Virus and Spyware Removal Guides, uninstall instructions

What is MacKeeper?

Developed by Zeobit and then acquired by Kromtech, MacKeeper is a legitimate and useful application for Mac users. It provides functionality that allows users to optimize and increase system performance.

Despite this, some MacKeeper affiliates employ dubious/unacceptable measures to proliferate this software. Therefore, it can be classed as potentially unwanted program (PUP).

What is Payerranso?

First discovered by Leo, Payerranso is a ransomware-type virus developed using Microsoft's .Net Framework. Immediately after infiltration, Payerranso encrypts most stored data and appends filenames with the ".payerranso" extension (for example, when encrypted "sample.jpg" becomes "sample.jpg.payerranso").

Once files are encrypted, it is impossible to use them. Furthermore, Payerranso changes the desktop wallpaper and creates a text file ("Message_Important.txt"), placing a copy in every existing folder.

What is billmscurlrev.com?

billmscurlrev.com is a rogue site identical to celeryleek.com, thesterminator.com, questionfly.com, popunderzone.com, and many others. This site redirects to other random websites. Furthermore, users often visit billmscurlrev.com inadvertently - they are redirected by potentially unwanted programs (PUPs) that infiltrate systems without consent.

Research shows that, as well as causing redirects, PUPs deliver intrusive ads, gather sensitive information, and misuse system resources to run unwanted processes.

What is LOCKME?

LOCKME is a ransomware-type virus discovered by Michael Gillespie. Immediately after infiltration, LOCKME encrypts most stored files and appends filenames with the ".lockme" extension (e.g., "sample.jpg" becomes "sample.jpg.lockme"). Henceforth, using files become impossible.

Once the files are encrypted, LOCKME generates a text file ("README_FOR_DECRYPT_YOUR_FILES.txt") and places a copy in every existing folder.

What is chromesearch.online?

Identical to chromesearch.info, chromesearch.win, chromesearch.today, and many others, chromesearch.online is a fake Internet search engine that, according to developers, significantly enhances the browsing experience by generating improved results.

Judging on appearance alone, chromesearch.online may seem similar to Bing, Yahoo, Google, and other legitimate search engines. For this reason, many users believe that chromesearch.online is also legitimate.

In fact, developers promote this site via browser-hijacking download/installation set-ups. Furthermore, it continually records information relating to users' Internet browsing habits.

What is AAC?

First discovered by CyberSecurity, AAC is ransomware-type malware that stealthily infiltrates the system and encrypts most stored data. Immediately after infiltration, files become unusable. In addition, AAC adds the ".aac" extension to the name of each compromised file.

For instance, "sample.jpg" becomes "sample.jpg.aac". Following successful encryption, AAC creates a text file ("Learn how to recover your files.txt") and places a copy in each existing folder.

What kind of scam is "Congratulations, You Have Won"?

"Congratulations, You Have Won" is a scam pop-up displayed by a rogue website. Research shows that users often visit this website inadvertently - they are redirected by various potentially unwanted programs (PUPs) that typically infiltrate systems without users' consent.

In addition to causing redirects, potentially unwanted unwanted programs generate intrusive ads (banners, coupons, pop-ups, and so on), collect sensitive data, and (in some cases) misuse system resources to run unnecessary processes.

What kind of scam is CRITICAL ALERT FROM MICROSOFT?

"CRITICAL ALERT TO MICROSOFT" is a fake error message displayed by a deceptive website to which users are redirected by various shady pages, ads, or unwanted programs. Research shows that these programs usually infiltrate systems without consent.

In addition to causing redirects, apps of this type diminish system performance, generate 'malvertising' ads (pop-ups, coupons, banners, etc.), and record various user-system information.

What is JSMiner-C?

First detected by Avast, JSMiner-C is malware that helps developers to mine cryptocurrency. JSMiner-C is essentially designed to cause redirects to malicious sites that mine Monero cryptocurrency.

These sites are not limited to mining cryptocurrency - they also proliferate potentially unwanted adware-type programs (PUPs), deliver intrusive advertisements, and collect various sensitive data.

What is MindLost?

Discovered by MalwareHunterTeam, MindLost is a ransomware-type virus that infiltrates the system and encrypts a portion of stored data. Note that Microsoft detects this malware under another name - Paggalangrypt. During encryption, MindLost appends filenames with the ".enc" extension (e.g., "sample.jpg" is renamed to "sample.jpg.enc").

From this point, using compromised files becomes impossible. Immediately after encryption, MindLost downloads an image file from the Internet and sets it as the desktop background.
