How dangerous is the Powered by Corona Borealis Virus and how to recognize it?

The virus is quite dangerous. It appears in the form of advertisements, which is its famous camouflage. Yes, there are so many ads out there in the cyberspace that it is hard to review them all and confusing to figure out which ones are real and which ones are not. BUT if you see excessive amount of pop-up ads, flashing text boxes, banners that show and quickly hide, and these can’t seem to stop, then you should know that this is a sign of Powered by Corona Borealis Virus.

When your PC becomes infected with the malware you will quickly notice major slowness in its functioning. It could take hours for it to start, reboot or it may just get stucked and kind of freeze. This will all be accompanied by glitches and all kinds of bugs. Just imagine a person struggling with a couple viruses, well it will be the same situation with your computer.

Also, if you look for files at their usual place where you’ve stored them, but you find the folders empty (that given that no one else uses your computer account but you only) or the files dislocated, or containing any other information, BUT the one you saved on first place, then you should take some emergency measures to uninstall the virus.

Sometimes this may require a click, but not always. They could treat your most precious data for identity theft purposes, laundering of money, illegal oversea wiring transfers, just to mention a few of their goals.

How did the Powered by Corona Borealis Virus get installed on your PC?

There are as many sure ways as there are many hypothesis. Some of the tested and experienced methods include (this is not an all inclusive list):

  1. Software Bundling: you attempt to download a certain file, but you don’t notice the additional files attached to it. These are usually infected and spread the disease into your system quickly.
  2. Spam e-mail messages from advertising companies.
  3. Phishing e-mails: fake e-mails pretending to be sent by your friends.
  4. Clicking on some or even one of the pop-up ads mentioned above
  5. Through a social media account of one of your friends that has been hacked

There are many ways the malware could be spread, but the steps for removing it are the same: uninstalling, rebooting and scanning every single file you download from now on.
