Virus and Spyware Removal Guides, uninstall instructions
What is Your Windows Licence has Expired?
"Your Windows Licence has Expired" is a fake error message that attempts to trick users into purchasing a valid activation key. It is distributed via various adware-type applications falsely claiming to provide a number of 'valuable functions'.
These applications usually infiltrate systems without users' consent. Furthermore, adware tracks Internet browsing activity and generates intrusive online advertisements.
What is find.mystart.space?
find.mystart.space is presented as a "top-notch" Internet search engine that significantly enhances the browsing experience by generating improved results. Judging on appearance alone, find.mystart.space barely differs from Google, Bing, Yahoo, and other legitimate search engines.
Therefore, many users believe that this site is also legitimate, however, developers promote it by employing rogue download/installation set-ups that hijack browsers and stealthily modify various options without permission. In addition, find.mystart.space often records information relating to users' Internet browsing activity.
What is Defray?
Defray is a ransomware-type virus discovered by malware security researchers from Proofpoint. Once infiltrated, Defray encrypts stored data using AES-256, RSA-2048, and SHA-2 cryptographies. Unlike other similar malware, Defray does not rename or append extensions to encrypted files.
Following successful encryption, the virus creates two text files: "HELP.txt" (placed on the desktop) and "FILES.txt" (placed in all existing folders). Both contain identical ransom-demand messages.
What is Search In Tabs?
Search In Tabs is a deceptive application that supposedly allows users to search the Internet directly from opened browsing tabs.
Judging on appearance alone, Search In Tabs may seem to be a legitimate and useful app, however, it is categorized as a potentially unwanted program (PUP) and adware. There are three main reasons for these negative associations: 1) installation without consent; 2) display of intrusive online advertisements; 3) potential tracking of users' Internet browsing activity.
What is safeforsearch.net?
According to the developers, safeforsearch.net is a legitimate Internet search engine that significantly enhances the browsing experience by generating improved results.
Initially, safeforsearch.net may appear legitimate and useful, however, this website is promoted using rogue download/installation set-ups designed to modify browser options without permission. Furthermore, safeforsearch.net gathers various information relating to users' Internet browsing activity.
What is CYRON?
Discovered by malware security researcher, Karsten Hahn, CYRON is a ransomware-type virus that stealthily infiltrates systems and encrypts various files. During encryption, it appends ".CYRON" to the name of each file (for example, "sample.jpg" is renamed to "sample.jpg.CYRON").
Following successful encryption, this virus opens a screen-locking pop-up window that blocks access to the desktop and contains a ransom-demand message. The screen-lock disappears after rebooting the system, however, at this point, all files will have been encrypted.
What is privacyassistant.net?
Similar to g-search.pro, privacyassistant.net is a fake Internet search engine that falsely claims to enhance the web browsing experience by generating improved results. Judging on appearance alone, this site barely differs from legitimate search engines such as Google, Bing, Yahoo, etc.
Therefore, many users believe that privacyassistant.net is also legitimate and useful, however, developers promote it via rogue downloaders/installers that modify browser options without permission. Furthermore, this site continually records various information relating to browsing activity.
What is Nuclear?
Discovered by Michael Gillespie, Nuclear is a new variant of a ransomware-type virus called BTCWare.
Once infiltrated, Nuclear encrypts various stored files and appends the ".[email].nuclear" extension to the name of associated filenames (for example, "sample.jpg" is renamed to "sample.jpg.[black.world@tuta.io].nuclear"). Following successful encryption, Nuclear opens a pop-up window containing a ransom-demand message.
What is shielddefense.net?
Shield Defense is a deceptive application that supposedly protects computers from various malware infections and blocks tracking of Internet browsing activity. Judging on appearance alone, Shield Defense may seem legitimate and useful, however, this app infiltrates systems without permission.
Furthermore, it stealthily modifies web browser settings and (despite the above claims) also monitor users' browsing activity. For these reasons, Shield Defense is categorized as a potentially unwanted program (PUP) and a browser hijacker.
What is You may have suspicious activity on your PC?
"You may have suspicious activity on your PC" is a fake error message displayed by a malicious website that users visit inadvertently - they are redirected by various potentially unwanted programs (PUPs) that infiltrate systems without permission (the "bundling" method).
As well as causing redirects, PUPs deliver intrusive online advertisements and continually record user-system information relating to browsing activity.
