Remove Hello4 and Blank Window2 (Uninstall Guide)

If you keep getting random blank windows named Hello4 when you turn off your PC and Blank Window2 when you start your computer, then you're infected with malware. Malware that causes these blank windows to show up may also hijack your web browser and redirect you to spam/malicious websites. What is more, it may download and install additional malware onto your computer, most likely TDL rootkit, Vundo trojan or Zbot spyware. While the blank Hello4 and Blank Window2 pop-ups may look more like software errors they are actually clear signs of malware infection. So, how to do you remove Hello4/Blank Window2 malware? First of all, you should scan your computer with several free anti-rookit utilities to check whether your computer is infected with a rootkit or not. Then you should scan your computer with multiple anti-malware programs. We recommend Malwarebytes Anti-Malware and Hitman Pro, however, you can use any other. Also, we do not recommend removing malware manually because you can accidentally remove safe files, especially when there are several randomly named malicious files associated with this infection. If you can't run malware removal tools properly, reboot your computer in safe mode/safe mode with networking. For more information, please follow the steps in the removal guide below.
