We are sorry that you are having problems with the installation. The TDS GTNXi and any of its files are not viruses, we do not ship anything suspicious.
All the files are checked before being uploaded and additionally we make sure to talk to antivirus companies in order to whitelist our files, by code signing them.
What you are seeing is a false positive and you can easily unlock/set an exception for the TDS GPS Manager, after which you can easily run the program.
Unfortunately this is the case with antivirus software.
If you have additional questions, please email us at: support@tdssim.com
