Strong evidence · Two or more major antivirus engines agree.

Don't run it: it is unwanted software

If you already ran it, uninstall it and anything that came with it.

What to do now4 steps

This is unwanted software (adware or a bundled program), not an infection. Remove it and undo any changes it made.

If you haven't installed it

  1. Don't run this file. Delete it, then empty the Recycle Bin.

If you already ran it

  1. Uninstall it and any program you don't recognise that arrived at the same time (Settings > Apps on Windows).

  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.

The reasoning behind this verdict

Analyst conclusion

The strongest evidence points to an OfferCore bundle installer or downloader: 22 of the 71 antivirus engines that checked it flagged it, including seven major antivirus engines. Its valid Infivora signature offers little reassurance because all 10 previously observed samples from that signer were harmful, while the clean sandbox run remains meaningful but insufficient counter-evidence.

Where this verdict could be wrong5 caveats
  • One completed sandbox run returned clean, so the test run did not independently confirm malware behavior.
  • The two inspected contacted hosts had no known-malicious or known-suspicious cache matches, although host reputation can change and does not negate the engine findings.
  • The executable has a valid Infivora signature, but that publisher's observed history consists of 10 malicious samples and no safe samples.
  • No malware-specific YARAify or MalwareBazaar match was found.
  • Several engines describe the payload as a potentially unwanted application or bundle installer rather than a conventional trojan.

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: 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 PKTiXKEVz.exe a virus?
PKTiXKEVz.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. 22 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 PKTiXKEVz.exe?
PKTiXKEVz.exe is a Windows program, about 16.2 MB. It carries no version information saying what it is or who made it. VirusTotal first saw it on Oct 13, 2026.
How many antivirus engines detected PKTiXKEVz.exe?
22 of the 71 antivirus engines that checked it flag PKTiXKEVz.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 PKTiXKEVz.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 PKTiXKEVz.exe?
To remove PKTiXKEVz.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 PKTiXKEVz.exe?
Antivirus engines classify PKTiXKEVz.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 PKTiXKEVz.exe digitally signed?
Yes. PKTiXKEVz.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 PKTiXKEVz.exe?
The SHA-256 fingerprint of PKTiXKEVz.exe is d459ac05e5709c36eca4eb5442a30650844eaf69f13cccf33a67ad37ffbcc9f3, and its MD5 is 935d8bc035efbb5eb8c213c57731ccd7. 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 PKTiXKEVz.exe?
This report reflects the scan on Oct 13, 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.
