![]() I have considered making an Audit only fixlet to point out that software that bundles Adware is detected if a system is relevant to it, but that is also complicated. We have NOT created update content for software that bundles Adware in it because that is not great, but if you have that software installed in your environment, then you most likely already have the Adware they bundle installed. We are doing some validations on our end, but it is hard for us to be certain something is benign. We can only assert that our prefetches and hash checks prevent the file from being modified between you and the vendor as long as our hashes match the official installer. If you feel that Putty is malicious, then you would need to investigate every system that our fixlet is relevant on already because they already have it installed, just an earlier version. We are just providing a mechanism to upgrade it to the newest version. ![]() ![]() There is an added part to all of this, because these are upgrade fixlets, they are only relevant on systems that already have Putty installed, so if you already have Putty installed, and Putty is bundling malicious code in it’s binaries and has been for a while now, then you already have that malicious code on your system. I would expect the EXE inside the MSI to be flagged as malicious and if the MSI is flagged as malicious, then it would only be because it contains a malicious EXE. I vouch that this is not doing anything malicious, but you do not have to take my word for it, just go and inspect every aspect of it, it's all available.I do wonder if Putty itself is actually what is being considered malicious since it could be used as a hacking tool? Not that it contains malicious code, but that it being present at all could be the sign of something malicious? I say this because it seems like it is the MSI itself that is getting flagged as malicious, which seems dubious. Also, the source code is always available for everything in the release, so you have all the tools necessary to make an informed decision. The public releases are never files compiled on my own computer, but rather built in a clean environment set up by GitHub. To mitigate any potential risk of my development machine being compromised, the program files that you download are built automatically on GitHub's infrastructure. I personally cannot do anything regarding how some other products decides to flag a particular 3rd party file. There are numerous threads where people are discussing this from time to time, like this one where people discuss this. Thus, this patcher falls in the category of false positives: your antivirus thought such a program was not something you meant to run, but that's not the case this time. presented in this paper, there is a high possibility that original and legitimate applications will most likely produce a number of alerts, false positives, similar to those seen in malicious software, when scanned by AV products. One such kind of legitimate programs is this patcher, that you deliberately choose to run and let it alter Explorer's code and memory in a controlled manner so that you achieve a certain effect. Antivirus False-Positive Alerts, Evading Malware Detection, and Cyber-security Issues. Injecting code into other executable programs is rarely done by legitimate programs. That means that the antivirus program thinks that due to the nature of the code in this application, it likely may be a virus, a program that the user does not really mean to run. Python is usually exempt from this because most antiviral software doesnt understand that Python code is still code and is therefore dangerous but, now that youre entering executable territory, youre also leaving behind the happy little AV free bubble that interpreted. The program being flagged is usually done through heuristic analysis, not via a database of know viruses. Antiviral false positives are a common theme in distributing software. This is fairly normal, a sign that the product you are using is decently capable, since it features detection methods a bit more advanced than what was state of the art in 1999. ![]() Files up to 650 MB can be uploaded to the website, or sent via email (max. The file that you download may trigger a false positive alert in your antivirus program. or to verify against any false positives. ![]()
