Scan For Viruses
GlassWire works with your antivirus application. First open your antivirus application and then make sure its definitions are up to date. Next click the "virus scan" button in GlassWire next to the application or file you are concerned about. If your virus scan still shows no problem then it may be time to try a full system scan.

Don't run the default system scan which may miss some important parts of your PC. Be sure the application you are using is doing a full system scan and it's checking every part of your computer including your hard drive, connected storage, your master boot record, boot sector, and any applications running in the memory.

If you have no antivirus installed or if you're unhappy with your current antivirus it may be worth trying Microsoft's Security Essentials if it’s not installed on your computer already HerdProtect is another security application that is powered by over 60 different anti-malware engines that may be able to find something your single antivirus application missed.
