Since this operation takes a lot of calculations, a strong PC is required. Exactly, the video card is better for this purpose, because they have more cores available. Cryptocurrency mining farms are usually constructed of tens and hundreds of GPUs to complete their task efficiently. Such computer systems are not usable for “usual” purposes, like gaming or web browsing. Fraudsters who make profit via this coin miner use someones’ hardware instead, even if they are used for the regular activity.

“Visible” harm is not a solitary negative thing coin miners do to your system. Updaterstartuputility.exe coin miner additionally deals damage to your operating system.

All these adjustments shall be reverted to the original in the process of computer recovery.

Hardware effects of coin miner activity

Besides making your PC slow, performing at peak level for long times may trigger damage to your device and increase electricity expenses. Hardware elements are created to easily deal with high load, but they are good with it only when they are in a good shape.

Tiny and well-protected processor cooling system is quite hard to crack. Meanwhile, graphic cards have large and easy-to-access fans, which can be easily cracked if touched while spinning, for example, by the user much before the coin-miner injection. Malfunctioning cooling system, together with the unusually high load caused by Updaterstartuputility.exe can easily lead to graphic processing unit failure1. Video cards are also tend to have fast wearing when utilized for cryptocurrency mining. It is surely a bad case when the performance of your graphic card decreases on 20-30% only after 1-2 weeks of being used in such a way.

How did I get Updaterstartuputility.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 widespread malevolent programs through “serious” malware. Adware often serves as a carrier for Updaterstartuputility.exe malware injection: it demonstrates you the banners, which have a link to malware downloading. Yes, this abstract “malware” may belong to any type – another adware, spyware, rogue or backdoor. However, the statistics say that approximately 30% of all malware spread through the malicious banners are coin miners – and Updaterstartuputility.exe is right with them.

Unwanted banners adware

The example of malicious banners you can see in the Internet

An additional way you could get this thing on your PC is by downloading it from the dubious website as a part of a program. Users that spread hacked variants of well-known programs (which do not need the license key) have small chances to get paid. Therefore, there is a very big temptation to add malware to the final package of the hacked app and get a coin for each installation. Prior to blaming these guys for hacking and also malware distribution, ask yourself – is it OK to avoid buying the program in such a way? It is much cheaper to pay $20-$30 at once than to pay a much greater figure for antivirus program as well as new parts for your computer.

How to remove the Updaterstartuputility.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 demands the use of specific software. Effective security tool must have high performance at scanning and be lightweight – in order to create no problems with utilization also on weak systems. On top of that, it is better to have on-run security in your security tool – to halt the virus even before it launches. Microsoft Defender lacks these elements for different reasons. That’s why I’d recommend you to use a third-party anti-malware program for that objective. GridinSoft Anti-Malware is a superb choice that fits each of the discussed qualities.2

Prior to the virus removal, it is important to reboot your system into Safe Mode with Networking. Since Updaterstartuputility.exe miner consumes a lot of CPU power, it is needed to stop it before launching the security program.
