WinOptimizer is a dubious utility that carries out performance optimizations. It has a user-friendly interface accompanied by a set of effective tools to clean up your system. WinOptimizer claims that it can empty your system from irrelevant rubbish and other entries that overload your PC. Unfortunately, as Malwarebytes researchers determined, WinOptimizer creates a fake list of positives to allure users into buying extended versions of their software. By doing so, you will maintain your PC clean and stable. Note that WinOptimizer is not a virus, it is just one of the potentially unwanted programs that earn money on gullible people. Besides that, WinOptimizer supports web push notifications so that you could be informed about the latest news and products.

Crypren Ransomware is a type of malware that compromises your data by running encryption with the .ENCRYPTED extension. For instance, 1.mp4 or other regular files will be changed to 1.mp4.ENCRYPTED or similarly. Usually, due to asymmetric algorithms that are applied during encryption, the inflicted data becomes almost impossible to unlock. However, thanks to a security researcher named pekeinfo, there is no need in paying for decryption software. Besides that, we should point out that after the malware has finished the first step, it drops the READ_THIS_TO_DECRYPT.html file in each folder containing affected files. In this note, swindlers inform users about paid decryption service that requires buying a private key. Also, you are given 1 week to contact cybercriminals before your unique key will be destroyed. This key costs precisely 0.1 BTC (approximately 900 dollars). Luckily, you can download and use the decryption tool developed by pekeinfo in the article below. It turned out that Crypren Ransomware had a serious crack - they stored their keys locally.

Determined by Michael Gillespie (ransomware researcher), Mr.Dec Ransomware is a file-encrypting virus that makes money on desperate users who have their data locked. This virus exploits randomly-generated extension according to this pattern: [ID]victim's_ID[ID]. Extensions are meant to highlight encrypted files from normal ones. All files stored on your system including photos, videos, text documents, and other regular information, will be changed to 1.jpg[ID]gh839ag14hiol4ag[ID], for example. This makes your data impossible to open because of the generated gateway. After this, the ransomware drops a ransom note in the form of an HTML file (Decoding help.hta). In this message, you can see that extortionists prompt you to make a fast-pace decision on purchasing the decryption key. Otherwise, it will be destroyed and you will not be able to decrypt your data once the countdown is finished. To decode the compromised files, you should contact them via e-mail attached on top of the note. Most cybercriminals actively use cunning techniques to prompt users on buying the key by allowing them to send a couple of files for free decryption. Although it may seem like truth, you should never follow criminals' instructions unless you want to empty your pocket.

Developed by British company, SkyScanner is a legitimate application designed for Mac that analyzes flights, hotels and car hire databases to offer the cheapest and best deals from providers. Likewise other similar platforms, SkyScanner is very useful since it saves tons of time on searching for the tickets and combines them into a single application. However, SkyScanner is commonly distributed via malicious repacks that contain other potentially unwanted programs. Extortionists abuse its legitimacy to infect users with additional software like adware or browser hijackers without permission. This is why you should download SkyScanner and other legitimate software solely from official providers, especially if it is totally free. Unwanted applications can endanger your privacy and eat a lot of resources that slow down your PC. They are known to be altering browser settings in order to generate malicious redirects, ads, banners, fake pop-ups, and others. If clicked, all of this content can cause various infections like trojans, adware, browser hijackers and ransomware (which is the most dangerous) since it irreparably encrypts user's data.

Booking.com (can be also called Booking App or just Booking) is advertising application for Mac, that opens Booking.com website in program window on MacOS startup. Juging by appearance and behavior, this adware was not developed by the company, that operates self-titled website. Most likely, software was developed by third-party, that signed affiliation agreement with Booking.com and tries to earn affiliate comission spreading doubtful application with limited functionality. Window has weird name demo-app Title, the only task it performs is loading on startup and opening the homepage of Booking.com.

Seeing a title like Managed by your organization in your browser menu may raise up a lot of questions, especially about being infected with unwanted software. Of course, malware can hide its activity under "legitimate" covers like this, however, this specific feature is usually displayed because your browser is accessed by some organization. This can happen due to third-parties installations like Antivirus that set own enterprise policy for Google Chrome browser. Sometimes, you can log in to certain websites that are allowed to do these changes as well. Either way, if you are getting pissed off due to this entry, then we will help you get rid of it in the article below.

Xorist-EnCiPhErEd shed some light on the ransomware world a couple of years ago and still targets users until these days. Being part of the Xorist family, it encrypts data by using XOR or TEA algorithms and assigning .EnCiPhErEd extension to all files. For instance, 1.mp4 will suffer the change to 1.mp4.EnCiPhErEd. If you try to open any of the infected files, you will see a pop-up error window that displays ransom information. Unlike other ransomware, its developers ask victims to send an SMS message to the mentioned number. Besides that, the virus drops a text file called HOW TO DECRYPT FILES.txt which is identical to the pop-up window. If you fail to enter the code within 5 attempts, your files will be deleted completely, as extortionists claim. Once done, you will more likely get a browser-based link to pay for the decryption software. However, there is no need to meet ransom demands because Fabian Wosar of Emsisoft has found a way to decrypt files encrypted by Xorist.

Locky is a ransomware virus that encrypts you files using the RSA-2048 and AES-1024 algorithms and demands 0.5 BTC (bitcoins) (equivalent to $207) for receiving "Locky Decrypter" to allow user decrypt his documents and images. This is a very dangerous blackmailing virus and there are currently only a few ways to decrypt your files. In this guide, we collected all information available that can help you remove Locky ransomware virus and restore infected files.
