From your 1st link: Probably harmless! There are strong indicators suggesting that this file is safe to use.
When you use a site like virustotal.com i wouldnt trust some of antivirus programs they list.
I just checked my ahk2exe.exe and it gave the same 2 as you posted.
Never heard of vba32 or zillya most likely cause they are junk AV.
Anyways nothing im worried about its just a false positive.
VirusTotal is detecting a legitimate software I have developed, please remove the detections
VirusTotal acts simply as an information aggregator, presenting antivirus results, file characterization tool outputs,
URL scanning engine results, etc. VirusTotal is not responsible for false positives generated by any of the resources it uses,
false positive issues should be addressed directly with the company or individual behind the product under consideration.
We can, however, help you in combatting false positives.
VirusTotal has built an early warning system regarding false positives whereby developers can upload their software to a private store,
such software gets scanned on a daily basis with the latest antivirus signatures.
Whenever there is a change in the detections of any of your files, you are immediately notified in order
to mitigate the false positive as soon as possible.
