Malware removal

Disclaimer:
The following instructions are recommendations only. You take full responsibility for any steps you choose to perform on your computer. While the following recommendations are performed without issue on countless machines, there is always a risk of damaging your Operating System or experiencing data loss on any machine. It is solely YOUR responsibility to save all work and back up any and all important data on your system before proceeding.
Malware Remediation Steps:
Before proceeding, go into your browser’s extensions and remove all suspicious items. Also go into your browser’s settings and remove any default search providers and unusual homepages. If you are unsure how to do this, proceed to Step 1.
Download and run the following tools in this order. Run all tools unless otherwise instructed. All tools should be run in Normal Mode (not Safe Mode) unless you are unable to boot Normal Mode, or the scans fail in Normal Mode. All tools must be run under an Administrator account. Do not remove any tool-generated logs in the event a helper needs you to post them to further assist you.
1) Run rkill.com. Sometimes it takes a few minutes to finish. Do not reboot when done.
* Kills running malicious processes
* Removes policies in the registry that prevent normal OS operation
* Repairs file extension hijacks
2) Download an updated copy Malwarebytes 4.0. Turn on the “Scan for Rootkits” option. Then, run a “Scan”
* Successfully removes the vast majority of infections
* Has an industry-leading, lightning fast scanning & heuristics engine
* Has built-in repair tools to fix damage done by malware
3) Run Malwarebytes ADWCleaner 8 using the “Scan Now” button.
* Removes majority of adware, PuPs, Toolbars, and Browser hijacks
* Scans for bloatware & pre-installed sofware and lets you quarantine any or all of it.
* Fixes proxy settings changed by malware
* Removes certain non-default browser settings
Optional, Advanced Step (only run if previous tools fail to solve problem):
4) Run Sophos HitmanPro
* Here is HitmanPro.
HitmanPro is a phenomenal "second-opinion" malware scanner. I recommend clicking "Settings" and uncheck "Scan for tracking cookies" before starting the scan. This will drastically reduce scan times. This tool can only be run ONCE for free. Use it wisely.
Please note: If malware has prohibited you from browsing the web or downloading files, you can try running the NetAdapter Repair Tool with all options checked which will attempt to restore your internet connection & default browser settings. You may have to download these tools on another computer and move them to a flash drive that you can plug into the infected machine.
Think your Mac is infected?
Try Malwarebytes Anti-Malware for Mac. Please make a post if it is unsuccessful.
If you have run all of the above tools successfully, you should be malware-free. If you are still experiencing problems, please make a post in r/techsupport for further assistance.
Follow-up Steps (highly recommended):
* Using a computer that has not been infected, change passwords to all your online accounts.
* Consider enabling two-factor authentication on all accounts!
* Install a better anti-virus. See recommendations below.reddit.com, user cuddlychops06, "7 years ago" as of Apr 15, 2022.
