It is also known as the Microsoft Sync Center, which allows users to sync files and folders with network servers, mobile devices, and other computers.

Mobsync.exe is designed to run in the background and automatically synchronize files when changes are detected, making it easier for users to keep their files up-to-date and accessible from multiple devices.

Mobsync.exe – Very high CPU/GPU usage

Besides CPU utilization, some of the coin miners also use GPU power for their operations. In that situation, you will likely struggle even to see the mouse arrow moving – GPU is usually used on 100%. It is not as critical as processor for system work, so Mobsync.exe coin miner viruses do not waste time on trifles and utilize all of it. It sometimes can cause unhappy effects.

Shortly about cryptocurrency mining

Crypto mining means the action of calculating the transaction block hash. That is a basic element of any project based on the blockchain technology. Since this operation takes a lot of calculations, a very powerful desktop is required. Exactly, the video card is better for this task, because they have more cores available. Cryptomining farms usually consist of tens and hundreds of video cards to conduct their activity effectively. Such computer systems are not usable for “general” purposes, like gaming or web browsing. Crooks who make profit via this coin miner use someones’ computers instead, even if they are used for the regular activity.¹

How dangerous is the Mobsync.exe miner?

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

Firstly, Mobsync.exe virus makes your system overloaded. It is unable to run your applications now, as all processor power is used by a virus. That malware does not care for your demands, all it focuses on is making money on you. Even if you are patient, and you waited until web browser is open, you will likely experience exceptionally sluggish performance. Pages will open up for years, any sort of logins will take about a minute – just a headache for a person that works online.

Mobsync.exe Technical Summary.

“Visible” damage is not a solitary bad activity coin miners do to your PC. Mobsync.exe coin miner also deals damage to your OS. To carry out all malevolent functions correctly, it wrecks the protection features of your system. You will likely see your Microsoft Defender disabled – malware halts it to avoid 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 cryptomining network. All these adjustments are about to be gone back to the initial state in the process of system recovery.

Hardware effects of coin miner activity

Besides decreasing your PC’s performance, running at peak power for long times may cause damage to your device as well as raise electricity bills. PC components are created to easily deal with high load, but they are good with it only when they are in a good shape.

Small and well-protected CPU fan is quite hard to crack. Meanwhile, GPUs have large and easy-to-access rotors, which can be easily broke if affected while spinning, for instance, by the user much before the malware injection. Malfunctioning cooling system, together with the very high load caused by Mobsync.exe can easily lead to GPU failure². GPUs are also tend to have very fast wearing when used for cryptocurrency mining. It is likely an undesirable situation when the performance of your GPU decreases on 20-30% only after 1-2 weeks of being used in such a way.

How did I get Mobsync.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 “serious” malware. Adware sometimes acts as a carrier for Mobsync.exe malware injection: it demonstrates you the banners, which include a link to malware downloading. Sure, this abstract “malware” can belong to any kind – an additional adware, spyware, rogue or backdoor. However, the statistics show that about 30% of all malware spread with the malicious banners are coin miners – and Mobsync.exe is just among 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 dubious site as a part of a program. People that spread hacked variants of favored programs (which do not need the license key) have small chances to get paid. For this reason, there is a very big temptation to include malware to the final package of the hacked application and get a coin for each setup. Before blaming these guys for hacking and malware distribution, ask yourself – is it alright to avoid purchasing the program in this manner? It is more affordable to pay $20-$30 at once than to pay a much greater figure for antivirus software as well as new parts for your PC.

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

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

Eliminating such a virus demands the use of special app. Effective antivirus must have high capability at scanning and be lightweight – in order to create no problems with utilization also on weak PCs. Additionally, it is better to have on-run security in your security tool – to stop 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 reason. GridinSoft Anti-Malware is an ideal option that fits all of the discussed qualities.³

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

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

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 computer is in Safe Mode, all third-party programs, just like the majority of non-crucial system components, are not started with the system start. That gives you the ability to clean the computer without dealing with high CPU usage of the coin miner.
