Scammers are tricking victims into paying $25 for fake security software, ZDNet reports .
The tech-support scammers use fake blue screen of death (BSOD) messages and a phony "Troubleshooter for Windows" application to try to sell a supposed Microsoft security product called "Windows Defender Essentials." The name sounds like two real Windows anti-malware applications: Windows Defender and Security Essentials.
Malwarebytes researcher Pieter Arntz says the Troubleshooter app is being distributed through a cracked software installer.
Instead of troubleshooting, the app says that "Windows has encountered an unexpected error" and the computer is "missing .dll registry files resulting in computer failure." Victims are encouraged to click "next" to diagnose and troubleshoot the issue.
Once the victim does that, they're led to a screen that lists false problems and which says the troubleshoot couldn't fix the issue, but it can be resolved by clicking a "Recommended" link to "Buy Windows Defender Essentials." Selecting this leads to a page that encourages victims to send $25 to the scammer's PayPal account.
A browser-based screen locker goes away after the money is paid.
According to BleepingComputer, victims can "trick" the program into shutting down: once they reach the PayPal purchase screen, they can hit Ctrl+O to open a dialogue box, and then enter http://hitechnovation.com/thankyou.txt. This makes the program think they've paid the $25, and it shuts down.
