how Combo Cleaner works<\/a>. If the utility spots malicious code, you will need to buy a license to get rid of it.<\/sub><\/div>\nGoogle Chrome Helper (Renderer), in its turn, is responsible for displaying web content, such as HTML, CSS, JavaScript, and media, within individual tabs or windows. In case you didn\u2019t know, each tab in Chrome typically runs as a standalone process isolated from others. This \u201csandboxing\u201d principle prevents a buggy web page from crashing all the open tabs and enhances security by limiting the damage that potential malware could cause. The \u201crenderer\u201d label means the item focuses on the heavy lifting of turning code into visuals you see on the screen.<\/p>\n
As counterintuitive as it may sound, these intrinsically useful processes can backfire on a Mac\u2019s productivity instead of optimizing the browser\u2019s work and thereby limiting the performance hit system-wide. Now let\u2019s look at the common triggers for excessive CPU and memory consumption by these entities on a Mac.<\/p>\n
Possible causes for the Google Chrome Helper (Renderer) issue<\/h3>\n The issue often kicks in when too many tabs are loaded. As previously mentioned, this condition spawns multiple instances of the Google Chrome Helper (Renderer) process, and at some point, their cumulative usage of the computer\u2019s resources skyrockets. This outcome is particularly likely if dozens of tabs are open at the same time. A similar predicament occurs when several resource-intensive extensions are running concurrently. And if both tabs and extensions are excessive, the situation develops into a cascading effect that depletes the processing power under the Mac\u2019s hood.<\/p>\n
Inadequately optimized web content is another likely culprit. Some websites include heavy JavaScript, redundant animations, or videos that play automatically without user action. In this case, the Renderer process works overtime to keep up with the content, which cranks up CPU usage. To top it off, even if a tab isn\u2019t active, extensions or pages with background scripts may keep their helper processes running.<\/p>\n
An outdated version of Chrome might be to blame as well, because it can handle helper items inefficiently. Bugs or macOS compatibility issues can throw another spanner in the works, especially after a system update. One more factor that exacerbates the problem is a malfunctioning hardware acceleration, which Chrome uses to offload rendering tasks to the Mac\u2019s GPU.<\/p>\n
First steps to diagnose and fix Google Chrome Helper CPU depletion<\/h3>\n The response to these scenarios is a trial-and-error type of thing. For a start, I recommend entry-level techniques like closing unnecessary tabs and checking for a browser update. If none of this addresses the issue, proceed to the steps below.<\/p>\n
\nTidy up your Chrome extensions<\/strong><\/li>\n<\/ol>\n\nOpen the Customize and control Google Chrome<\/strong> drop-down menu, click on Extensions<\/strong>, and select Manage Extensions<\/strong> as illustrated in the screenshot.<\/li>\n<\/ul>\n\nLook over the list of your installed extensions, and if there are ones that you no longer need, get rid of them by clicking the Remove<\/strong> button next to them.<\/li>\n<\/ul>\n\nRestart Chrome and see if this has fixed the bug.<\/li>\n<\/ul>\n\nTurn off graphics acceleration<\/strong><\/li>\n<\/ol>\n\nSelect Settings<\/strong> in the Customize and Control Google Chrome<\/strong> menu.<\/li>\n<\/ul>\n\nClick on System<\/strong> in the sidebar and switch the \u201cUse graphics acceleration when available\u201d toggle to an Off position. Click the Relaunch<\/strong> button so that the change takes effect.<\/li>\n<\/ul>\nManual removal of Google Chrome Helper (Renderer) high CPU virus<\/h2>\n The steps listed below will walk you through the removal of this malicious application. Be sure to follow the instructions in the specified order.<\/p>\n
\n\nExpand the Go<\/strong> menu in your Mac\u2019s Finder bar and select Utilities<\/strong> as shown below.\nLocate the Activity Monitor<\/strong> icon on the Utilities screen and double-click on it.\nIn the Activity Monitor app, look for Google Chrome Helper<\/strong>, Google Chrome Helper (Renderer), Google Chrome Helper (Plugin), Google Chrome Helper (GPU)<\/strong>, or another process that appears suspicious. To narrow down your search, focus on unfamiliar resource-intensive entries on the list. Keep in mind that its name isn\u2019t necessarily related to the way the threat is manifesting itself, so you\u2019ll need to trust your own judgement. If you pinpoint the culprit, select it and click on the Stop<\/strong> icon in the upper left-hand corner of the screen.\nWhen a follow-up dialog pops up asking if you are sure you want to quit the troublemaking process, select the Force Quit<\/strong> option.<\/p>\n\nClick on the Go<\/strong> menu icon in the Finder again and select Go to Folder<\/strong>. You can as well use the Command-Shift-G<\/strong> keyboard shortcut.<\/p>\n\nType \/Library\/LaunchAgents<\/strong> in the folder search dialog and click on the Go<\/strong> button.<\/p>\n\nExamine the contents of the LaunchAgents folder for dubious-looking items. Be advised that the names of files spawned by malware may give no clear clues that they are malicious, so you should look for recently added entities that appear to deviate from the norm.<\/p>\n
As an illustration, here are several examples of LaunchAgents related to mainstream Mac infections: com.pcv.hlpramc.plist<\/strong>, com.updater.mcy.plist<\/strong>, com.avickUpd.plist<\/strong>, and com.msp.agent.plist<\/strong>. If you spot files that don\u2019t belong on the list, go ahead and drag them to the Trash.<\/p>\n\nUse the Go to Folder<\/strong> lookup feature again to navigate to the folder named ~\/Library\/Application Support<\/strong> (note the tilde symbol prepended to the path).<\/p>\n\nWhen the Application Support directory is opened, identify recently generated suspicious folders in it and send them to the Trash. A quick tip is to look for items whose names have nothing to do with Apple products or apps you knowingly installed. A few examples of known-malicious folder names are UtilityParze<\/strong>, LinkBranch<\/strong>, SystemSpecial<\/strong>, and IdeaShared.<\/strong>\nEnter ~\/Library\/LaunchAgents<\/strong> string (don\u2019t forget to include the tilde character) in the Go to Folder<\/strong> search area.<\/li>\n<\/ol>\n\nThe system will display LaunchAgents residing in the current user\u2019s Home directory. Look for dodgy items related to rogue mds_stores process (see logic highlighted in subsections above) and drag the suspects to the Trash.Type \/Library\/LaunchDaemons<\/strong> in the Go to Folder<\/strong> search field.<\/li>\n<\/ol>\n\nIn the LaunchDaemons path, try to pinpoint the files the malware is using for persistence. Several examples of such items cropped by Mac infections are com.pplauncher.plist<\/strong>, com.startup.plist<\/strong>, and com.ExpertModuleSearchDaemon.plist<\/strong>. Delete the sketchy files immediately.<\/li>\n<\/ol>\n\nClick on the Go<\/strong> menu icon in your Mac\u2019s Finder and select Applications<\/strong> on the list.<\/li>\n<\/ol>\n\nFind the entry for an app that clearly doesn\u2019t belong there and move it to the Trash. If this action requires your admin password for confirmation, go ahead and enter it.Expand the Apple menu and select System Preferences<\/strong>.Proceed to Users & Groups<\/strong> and click on the Login Items<\/strong> tab.Now select Profiles<\/strong> under System Preferences. Look for a malicious item in the left-hand sidebar. Several examples of configuration profiles created by Mac adware include TechSignalSearch<\/strong>, MainSearchPlatform<\/strong>, AdminPrefs<\/strong>, and Chrome Settings<\/strong>. Select the offending entity and click on the minus sign at the bottom to eliminate it.<\/li>\n<\/ol>\nGet rid of resource-intensive malware in web browser on Mac<\/h2>\n To begin with, the web browser settings taken over by the virus exploiting Google Chrome Helper (Rende process should be restored to their default values. Although this will clear most of your customizations, web surfing history, and all temporary data stored by websites, the malicious interference should be terminated likewise. The overview of the steps for completing this procedure is as follows:<\/p>\n
