“Your computer was locked – Error # DT00X2” popup removal

3 min read
Error # DT00X2 is an element of intimidation used in an ongoing tech support scam, where criminals try to charge victims for removing fake threats.

Tech support scams are dominating the landscape of non-email online frauds. The con artists behind them pass themselves off as Microsoft technicians and urge victims to give them a phone call, install dubious software or hand over sensitive credentials to enable troubleshooting otherwise the system will allegedly crash. The campaign involving “Your computer was locked – Error # DT00X2” error popups is this exact type. It is typically backed by malware that forcibly redirects a target user’s browser to a spoof web page designed according to the BSOD (Blue Screen of Death) theme. The whole hype appears credible due to the Microsoft-style design of the rogue site and the error code mentioned on it. No one who ends up on the page knows what on earth the Error # DT00X2 thing means, but quite a few people will at least get interested or even fall for the scare tactic.

What gives this scam a little bit more flavor of pressure is the additional popup alert that basically reiterates the warning in the background, stating the computer has been locked due to the above-mentioned error. The fake notification titled Security Warning blames it on “virus and spyware” that’s claimed to pose a threat to the user’s social media access credentials, financial details, as well as browsing-related data. To address the issue, the object of this manipulation is instructed to contact “Microsoft engineer” over a toll-free number, which varies for different sub-campaigns of the scam in question. According to the alert, the self-proclaimed engineer will walk the user through the recovery process by phone, and it’s purportedly obligatory to call them within 5 minutes or else the computer will go down the drain. Here’s the word-for-word rendering of this deceptive warning:

Error # DT00X2

Call Microsoft Technical Support at: [impostors’ phone number, e.g. +1-888-991-5705]

Do Not Ignore This Warning
If you close this page without resolving issue, access to your computer will be disabled to prevent further damage to our network.

Your computer has alerted us that it was infected with virus and spyware. The following data is at risk:

1. Facebook Login
2. Credit Card Information
3. Email Credentials
4. Browsing History and Data

You must contact us immediately so our engineers can guide you through the recovery process by phone. Please call us within the next 5 minutes to prevent complete loss of your computer.

Contact Microsoft Engineer: (Toll-Free): [rogue phone number]

Note how the swindlers cleverly emphasize that one of the reasons for blocking the computer is to thwart damage to Microsoft’s network that supposedly emanates from the victim’s malware-tainted PC. This way, the ne’er-do-wells pretend to pursue the commendable objective of protecting the user’s system while also saving the famous software giant the trouble of dealing with viruses that the computer is claimed to sprinkle around. By the way, the manipulative message in this particular scam is fairly well written from the grammar and spelling viewpoint, as opposed to the majority of similar tech support frauds out there. This suggests that the crooks are quite competent in what they are doing.

All attempts to close the Error # DT00X2 popup alert by clicking the X button or hitting OK are going to be futile as the script on the website will keep triggering it regardless. To add insult to injury, an additional popup will show up that asks the victim to enter their admin username and password – again, allegedly for troubleshooting. It goes without saying that typing anything in that dialog box is a really bad idea.

The key thing to bear in mind regarding the “Your computer was locked – Error # DT00X2” popup alert is that it’s fake. The only malicious code operating on your machine is the browser hijacker that’s causing constant redirects to the misleading web page in the first place. Therefore, you don’t have to call any phone number or, what’s worse, provide your admin access details. Just fix the browser redirect issue, which is a process that the steps below cover comprehensively.
