Known Coronaborealis Ads Deceptions

This specific type of malicious software is notorious for the many tricks and deceptions it is going to employ in order to make you install additional virus applications. This is a thing we always try to put an emphasis on. The way for the malware to really harm your device is possible only if you let it gain the required access to do so. We are far from thinking that any sane person would do so willingly, so the other way is through being tricked. We are going to list some of the typical ways in which this and other similar types of adware might try to dupe you, as well as some general recommendations.

  • Different types of warning pop-ups might appear while you are browsing. One such warning message pop-up might imply that you are infected with a computer virus and need to download a specific “fix” to deal with this. Needless to say this is just a ploy to make you install more malware and not a real anti-virus tool.
  • A different pop-up might say you have missing updates for well-known programs like Windows Media Player, Java, Adobe or something else that you might be interested in updating. Of course you should do not such thing, these are just more virus applications waiting to flood your hard drive.
  • Another possible trick is a similar notification about required or essential Windows updates missing from your system. Never download Windows or program updates from unconfirmed sources, you are more than likely going to end up with a program like Coronaborealis Ads or even worse.
