Is officec2rclient.exe safe?
If we’re talking about the genuine officec2rclient.exe, it certainly doesn’t pose any security threat since it’s a software component signed by Microsoft Corp. But before you dismiss this type of treat, keep in mind that nowadays most successful malware manages to avoid detection by posing as trusted processes. Since officec2rclient.exe is a perfect target for these types of malware executables, we encourage you to perform a series of investigations that will help you determine if the process that you’re looking at is genuine or not. First things first, you should start investigating the parent application. Keep in mind that unless you’re actively using a Microsoft365 subscription, there’s no reason why you should see the officec2rclient.exe inside your Task Manager. If you do see it despite not having a Microsoft365 subscription membership, the chances of dealing with malware are high. If the first investigation wasn’t that eye-opening, you should concentrate on the location of the officec2rclient.exe via Task Manager. To do this, press Ctrl + Shift + Enter to open up a Task Manager window. Once you manage to get inside Task Manager, select the processes tab from the horizontal menu, then scroll down to the list of Background processes and locate officec2rclient.exe. After you manage to locate it, right-click on it and choose Open File Location from the newly appeared context menu. If the revealed location is different than “C:\Program Files\Common Files\Microsoft Shared\ClickToRun” and you didn’t install the suite in a custom location, the chances of dealing with suspicious files are high. If you’re suspecting that you might be dealing with a virus, you should upload the officec2rclient.exe file to a virus signature database to verify if the file is indeed malicious or not. If you’re looking for an easy and efficient way to do this, we recommend VirusTotal. To do this, access this link (here) and wait for the analysis to complete. Note: If the analysis has revealed that the officec2rclient.exe file is genuine, skip the next section and move directly to the ‘Should I Remove officec2rclient.exe?’ section. However, if the VirusTotal analysis has revealed some inconsistencies, continue with the next section below for some step-by-step instructions on dealing with the virus infection.
Dealing with the security threat
If the investigations you performed above have revealed that the officec2rclient.exe process is located in a suspicious location and VirusTotal labeled it as a security suite, ti’s mandatory that you deploy a security scanner capable of identifying the virus infection and dealing with it swiftly. Keep in mind that if this scenario is true (and you’re indeed dealing with a malware that’s using cloaking to avoid detection), not all security suites will be able to detect and eliminate the threat. Since not all security suite will be able to detect and quarantine malware of this kind, you will either need to use a premium scanner or you’ll need to deploy a quality free antimalware scan. If you already pay a premium subscription for an AV product, you can initiate a scan with that, but if you’re trying to avoid spending money for a security scanner, we recommend a deep scan with Malwarebytes. This operation will allow you to remove the majority of malware products that are avoiding detection by posing as processes with enhanced privileges. If you’re unsure of how to initiate a deep scan with Malwarebytes, follow this step-by-step article (here). In case the scan managed to identify and quarantine infected items, restart your computer, then move down to the next section below and see if the officec2rclient.exe process is still appearing with high resource consumption.
