GlassWire FAQ

Frequently asked questions.

Why is GlassWire flagging itself as malware under the VirusTotal column?

GlassWire itself may occasionally be flagged as malware by VirusTotal as a false positive. If you have any concerns about this please email us, or post in our forum so we can help you.

Why does Windows Defender sometimes show a GlassWire Firewall rule as a trojan?

The Microsoft Windows Defender software does not like to be blocked from updating, and if it is blocked by GlassWire at the same moment it is initiating a scan of your PC it can give off a trojan warning (with something like win32/BlockMsav.A!.reg). To avoid the problem you can unblock Windows Defender under GlassWire's Firewall tab.

Can I use GlassWire for free, and what are GlassWire's free features?

GlassWire 2.0 comes with a free 7 day trial so you can try out all its paid Basic, Pro, Elite features. After 7 days GlassWire will revert to its free version. The free version of GlassWire includes its extreme network monitoring functionality where you can see your live and past network activity in detail. You can also set Data Alerts to stay under your data limits, and scan your network related apps with VirusTotal. GlassWire's free version also allows you to monitor one PC remotely. The free version of GlassWire has no firewall functionality, and none of our security features are activated with the free version of GlassWire. Buy GlassWire now to upgrade to its paid version.

Why does my app still connect to the network while in “Ask to connect” mode?

Sometimes apps will briefly access the network with GlassWire for Windows if there was a previous “allow” rule added directly to the Microsoft Windows Firewall. We at GlassWire use the Windows Firewall API to allow or deny connections because it uses less CPU/Memory for your PC, and because it’s a transparent way for our users to see what we’re doing on their computers.

If you want to avoid any apps connecting to the network while in “Ask to connect” mode you can reinstall GlassWire choosing the GlassWire installer option to reset the Windows Firewall to its defaults. While doing so you can also choose to reset GlassWire’s settings to its defaults if you’d like to do that. Resetting GlassWire to its defaults will not cause your paid software to become deactivated.

Why does GlassWire for Android need the “phone” permission to make phone calls?

One of the first permissions GlassWire asks for is the “Phone” permission. Some people have asked us why GlassWire needs the ability to make phone calls, and of course GlassWire does not make phone calls with your phone. So why does GlassWire need the “phone” permission? The Android OS requires this “phone” permission for us to see mobile network data for your phone. Without this permission we are unable to see your phone’s mobile data usage.

Please note GlassWire cannot see your app/data usage even if we wanted to because our app does not access the network or transfer any data itself. Check GlassWire's privacy policy to see how we are an ad-free tracking-free app.

Who makes GlassWire?

GlassWire was created by Jon Hundley and a team of indie developers to help people secure their computers and phones. We wanted to create a tool that helped people easily see what their devices were doing in the background over the network. Check out this Fast Company article to learn more about the team behind GlassWire.

What does it mean if GlassWire alerted me to a "Suspicious host connection"?

Don't panic. It's possible to connect to a suspicious host or domain with no consequences. If GlassWire alerted you to a suspicious host connection there are several things you can do. First scan the item that connected to the suspicious host for viruses by going to the "alerts" tab and finding the suspicious host alert. Click the icon of the application that contacted the suspicious host and then click "virus scan" inside that window. Next try a full system antivirus scan with your up to date antivirus software to see if it picks up anything suspicious. If everything looks OK with the two scans you can visit a website like Site Advisor or Web of Trust and type in the suspicious domain to see if you can find out more data about why it may be suspicious. Go to the GlassWire Firewall tab and consider blocking the application temporarily while you do more research. If you're still feeling nervous post screenshots to our forum and get feedback from other GlassWire users.

Why didn't GlassWire show one of my applications on the graph or as a "new" connection?

To catch all network connections the GlassWire installer recommends you reboot after installation. However we do realize most people hate rebooting so we don't force you to do so.

What is gwinstst.exe?

On install GlassWire let's us know how many installs of our software we are getting by briefly letting know about the installation. We are looking at more transparent ways to track installs in the future. We would feel very frustrated if we were unable to track our installs, it's kind of like having a web page and not knowing if anyone is visiting it.

Why does GlassWire connect to

GlassWire is checking for software updates and suspicious host updates. If you block GlassWire from accessing the network then you will not know about new versions of our software that contain security and bug fixes.

Can I use GlassWire to monitor remote computers and servers?

Yes. Check out this section of our user guide for more information.

Can I use GlassWire as my only antivirus?

No. GlassWire works in addition to your antivirus as added protection but we do not recommend it as a stand-alone way to protect your computer.

Do you monitor my network activity?

No. Your network activity is stored on your computer and only you can access it. If you don’t want to keep your network activity you can also go to the top left "GlassWire" menu and choose "Incognito" or go to your settings to delete all your network history any time. One of the useful features of GlassWire is the ability to go back and time and see your network activity so we don’t recommend always using Incognito mode. Check GlassWire's privacy policy to see how we are an ad-free tracking-free app.

Is it possible to disable the desktop alerts?

Yes. Go to the top left GlassWire menu and choose "snooze alerts" to disable them for 24 hours or go to the settings under "Client" to disable them permanently.
