EtreCheck produces a comprehensive diagnostic report on the current state of your computer. This report includes details about hardware, installed software, and performance. EtreCheck can find over 50 specific major and minor problems with your computer. EtreCheck can detect issues such as:
- Lack of backup;
- Adware infection;
- Failing hard drive;
- Out of memory situations; and
- Low disk space situations.

EtreCheck will also tell you if you could get improved performance from a new hard drive or RAM upgrade. If EtreCheck finds no problems, it will tell you that too. EtreCheck will help you get your computer healthy again or give it a clean bill of health.

EtreCheck provides:
- A list of major and minor issues;
- Access to security information and adware detection and removal; and
- A text-based report that can be posted on your favourite Internet technical support forum to help people identify what is wrong with your computer.

EtreCheck has been used for years by thousands of people. The EtreCheck report has become an indispensable tool used by both professional consultants and regular people.

EtreCheck's unique adware detection algorithm allows it to work without superuser permissions or even disk access. EtreCheck will never randomly delete files it thinks are adware. Instead, tells you what it finds and lets you make the decision.

In-app purchase:
EtreCheck also provides a Power User in-app purchase that goes beyond the text-based report. It displays a rich, interactive interface that provides links to additional information, charts and graphs, and information to help you learn more about the details of your computer.

If you don't want to post your EtreCheck report publicly, the Power User package can also generate solutions to your computer problems using our AI-driven diagnostic engine. A Solution will include solutions for each major and minor issue, and, in most cases, one or more step-by-step instructions to help you fix your computer problems yourself.

EtreCheck is designed to put you back in control.

Good No-Cost Information Plus a Business Model

The software gives you a good general report for free. You even get security information identifying potential issues for free. The free info is useful if you understand something about computers or know others who can help you, such as those at online forums. The people not understanding this downgrade the software because they want something for nothing. Sure, we all want something for nothing. But how many of us work for free at our primary jobs? Should Etresoft developers work for free? Working for free at your primary job is slavery. Go visit the Amish country of Holmes County Ohio, for example. The Amish use horses to pull their plows. The Amish feed, water, groom and shoe their horses. Think of Etresoft developers a plow horses checking out your Mac. :) Pay the cost if you need the more detailed info. Otherwise, use the free information and be grateful.

Persistent DNS redirection virus

This virus latched onto a program on my MacBook Pro. It prevented my web browser from finding any web site, and prevented my corporate email from connecting to it's server. No other anti-virus detected the problem, or could resolve it. EntreCheck found it on my SyncedTool auto backup app, and I was able to remove the tool and the virus along with it. It also detected a number of other minor problems slowing my system down that I was able to easily fix. My computer is now running smoothly, and virus-free.

Excellent app to diagnose problems

I have a 2011 mac that was starting to have some major issues and Etrecheck confirmed that the HD was failing. Fortunately I had all my Time Machine backups on an external and after installing a new SSD drive and restoring my Mac is almost like new again. This app gives good information for anyone with just a basic knowledge of computers and this combined with some google sleuthing helped save me from having to buy a whole new computer. Thank you to the developers for a great app!
