MT AI Engine · Verdict analysis

The reasoning behind this verdict

Analyst conclusion

Twenty-six of the 71 antivirus engines that checked it flag this file. Five major antivirus engines, including BitDefender, ESET, Microsoft and Symantec, name the OfferCore bundler family. It carries a valid signature from Infivora, but all 11 earlier files from that publisher were flagged. In testing it fetched remote content from a cloud host, which fits an installer that downloads third-party offers.

Where this verdict could be wrong1 caveat
  • Several major engines (ESET, Microsoft, Kaspersky, Malwarebytes) label it as a potentially unwanted bundler rather than a trojan, and the sandbox runs recorded no malicious verdict, injection or persistence.

These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

What the test run showed

What the file did on a test computer

Confirmed in the test run

  • Moderate concern: Contains packed or scrambled code that is harder to inspect (common in installers too).

  • Note: Read the user name of the test computer.

  • Note: Deleted files or logs during the test run (installers often clean up after themselves).

  • Note: Talked to servers over the internet during the test run.

  • Note: Read basic details of the test computer, such as its Windows version.

  • Note: Loaded extra code modules while running.

Sandbox labels we could not confirm (common in safe files too)

  • Not confirmed: A sandbox rule tagged this run as code injection, but no injected program was recorded.

  • Not confirmed: A sandbox rule tagged this run as changing how Windows loads code; nothing confirms it.

This file was run on a test computer (a sandbox), not on yours. Labels we could not confirm are listed so you can see them, but they are not treated as evidence against the file.

Threat context

How bundlers and adware work

This is a bundler: a real-looking installer that hides extra software inside. When you run it, it installs things you never asked for, such as ad injectors, browser toolbars or fake 'PC cleaner' apps. The people behind it get paid for every app it installs.

Bottom line:It is not usually built to destroy files, but it slows the PC, floods it with ads and can be hard to remove completely.

Questions & answers

Short answers to the 9 questions people ask most about this file.

Is Yz7k7ivGt.exe a virus?
Yz7k7ivGt.exe is not a virus, but it is unwanted software (adware or a bundled program). Don't run it. Delete it, then empty the Recycle Bin. 26 of the 71 antivirus engines that checked it flag it, most as OfferCore. If you've already run it, see the removal steps below.
What is Yz7k7ivGt.exe?
Yz7k7ivGt.exe is a Windows program, about 16.2 MB. Its version information says it is “MECHA MANGA - FZCO, OOO Download Manager” (MECHA MANGA - FZCO, OOO). The digital signature from Infivora checks out. VirusTotal first saw it on Oct 22, 2026.
How many antivirus engines detected Yz7k7ivGt.exe?
26 of the 71 antivirus engines that checked it flag Yz7k7ivGt.exe, including Microsoft and Kaspersky. We weigh which engines flagged it and what else the scan found, not just the count. The rating comes from all the evidence together, not from this count alone.
What should I do if I already ran Yz7k7ivGt.exe?
1) Uninstall it, and any program you don't recognise that arrived at the same time, from Settings > Apps (or Control Panel > Programs). 2) Remove browser extensions you didn't add and reset your browser's home page, new-tab page and search engine if they changed. 3) Run a scan with your antivirus to catch anything bundled with it. It is unwanted software rather than an infection, so you don't need to disconnect the device, change passwords or reinstall anything unless the scan finds real malware.
How do I remove Yz7k7ivGt.exe?
To remove Yz7k7ivGt.exe: 1) uninstall it from Settings > Apps (or Control Panel > Programs), together with anything installed alongside it. 2) Remove unfamiliar browser extensions and reset browser settings it changed. 3) Delete it, then empty the Recycle Bin. 4) Run a scan with your antivirus and remove what it finds.
What kind of program is Yz7k7ivGt.exe?
Antivirus engines classify Yz7k7ivGt.exe as unwanted software: adware or a bundled program that installs things you didn't ask for. Engines attribute it to the OfferCore family.
Is Yz7k7ivGt.exe digitally signed?
Yes. Yz7k7ivGt.exe has a valid digital signature from Infivora, which shows the file hasn't been changed since that publisher signed it. Malware is sometimes signed with stolen certificates, so a signature alone isn't proof of safety.
What is the SHA-256 hash of Yz7k7ivGt.exe?
The SHA-256 fingerprint of Yz7k7ivGt.exe is 2c94af235ae600916d8aef1affe66d4d9098e8315f5aad5ea3f3283e67f9a582, and its MD5 is ae146f9406da1c387dc5f1f7be91605b. Two files with the same SHA-256 are identical, so use it to check you have exactly this file, not just one with the same name.
How up to date is this analysis of Yz7k7ivGt.exe?
This report reflects the scan on Oct 22, 2026. A file's fingerprint never changes, but antivirus engines keep learning, so a rating can change later. To get a newer result, scan the file again: we refresh the antivirus results when the saved ones are out of date.
