How to remove Weknow.start.me (Mac)

Standard

Weknow.start.me is unsafe search engine, related to Weknow company, that is notorious for its Weknow.ac hijacker. Hijacker can modify search engine and homepage settings in Safari, Google Chrome and Mozilla Firefox on Mac. This one is built on another platform (start.me) and redirects user’s queries to find.coinup.org. After some investigation, it turns out, that coinup.org is a platform, that allows search providers earn money on using user’s computer power by mining cryptocurrency. So, after Weknow.start.me installs in browsers, it may use special JavaScripts or install certain browser extensions (like CoinUp add-on) to mine crypto-coins.

How to remove Dharma-Frend Ransomware and decrypt .frend files

Standard

Dharma-Frend Ransomware is typical embranchment of Crysis-Dharma-Cezar ransomware virus family. This particular variation appends .frend extension to encrypted files and makes them unusable. Dharma-Frend Ransomware doesn’t have effective decryptor, however, we recommend you to try instructions below to attempt restoring your files. Dharma-Frend Ransomware adds suffix, that consists of multiple parts, such as: unique user’s id, developer’s e-mail address and .frend suffix. The pattern of filename after encryption looks like this: file called 1.doc will be converted to 1.doc.id-{8-digit-id}.[{email-address}].frend. Authors of Dharma-Frend Ransomware extort $10000 ransom from the victims. Using cryptocurrency and TOR-hosted payment websites makes it impossible to track malefactors. Besides, victims of such viruses often get scammed, and malefactors don’t send any keys even after paying the ransom. Unfortunately, manual or automatic decryption is impossible unless ransomware was developed with mistakes or had certain execution errors, flaws or vulnerabilities. We do not recommend to pay any money to malefactors. Often, after some period of time security specialists from antivirus companies or individual researchers decode the algorithms and release decryption keys.

How to remove Dharma-Amber Ransomware and decrypt .amber files

Standard

Dharma-Amber Ransomware is nearly identical to previous versions of Crysis-Dharma-Cezar ransomware family, except that now it adds .amber extension to encrypted files. Dharma-Amber Ransomware constructs file extension from several parts: e-mail address, unique 8-digit identification number (randomly generated) and .amber extension. ID number is also used for victim identification, when hackers send decryption key (although they do it rarely). Dharma-Amber Ransomware authors demand from $500 to $15000 ransom, that can be paid in Monero, Dash or BTC (BitCoins), and in return they promise to send decryption key. This type of ransomware is coded and distributed as RaaS (Ransomware as service), and people your are trying to contact can be just resellers. That is why, amount of money they want for decryption can be very big. Using cryptocurrency makes it impossible to track the payee. We do not recommend to pay any money to malefactors. Usually, after some period of time security specialists from antivirus companies or individual researchers break the algorithms and release decryption keys.
