Virus and Spyware Removal Guides, uninstall instructions

What is RETIS?

Discovered by malware security researcher, SDK, RETIS is a ransomware-type virus that stealthily infiltrates the system. Immediately after infiltration, RETIS encrypts most stored data and appends filenames with the ".crypted" extension (for instance, "sample.jpg" is renamed to "sample.jpg.crypted"). Once files are encrypted, RETIS changes the desktop wallpaper.

What is lamclick.com?

Identical to coolproductreview.com, pushedwebnews.com, cld-secure.com, and many others, lamclick.com is a rogue website designed to redirect to various other dubious websites. Users are often redirected to lamclick.com by potentially unwanted programs (PUPs).

These apps typically infiltrate systems without permission. Furthermore, PUPs often generate intrusive ads (pop-ups, banners, coupons, etc.), gather sensitive data, and misuse system resources.

What is gamesquest.co?

GamesQuest is a rogue application that supposedly allows users to search for games online. Judging on appearance alone, this application may seem legitimate, however, GamesQuest is categorized as a browser hijacker and a potentially unwanted program (PUP).

There are three main reasons for these negative associations: 1) stealth installation without users' consent; 2) modification of web browser settings, and; 3) information tracking.

What is SIGMA?

SIGMA is a ransomware-type virus discovered by malware security researcher, Michael Gillespie. This high-risk malware is distributed using spam emails that contain a message stating that users will be charged $3000+ from their MasterCard, unless they open a MS Office document attached.

After opening this attachment and entering the password provided, users will inadvertently execute configured macros, which will then immediately perform a number of actions to download and run SIGMA ransomware.

Once infiltrated, this virus encrypts stored data using RSA-2048 cryptography and appends four random letters/digits to the name of each encrypted file (e.g., "sample.jpg" might be renamed to a filename such as "sample.jpg.Ka8E"). Immediately after encryption, SIGMA changes the desktop wallpaper and places two files ("ReadMe.html" and "ReadMe.txt") on the desktop.

What is perlintab.com?

Identical to Equal Tab, Solo-Bar, 3Spiral Wave, and many others, Perlin Tab is a rogue application that supposedly allows users to customize their homepage.

On initial inspection, Perlin Tab may seem legitimate and useful, however, it typically infiltrates systems without users' consent. Furthermore, it promotes a fake Internet search engine and records user-system information. For these reasons, Perlin Tab is categorized as a potentially unwanted program (PUP) and a browser hijacker. 

What is Cydoor Spyware?

"Cydoor Spyware" is another fake error displayed by a malicious website. Research shows that users are often redirected to this site by various potentially unwanted programs (PUPs) that infiltrate systems without permission.

In addition to redirects, PUPs deliver various intrusive advertisements (coupons, pop-ups, banners, etc.), reduce overall system performance, and continually gather sensitive data.

What is coolproductreview.com?

coolproductreview.com is a rogue website identical to bestadbid.com, popads.net, cld-secure.com, and many others. It causes redirects to various dubious websites.

In addition, users often visit coolproductreview.com inadvertently - they are redirected by potentially unwanted programs (PUPs) that infiltrate systems without users’ permission. As well as causing redirects, PUPs deliver intrusive advertisements, gather information, and (in some cases) run unnecessary background processes.

What is equaltab.biz?

Equal Tab is a rogue application identical to 3Spiral Wave, Photorito, Solo-Bar, and many others. 

By offering functionality that allows users to customize their homepages, Equal Tab attempts to give the impression of legitimacy, however, this potentially unwanted program (PUP) infiltrates systems without permission and collects various information (mostly relating to web browsing habits).

Furthermore, Equal Tab is categorized as a browser hijacker - a form of software that modifies browser settings without users' consent.

What is solo-bar.net?

Solo-Bar is a rogue application that supposedly allows users to change the appearance of their homepages.

Although Solo-Bar may seem legitimate, be aware that it is categorized as a potentially unwanted program (PUP) and a browser hijacker. There are three main reasons for these negative associations: 1) stealth installation without users' consent; 2) modification of Internet browser options, and; 3) information tracking.

What is Cyclone?

Discovered by malware security researcher, Karsten Hahn, Cyclone is a ransomware-type virus that stealthily infiltrates the system and encrypts most stored data with AES-256 cryptography. During encryption, this malware appends filenames with the ".Cyclone" extension.

For example, "sample.jpg" is renamed to "sample.jpg.Cyclone". Once files are encrypted, they become unusable. Immediately after encryption, Cyclone opens a pop-up window and places a "key.txt" file in every existing folder.
