What is notification-centar[.]com?

notification-centar[.]com is virtually identical to windowsguidenews[.]com, robotornotcheckonline[.]club, reforeperc[.]pro, and many other websites. It redirects visitors to other rogue sites or displays dubious content.

Generally, people do not open notification-centar[.]com (or other websites of this kind) intentionally - browsers open them when potentially unwanted applications (PUAs) are installed. Typically, PUAs open dubious web pages, display advertisements, and collect data relating to browsing activity.

What is Peet?

Discovered by Michael Gillespie, Peet is malicious software that is classified as ransomware. This malware is a part of the Djvu ransomware family. Like most programs of this type, Peet is designed to encrypt victims' files and keep them inaccessible unless they are recovered with decryption software and a key.

To obtain these, victims are required to pay ransoms to cyber criminals (Peet's developers).

Furthermore, Peet adds the ".peet" extension to the filename of each encrypted file. For example, "1.jpg" becomes "1.jpg.peet". Instructions about how to decrypt files and pay the ransom are provided within the "_readme.txt" text file, which can be found in each folder that contains encrypted data.

What is BlackRat?

BlackRat is a remote access tool (RAT). Software of this type allows one computer to remotely access or control another computer.

RATs can be used legitimately, however, cyber criminals often employ them for malicious purposes. In such cases, these tools are known as remote access trojans. Being tricked into installation of BlackRat or other RATs can lead to serious problems. If this software was not installed intentionally, it should be uninstalled immediately.

What is yourfine2upgradeultimate[.]best?

yourfine2upgradeultimate[.]best is a deceptive site. When opened, it claims that the visitor's Adobe Flash Player is supposedly outdated and needs to be updated. The updates this website offer are bogus and designed to proliferate untrustworthy content (e.g. fake Mac cleaners/optimizers, browser hijackers, adware, etc.).

Typically, products endorsed on these scam web pages are fake and nonoperational. Most users access yourfine2upgradeultimate[.]best and other similar web pages unintentionally, since they are redirected by intrusive advertisements or Potentially Unwanted Applications (PUAs) already present on the device.

What is windowsguidenews[.]com?

When visitors arrive at windowsguidenews[.]com, it presents dubious content or opens a number of other untrustworthy websites. It functions like many other rogue websites such as, for example, reforeperc[.]pro, asonsbirthi[.]pro, and pushstack[.]co.

Most windowsguidenews[.]com visitors do not open this website address intentionally - they are redirected to it by potentially unwanted applications (PUAs) installed on their browsers or operating systems. Furthermore, PUAs are usually designed to display various advertisements and collect information relating to users' browsing habits.

What is Full System Care?

Full System Care is advertised as software that cleans, optimizes, and improves computer performance. In fact, this program is distributed through the download and/or installation set-ups of other programs. People often download and install software of this type unintentionally. Therefore, Full System Care is categorized as a potentially unwanted application (PUA).

What is "HARASSMENT COMPLAINT" email scam?

"HARASSMENT COMPLAINT" is an email scam designed to proliferate TrickBot trojan-type malicious software. This scam employs social engineering (scare tactics) to trick users into opening the attached file, consequently infecting the system with TrickBot. The user's personal details (such as name, workplace, etc.) are used in an attempt to give the impression of legitimacy.

The email is allegedly from the U.S. Equal Employment Opportunity Commission, claiming that the addressee (individual, to whom the letter is intended) is the subject in a filed sexual harassment complaint. Spam campaigns used to send scam/deceptive emails such as this often disguise the messages as "official", "important", and similar priority mail.

Note that they often contain spelling errors and other inconsistencies, which ease their identification as fraudulent mail. You are expressly advised against opening suspicious and/or irrelevant emails. Attachments and links found within them must never be opened, as they are the source of potential system infections.

What is robotornotcheckonline[.]club?

robotornotcheckonline[.]club is similar to many other rogue websites including, for example, pushstack[.]co, readmenewz[.]com, and rednews7[.]com. Visitors to these sites are all provided with dubious content or redirected to other untrustworthy websites.

Generally, they do not visit websites such as robotornotcheckonline[.]club intentionally - browsers open them due to installed potentially unwanted applications (PUAs). These apps are designed to gather information about people and feed them with intrusive ads.

What is reforeperc[.]pro?

reforeperc[.]pro is one of many rogue websites that, if visited, redirects visitors to other web pages of this kind or presents dubious content. Some examples of other websites similar to reforeperc[.]pro include asonsbirthi[.]pro, pushstack[.]co, and readmenewz[.]com.

Typically, browsers open these sites when potentially unwanted applications (PUAs) are installed on browsers and/or operating systems. I.e., people do not open them intentionally. Apps categorized as PUAs display advertisements and collect information relating to web browsing activity.

What is Mespinoza?

Discovered by GrujaRS, Mespinoza is malicious software that encrypts data and blocks access to it unless a ransom is paid. Programs of this type are classified as ransomware. Mespinoza adds the ".locked" extension to each encrypted file. For example, "1.jpg" becomes "1.jpg.locked", and so on. It also creates a ransom message within the "Readme.README" file.
