What is Windows Operating System Alert?

"Windows Operating System Alert" is a fake error message similar to Found 4 Virus, Error DT00X2, ERROR 268d3x8938, and many others. It is delivered by various dubious websites. In most cases, users visit these sites inadvertently - they are redirected by potentially unwanted applications (PUAs) or advertisements displayed on other rogue sites.

Be aware that many potentially unwanted applications infiltrate systems without permission and, as well as causing redirects, deliver intrusive advertisements and gather sensitive information.

What is offerzone.click?

Similar or identical to wpformb.com, shalledinition.club, click-on-this-now.online and many more, offerzone.click is a rogue website that, once visited, causes redirects to other untrustworthy sites. Most users arrive at offerzone.click unintentionally - they are redirected by potentially unwanted programs (PUPs).

These redirects can also be caused by intrusive ads. PUPs usually infiltrate systems without users' consent and, in addition to unwanted redirects, deliver various intrusive ads and collect personal data.

What is igkxr.biz?

igkxr.biz is one of many rogue websites available. Some examples of identical (or very similar) websites include click.new-posts.support, adxfactory.com, and yourmobile2018.com. This website triggers redirects to various other untrustworthy/potentially malicious sites.

Most users visit igkxr.biz inadvertently - they are redirected by potentially unwanted programs (PUPs) that are usually installed inadvertently or without permission. In addition to unwanted redirects, PUPs gather user-system information, deliver intrusive ads and, in some cases, misuse system resources.

What is flurryad.com?

flurryad.com is a rogue website virtually identical (or very similar) to click.new-posts.support, adxfactory.com click-now-on-this.online, and many more.

This website redirects visitors to other untrustworthy and potentially malicious sites. In most cases, users visit flurryad.com inadvertently - potentially unwanted programs (PUPs) or intrusive ads cause redirects to it. As a rule, PUPs infiltrate systems without users' consent, cause unwanted redirects, deliver various intrusive advertisements, and collect user information.

What is Trojan.win32.adject.gen?

Trojan.win32.adject.gen is deceptive malware that infiltrates the system and modifies the content of visited websites. Note that, unlike adware-type applications (which have similar behavior), Trojan.win32.adject.gen cannot be seen in the list of installed applications, browser extensions, etc.

Therefore, distinguishing and eliminating this threat is more difficult as compared to regular adware.

What is PublicHotspot?

PublicHotspot is a deceptive application that typically infiltrates systems without users' consent - developers distribute it using a deceptive marketing method called "bundling". After system infiltration, PublicHotspot delivers intrusive advertisements and gathers sensitive information. For these reasons, it is categorized as adware and a potentially unwanted application (PUA).

What is PC CleanUp 2018?

PC CleanUp 2018 is a dubious application that claims to remove computer infections and optimize the system.

Judging on appearance alone, PC CleanUp 2018 may seem legitimate and useful, however, it often infiltrates systems without permission (developers distribute it using the "bundling" method). Therefore, PC CleanUp 2018 is categorized as a potentially unwanted application (PUA).

What is CryptoJoker?

CryptoJoker is a ransomware-type virus that encrypts various files (for example, .txt, .doc, .docx, .ppt, etc.) stored on victims' computers.

All files are encrypted using AES-256 encryption, and once successfully encrypted, victims are presented with a message stating that they are required to pay a ransom in bitcoins (otherwise the files will remain permanently decrypted). CryptoJoker is distributed as a .PDF file and, therefore, is often proliferated as an email attachment.

What is ExecutionerPlus?

Recently discovered by MalwareHunterTeam, ExecutionerPlus is a ransomware-type virus based on CryptoJoker. Once infiltrated, ExecutionerPlus encrypts most stored data and appends the "pluss.executioner" or ".destroy.executioner" extension to the name of each file.

For example, "sample.jpg" is renamed to "sample.jpgpluss.executioner" or "sample.jpg.destroy.executioner". Immediately after encryption, ExecutionerPlus places an HTML file ("Readme.html") on the desktop. Note that this malware is still in development and, thus, might contain bugs.

What kind of malware is BlueEagle?

BlueEagle is a ransomware-type virus discovered by malware security researcher, Michael Gillespie. Once infiltrated, BlueEagle encrypts various files and appends the filenames with the ".SaherBlueEagleRansomware" extension.

For instance, "sample.jpg" is renamed to "sample.jpg.SaherBlueEagleRansomware". BlueEagle then opens a pop-up window and changes the desktop wallpaper.
