Question: Q:
Remove “” Malware in Chrome?

iMac (Retina 5K, 27-inch, Late 2015), 3.3 GHz Intel Core i5, 16 GB 1867 MHz DDR3, 1.7 TB free — Running High Sierra 10.13.6 (17G65). For a variety of reasons, Chrome is my default browser, and Google is my default search engine and homepage. While browsing with Chrome two days ago, I made the idiotic mistake of clicking on a Flash download popup and immediately noticed signs of infection by this malware. The main only noticeable effect is that my homepage, tab option, and search engine in the Chrome browser now default to this alien “” search engine, which produces results very different from Google’s. I’ve tried three long phone troubleshooting sessions with Apple Help, including downloading and scanning with Malwarebytes, which read my computer as “clean.” Also pursued other remedial steps I’ve seen suggested in other websites. (Although there are only a few that deal specifically with Chrome on Mac.) Uninstalled Chrome application, including trashing all its support folders from Library. However, the bug still keeps coming back. The “good” news is that Safari (so far) shows no sign of the infestation — so I’m using that as my only browser. However, I don’t want my (still relatively new) iMac to go through the rest of its life with this alien entity ticking away in its innards. Can anyone here recommend a more permanent solution to my problem? Is there a third-party malware removal product that’s both effective and trustworthy? Thanks in advance for any help.

Other reports also stated that the victims have had tough time removing from their devices:

It appears that the “virus” changes a group of Chrome policies with the idea to set a new default homepage and new tab page, as well as modify the browser’s settings. According to a discussion, you can see your current Chrome policies by typing chrome://policy/ into the URL bar. In case you’re affected, you should be able to notice the modifications of your policies immediately.

The advice here is to utilize the command line to delete or modify the affected policies by opening up “Terminal” and copying each of the following entries below:

defaults write HomepageIsNewTabPage -bool false

defaults write NewTabPageLocation -string “”

defaults write HomepageLocation -string “”

defaults delete DefaultSearchProviderSearchURL

defaults delete DefaultSearchProviderNewTabURL

defaults delete DefaultSearchProviderName
