How do I get rid of blaster worms?

That is a tricky worm to eliminate, but there are many ways in which to remove the Blaster Worm. I suggest downloading Malwarebytes from Google and booting your computer into safe mode with networking if the worm prevents you from accessing the internet etc in normal mode. To boot your computer in safe mode, press f8 continuously and select safe mode or safe mode with networking. Run a scan to remove the worms. If there is an issue that prevents you from installing the software, I suggest running a clean computer, download Malwarebytes and put it onto a USB and then transfer it over to the infected computer. Another safety precaution would be to download SuperAntiSpyware or a free Antivirus so your computer will not get infected in the near future. Also observe the sites you visit or the email attachments you open to prevent future virus and worm attacks.
