Anti-Virus Software
It is not necessarily more likely for an EXE installer to be blocked by antivirus than an MSI installer. Antivirus software typically works by scanning files and identifying potential threats based on certain characteristics or patterns. Both EXE and MSI installers are executable files that can potentially contain malicious code or behaviors, so they may be flagged by antivirus software if they are identified as a potential threat.
That being said, some antivirus software may have different default settings or scanning strategies for different types of files. For example, some antivirus software may be more likely to scan and block EXE files by default.
In general MSI installers are less likely to be blocked compared to EXE installers.
NSIS (Nullsoft Scriptable Install System) is a popular open-source software installer that allows developers to create custom installers for their software. However, NSIS installers are sometimes blocked by antivirus software because they can potentially be used to distribute malware or other malicious code.
NSIS
One reason NSIS installers may be blocked is because they can execute arbitrary code during installation, which makes them more difficult to analyse and potentially more vulnerable to exploitation by attackers. Additionally, some attackers may use NSIS installers to package malware or other malicious code, and antivirus software may be programmed to block or flag NSIS installers as a precaution.
And, because NSIS installers have been used to distribute malware in the past, some antivirus software may be more likely to flag or block them as a precaution.
