Windows Defender detects an .exe as Win32/Bitrep.A Trojan?

OK, I had this software(earlier version) on another computer and never had it detected as a Trojan. I tried installing the latest version of this software on my new computer and it got detected as "Win32/Bitrep.A" Trojan after about a week of being installed and Windows Defender deleted it. I tried re-downloading and then scanned the installation exe with Windows Defender and it detected it as the same Trojan. I then tried re-downloading again and Windows Defender deleted it as soon as it finished downloading. The earlier version installation exe wasn't detected as a Trojan. I also tried a update exe to the software that wasn't the same version and nothing was detected. It seems to be with this certain version of the software or the update to this version. The developer recommended installing the free version of Avast. Once installed, I scanned the installation exe with Avast and nothing was detected. Is there a Trojan with the software? According to Windows Defender there is. According to Avast there isn't.

Could be a false positive. You could have tried adding to Window Defender exclusions.

Would be best to thoroughly check for malware just to be sure.

If you need to check for malware here are my recommendations - these will allow you to do a thorough check and removal without ending up with a load of spyware programs running resident which can cause as many issues as the malware and maybe harder to detect as the cause.

No one program can be relied upon to detect and remove all malware. Added that often easy to detect malware is often accompanied by a much harder to detect and remove payload. So its better to be overly thorough now than to pay the high price later. Check with these to an extreme overkill point.

How do I find and remove a virus?

TDSSKiller.exe. - Download to the Desktop - then go to it and Right Click on it - RUN AS ADMIN it will show any infections in the report after running - if it will not run change the name from tdsskiller.exe to tdsskiller.com. Whether it finds anything or not does not mean you should not check with the other methods below.
