CoinMiner is considered to be a virus, a type of malware that is designed to create havoc in the computer. A CoinMiner infection can be as harmless as showing annoying messages on your screen or as vicious as disabling the computer altogether. Regardless of the virus' behavior, the primary objective of computer hackers who program viruses such as CoinMiner is to delete, destroy or steal data.
CoinMiner are software programs that infect the computer to disrupt its normal functioning without the computer user’s knowledge. Typically, a virus gains entry on the computer as an isolated piece of executable code or by through bundling/piggybacking with other software programs.
Once the CoinMiner gains entry into the computer thru downloads from questionable websites, infected email attachments, external media such as pen drive, DVD, and memory card already infected with CoinMiner, fake updates that trick in installing and infected documents circulating on peer-to-peer (P2P) file sharing networks and torrent sites.
The symptoms of infection can vary depending on the type of virus. Some viruses can keep adding shortcuts of other programs on the desktop, while others can start running unwanted programs, also referred as “PUP” (Potentially Unwanted Programs) to intentionally slow down the computer.
There are also more harmful viruses that present the infamous “blue screen of death”, a critical system error that forces you to keep restarting your computer. Viruses like CoinMiner can even delete the important files and folders.
The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Therefore, carefully analyze each window of the download/installation dialogs and opt-out of all additionally-included programs. We also strongly recommend that you download your software from official sources only and, preferably, using a direct download links. Intrusive ads often look legitimate, however, they redirect to dubious websites (gambling, pornography, etc.) If you experience these redirects, uninstall all suspicious programs/browser add-ons.
All PNP personnel as well as the public are advised to follow the tips in order to avoid the risk of CoinMiner Virus, to wit:
- Always update the anti-virus software installed in your computer and conduct regular full scanning at least once a week;
- Enable pop-up blocker;
- Remove malicious add-ons from Internet Explorer, plug-ins from Google Chrome and rogue extensions from Mozilla Firefox;
