Msftconnecttest not working: when Windows says No Internet access
When msftconnecttest is not working, Windows usually shows No Internet access even though pages may still open.
Microsoft Learn explains that Windows sends a small test request to www.msftconnecttest.com/connecttest.txt and expects the text Microsoft Connect Test. If that answer does not arrive, the network icon reports a problem. Apps such as Outlook, Teams and Windows Update rely on the same result.
To test it yourself, open www.msftconnecttest.com/connecttest.txt in a browser. A page with only the words Microsoft Connect Test means the test address works. If something else loads, such as a login page, an ad or a download offer, the network or a program is changing your traffic. A hotel or airport login page is normal; anything else points to the DNS or proxy hijack described above.
If the test page fails, check the proxy settings and the DNS server addresses in Windows and on the router. Microsoft lists an unknown proxy, a wrong DNS server address and a firewall block as common causes. Microsoft also says not to switch off the connection test to hide the warning. In PowerShell, Get-NetConnectionProfile shows Internet when Windows sees a working connection.

Msftconnecttest redirect: what is it, and how to fix it?
Msftconnecttest redirect is a phenomenon that users are facing for several years now.
According to them, all of a sudden, their Google Chrome, Mozilla Firefox, Safari, MS Edge, or another browser can not correctly connect to the internet, and instead delivers "http://msftconnecttest.com/redirect" error message. Additionally, it was reported that a suspicious connecttest.txt file is attempted to be downloaded. The connectivity issues also prevent users from downloading security software to check the system for malware.
It was reported that the web browsers begin random redirects to msftconnecttest.com, which displays a message asking to download and install an application "COVID-19 Inform App" allegedly developed by the WHO (World Health Organization) to keep up with the coronavirus pandemic.
It is easy to assume that the redirect is not something legitimate and suspicious. It is the case in many situations - the reason is often related to DNS hijacking, where hackers meddle with the router's settings, changing the channels the internet is delivered through. 109.234.35.230 and 94.103.82.249 are known malicious DNS servers used by cybercriminals to deliver fake messages to users.
In other cases, however, Msftconnecttest can relate to legitimate Microsoft domain that regular users should not be able to access, and issues usually arise due to internet connectivity problems or incorrectly set network settings. Regardless of which problem you are dealing with, we provide answers for both situations.

That is Msftconnecttest.com?
Originally, Msftconnecttest.com is a legitimate domain used by Microsoft to send probes to a computer - it shows the connectivity status.
This is done to check whether the machine is actively using the internet or not. If the server receives a failed request via the "Microsoft Connect Test," it warns users about connection problems.
However, those with the suspicious redirect problem will not be rerouted via the official Microsoft IP address but one that is under the attacker's control. As a result, users see a completely different landing address that can be configured by hackers. In some cases,
In 2023, there were no exact details about how attackers managed to gain access to users' routers. However, there have been several reports from the infected users that they did have a Remote Desktop connection open. This way, the attackers can scan the internet and access the router or computer via the default port. Thus, to mitigate this attack, you should never leave your RDP visible.
Those who are affected by the Msftconnecttest redirect hijack will not see the official MSN.com or any other website for that matter. Instead, they will be shown a suspicious notification that reads:
It is not a surprise that this scam is not the only one that attempts to push malware through fake emails, ads, and redirects, which allegedly provides information on the coronavirus pandemic situation. Malicious actors want to abuse the concerns about the global crisis - ransomware attacks have plagued the health sector, despite the increasing workloads.
Those who get tricked by this message and downloads the alleged COVID-19 app, instead infect their machines with Oski Trojan. This malware can steal a variety of information once installed, including browser cookies, login credentials, F2A databases, text files, crypto wallets, and more.
As a result, the infected users can suffer serious privacy issues to the point where they could lose their identity. Therefore, it is important to stop the redirect and never download anything offered.
In case malware was indeed installed, Msftconnecttest redirect removal should be first performed with powerful anti-malware, such as or . Since a Trojan infection can seriously impact system files, resulting in crashes and other stability issues, experts also recommend using to fix virus damage.

DNS hijacking - a rather rare but dangerous practice
DNS hijacking is something that does not come along often, although tools like DNS Unlocker has caused major issues to users in the past.
DNS, or a Domain Name System, is users to convert IP addresses into domain names - it would not be possible to access any website by typing in an URL without it. In other words, you would have to know the IP address of every website to visit it (a real pain, indeed).
DNS address can be provided by your ISP or set to come from another provider, such as Google. By using different DNS, you can bypass certain restrictions. On the contrary, cybercriminals might use this practice in order to restrict their internet access, deliver intrusive advertisements, or redirect them to malware-laden websites.
In most cases, the malware installed on the computer behind users' backs is the culprit of unsolicited changes made to DNS servers. Nonetheless, the attackers can access router settings via other channels, such as RDP or unprotected WiFi connection.
Thus, be careful with potentially unwanted programs, as they might change DNS settings without permission. When installing new apps/freeware from third parties, always pick Advanced/Custom installation settings when prompted, decline all the offers, read the fine print, and remove all the ticks from pre-checked checkboxes.

Deal with suspicious redirects
Msftconnecttest redirect removal is necessary not only for the normal operation of the computer but also for your own safety.
There are several steps that you can take to do that, although the most important thing is to eliminate the Oski Trojan if such was installed on your system. In case you experience crashes, errors, and other Windows issues, you can employ to fix them automatically.
Once you are sure that the malware is eliminated and your computer is clean, you should then remove Msftconnecttest redirect problems. First of all, you need to ensure that you delete the DNS settings applied by the attackers.
To do that, you can either reset your network components or change the DNS manually (alternatively, you can access your router's Administrator's panel) and change the settings from there. Here's how to do that:
Once you change the DNS settings, you should reboot all your devices connected to the network, including gaming consoles, laptops, tablets, phones, etc. Finally, you should reset all the installed web browsers, change all the passwords for all your accounts, employ a secure password-managing app, and enable two-factor authentication where possible.
Other ways to fix the issue that could be useful if your DNS was already correct and no proxy was set up before:
- Right-click on Start and select Settings
- Go to Network & Internet and select Ethernet on the left
- On the right, pick Change adapter options
- Right-click on your connection and select Properties
- Select Internet Protocol Version 4 (TCP/IPv4) and pick Properties
- Check Obtain DNS server automatically and click OK.
- Check your network settings on your device and ensure that the correct network is selected and that the settings are correct.
- Disconnect and reconnect to your network.
- Restart your router or modem.
- If the problem persists, contact your internet service provider or a technical support representative for assistance in resolving the issue.
Questions about Msftconnecttest redirect ads
What is msftconnecttest.com?
Msftconnecttest.com is a legitimate domain originally used by Microsoft to send connectivity probes to your computer. When your system accesses this domain, Microsoft's servers receive a response indicating whether your internet connection is active. The legitimate purpose is to detect and alert you to connectivity problems.
However, hackers have hijacked this domain through DNS poisoning attacks. They redirect msftconnecttest.com requests to malicious IP addresses (like 109.234.35.230 or 94.103.82.249) under their control. Users are shown fake COVID-19 app installation pages or other malicious content instead of legitimate connectivity checks.
Is the COVID-19 app offer real?
No. The "COVID-19 Information App" offered on fake msftconnecttest pages is a scam designed to trick you into downloading malware. The pages falsely claim the app comes from the World Health Organization (WHO) and provides coronavirus information. In reality, downloading and installing the app infects you with Oski Trojan malware.
Oski steals passwords, login credentials, cryptocurrency wallet information, browser cookies, and F2A authentication databases. The WHO and legitimate organizations never distribute apps through malicious redirects. If you want official COVID-19 information, visit official government or WHO websites directly.
How did I get the msftconnecttest redirect?
Your router or computer DNS settings have been hijacked through DNS poisoning. Attackers typically gain access via weakly protected Remote Desktop (RDP) connections left open on your network. Once inside, they modify your router's DNS settings to redirect all requests to msftconnecttest.com toward malicious servers.
Some users had RDP connections visible on the internet using default ports, making it easy for attackers to scan and access their systems. In rare cases, malware on your computer changes DNS settings directly. Your internet service provider's DNS may also be compromised in widespread attacks affecting multiple users.
What can the attacker do with access to my router?
DNS hijacking allows attackers to redirect any website request to malicious pages they control. You cannot safely access any website because even legitimate addresses could route to fake login pages or malware sites. Attackers can block your access to antivirus websites, making it difficult to download security tools and clean your system.
They can intercept your browsing traffic, capturing passwords and personal information. Remote access to your router lets them monitor all device activity on your network. In worst cases, they use the compromised network as a launching point for attacks against other systems, making your router an accomplice in cybercrime.
How do I know if I have this problem?
You have a DNS hijacking problem if accessing any website redirects you to msftconnecttest.com with a suspicious COVID-19 app offer, or if you cannot access any websites normally. Your browser may show error messages about connection failures even though your internet connection works. A suspicious file called connecttest.txt may be automatically downloaded.
You might experience intermittent connectivity or inability to reach certain sites while others load. Run the steps below to check your DNS settings. If your computer's DNS settings are correct but the problem persists, your router's DNS has been hijacked.
What is DNS and why does hijacking matter?
DNS (Domain Name System) translates website addresses like google.com into IP addresses that your computer actually uses to connect. Without DNS, you would need to memorize every IP address to visit websites. By hijacking DNS, attackers can make typing google.com connect you to a fake website instead, stealing your login credentials.
They can block access to security websites so you cannot download removal tools. DNS hijacking is more dangerous than malware because it compromises everything you do online at the network level. Even if your computer is clean, the hijacked DNS still redirects all your traffic to attacker-controlled pages.
How do I fix the DNS hijacking?
Reset your DNS settings by right-clicking Start, selecting Settings, going to Network & Internet, selecting Ethernet on the left, clicking Change adapter options, right-clicking your connection, selecting Properties, choosing Internet Protocol Version 4 (TCP/IPv4), clicking Properties, and checking Obtain DNS server automatically. Click OK and reboot.
Alternatively, access your router's administrator panel directly (typically 192.168.1.1 in your browser), log in with admin credentials, and reset the DNS settings to automatic or your ISP's default DNS servers. If you do not know your admin password, perform a factory reset on your router. After changing DNS settings, reboot all your devices connected to the network.
What if I downloaded the COVID-19 app and installed it?
Scan your entire system immediately with reputable anti-malware software to detect and remove Oski Trojan and any other malware installed. Download the latest version of security tools from a clean device if necessary. Run a full system scan and allow the tool to remove all detected threats.
Change all your passwords for every online account, especially email, banking, and social media, because the malware may have stolen them. Monitor your bank and credit accounts for unauthorized transactions. Consider placing a fraud alert with credit bureaus.
Enable two-factor authentication on all important accounts. Check your router password and wireless network settings to ensure attackers did not modify them. Replace your RDP password if you have Remote Desktop enabled.
Will Fortect remove Msftconnecttest redirect?
Fortect scans Windows for malware and unwanted programs and repairs the system files and settings they change, and its free scan shows what it finds on your PC before you decide anything.
For Msftconnecttest redirect, follow the plan above as well: the browser steps take back permissions and settings that no scanner treats as a threat, and uninstalling the program that brought it removes the source.
Run Microsoft Defender's full scan and, if anything was found, its offline scan as a second opinion. If the symptoms are gone after the plan and both scans are clean, there is nothing more to do.
