OfficeClickToRun.exe — Is it Safe or Virus?

Written by Robert Bailey
OfficeClickToRun.exe is an executable file that is part of the Microsoft Office Click-to-Run process. It is associated with the Microsoft Office Click-to-Run (SxS) software developed by Microsoft. This executable file plays a crucial role in the functioning of the Click-to-Run process, which is used to install and update Microsoft Office applications on a computer.

Most often, this process stays low in the Task Manager, consuming minimal RAM and CPU power. However, seeing it taking over 80% of your CPU means that it is not a genuine OfficeClickToRun process. Malware, particularly coin miner trojans, often hijack the names of system processes in order to disguise themselves. Though, they cannot disguise an obscenely high resource consumption. This indicator is determinative when it comes to understanding the nature of that process.

Shortly about cryptocurrency mining

Cryptomining farms are usually constructed of tens and hundreds of graphic cards to conduct their activity effectively.

Fraudsters who gain money via this coin miner use someones’ computers instead, even if they are used for the regular activity.

    Hardware effects of coin miner activity

    Besides making your PC slow, running at peak level for long times may cause damage to your device and raise electricity costs. Hardware elements are designed to easily deal with high load, but they are good with it only in case when they are in a good shape.

    Little and well-protected processor fan is hard to broke.

Malfunctioning cooling system, together with the very high load caused by Officeclicktorun.exe malware can easily lead to graphic card failure1. GPUs are also tend to have increased wearing when used for crypto mining. It is likely an unwanted case when your GPU’s performance decreases on 20-30% just after several weeks of being used in such a way.

    How did I get Officeclicktorun.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 among “major” malware. Adware frequently serves as a carrier for Officeclicktorun.exe malware infiltration: it shows you the banners, which have a link to malware downloading. Yes, this abstract “malware” may belong to any type – yet another adware, spyware, rogue or backdoor. But the statistics show that approximately 30% of all malware spread with the malevolent banners are coin miners – and Officeclicktorun.exe is just with them.2

    Unwanted banners adware

    The example of malicious banners you can see in the Internet

    One more way you could get this thing on your computer is by downloading it from the untrustworthy website as a part of a program. Users who spread hacked variants of well-known programs (which do not need the license key) have small chances to earn money. For this reason, there is a huge temptation to add in malware to the final package of the hacked app and acquire a coin for each setup. Prior to blaming these people for hacking and also malware distribution, ask yourself – is it OK to avoid purchasing the program in such a way? It is more affordable to pay $20-$30 at once than to pay a much bigger figure for antivirus software as well as new parts for your desktop.

    How to remove the Officeclicktorun.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 involves the use of specific tool. Appropriate antivirus should have high efficiency at scanning and also be lightweight – in order to create no problems with utilization also on weak PCs. On top of that, it is better to have on-run protection in your security tool – to halt 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 superb option that fits each of the mentioned qualities.3

    Prior to the malware removal, it is important to boot your Windows into Safe Mode with Networking.
