cryptocurrency mining farms are usually constructed of tens and hundreds of video cards to complete their task efficiently. Such computer systems are not usable for “general” purposes, like gaming or web browsing. Crooks who make profit via this coin miner use someones’ hardware instead, even if they are used for the regular activity.2

List of the typical coin miner symptoms

    “Visible” harm is not a solitary unpleasant thing coin miners perform to your computer. Sedsvc.exe coin miner additionally deals damage to your OS. To complete all malevolent operations correctly, it wrecks the protection mechanisms of your system. You will likely see your Microsoft Defender disabled – malware halts it to prevent recognition. If you check the HOSTS file, you will likely see a number of new entries – they are brought in by this trojan miner to connect your computer to a malicious mining network. All these adjustments shall be reverted to the original in the process of PC recovery.

    Hardware effects of coin miner activity

    Besides slowing down your PC, performing at peak level for a long period of time can cause damage to your device and increase electricity bills. Hardware elements are created to easily deal with high load, but they are good with it only in case when they are in a good shape.

    Small and well-protected processor fan is hard to broke. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily broke if touched while running, for instance, by the user much earlier before the malware injection. Malfunctioning cooling system, together with the extremely high load caused by Sedsvc.exe virus can easily lead to GPU failure3. Graphic cards are also prone to have increased wearing when utilized for crypto mining. It is surely an undesirable case when your GPU’s performance plunges 20-30% just after several weeks of being exploited in such a way.

    How did I get Sedsvc.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 the most common malicious programs through “severe” malware. Adware sometimes serves as a carrier for Sedsvc.exe malware infiltration: it demonstrates you the banners, which contain a link to malware downloading. Yes, this abstract “malware” may belong to any type – yet another adware, spyware, rogue or backdoor. However, the statistics say that around 30% of all viruses spread through the malevolent banners are coin miners – and Sedsvc.exe is right with them.4

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    Another way you could get this thing on your computer is by downloading it from the unreliable web page as a part of a program. Users who spread hacked versions of well-known programs (which do not demand 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 app and acquire a coin for every installation. Prior to criticizing these people for hacking and also malware distribution, ask yourself – is it okay to avoid paying for the program in such a way? It is more affordable to pay $20-$30 at once than to pay a much bigger sum for antivirus software and new parts for your computer.

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

In addition, it is better to have on-run protection in your security tool – to halt the virus even before it starts. Microsoft Defender lacks these elements for different factors. That’s why I’d recommend you to use a third-party anti-malware program for that purpose. GridinSoft Anti-Malware is a perfect choice that fits all of the mentioned characteristics.5
