What is PC Support Center?

PC Support Center is a deceptive app identical to HotShoppy, CoolShopper, Myshopcoupon, and many others. By offering a feature to enhance system performance, PC Support Center attempts to give the impression of legitimacy. In fact, it is categorized as a potentially unwanted application (PUA) and adware.

There are three main reasons for these negative associations: 1) stealth installation without users' consent; 2) display of intrusive ads, and; 3) tracking of web browsing activity.

What is search.pensirot.com?

Identical to search.mogobiggy.com, search.pikatika.com, search.worthut.com, and many others, search.pensirot.com is a fake Internet search engine that falsely claims to enhance the browsing experience. 

Judging on appearance alone, search.pensirot.com may seem legitimate and useful, however, this site is promoted using rogue download/installation set-ups (browser hijackers) that modify browser options without permission. In addition, search.pensirot.com stealthily records various information (mostly relating to users' Internet browsing activity).

What is GANDCRAB 5.0.4?

GANDCRAB 5.0.4 is another variant of high-risk ransomware called GandCrab designed to infiltrate systems and encrypt most stored files. As with most ransomware, a random appendix is added to the name of each compromised file. In this case, GANDCRAB 5.0.4 adds the ".rotxkry" string (e.g., "sample.jpg" is renamed to "sample.jpg.rotxkry").

Once encrypted, data instantly becomes unusable. Note that encryption is not the only feature of GANDCRAB 5.0.4 ransomware. This virus is also designed to change the desktop wallpaper and place a text file ("[random-string]-DECRYPT.txt") and a photo of Valery Sinyaev in every existing folder.

What is additionalsearch.co.uk?

additionalsearch.co.uk is a fake search engine that supposedly enhances the browsing experience by generating improved results and providing the latest world news. Judging on appearance alone, this site barely differs from Google, Bing, Yahoo, and other legitimate search engines.

Therefore, many users believe that additionalsearch.co.uk is also legitimate, however, it is promoted using browser-hijacking downloaders/installers that modify  browser options without permission. Furthermore, this site continually gathers information relating to browsing activity.
