It is a false positive. Some Anti Virus reports them as trojan/malware/riskware, it happens for Electrum also.

For extra security you can verify the PGP signature for that file (It is signed with mine PGP key):
Verify the signature of what you have downloaded by using the file signature:
https://github.com/Groestlcoin/electrum-grs/releases/download/v3.3.8/electrum-grs-3.3.8-setup.exe.asc
and my (signer) public key:
