BV:Miner-T. How to remove? (Uninstall guide)
BV:Miner-T is a dangerous cryptojacker that abuses victims' operating systems to illegally mine crypto
BV:Miner-T is a cryptominer that illegally mines digital coins from victims
BV:Miner-T is a cryptojacker[1] that works similarly to JS:Miner-c – a malicious code embedded directly into malicious or hacked sites runs a script which allows bad actors to monetize on digital currency mining. Mining crypto is an entirely legitimate process, and many website authors prefer this method over serving ads. Additionally, users don't usually mind to share some of their CPU power in order to avoid annoying pop-ups. However, this process becomes highly illegal if the user is not informed about the process. BV Miner T is a name used by several security applications which prevent users from entering corrupted sites that illegally mine crypto like Bitcoin, Monero, Litecoin, etc.

Cryptocurrency miners have been on the rise, and some of the ransomware authors even shifted their business model. Best example would be XiaoBa ransomware, which switched from Chinese-only targeting malware to global ransomware that utilized crypto mining capabilities.[2]
However,cryptojackers are different. It is not an infection per se, but rather a script that runs on a compromised website, making BV:Miner-T removal as easy as closing down the site. Nevertheless, it is vital to scan your machine if your anti-virus is detecting any type of malware. In case something is found, you should make use of computer repair software like Reimage to bring it back to normal functionality. You can also do all repair work yourself if you are computer-savvy, but it is not recommended to those who do not have much practice with computing.
The only way to remove BV:Miner-T activity is to close down your browser, and never revisit the site. Note that the cryptominer can be activated on any browser, including Google Chrome, Internet Explorer, Mozilla Firefox, Safari, and many others.
There are two ways cybercrooks can make BV Miner T crpytomining successful: they either inject the script into a poorly protected website (even if it is legitimate) or create their own. The first option is more popular, as there is no need to direct traffic. Researchers observed that cybercriminals make use of outdated versions of Drupal software so take over legitimate websites with malicious JavaScript.[3]
It would be incorrect to call the threat BV:Miner-T virus, as it does not make any changes to the system. Therefore, as long as you use powerful anti-malware software and keep it up to date, you can remove BV:Miner-T activity from your machine without much trouble.

Do not let crooks monetize on a behalf of your computer power
In case you do not use security software (which is terrible cybersecurity negligence), or you never encountered such threats as BV:Miner-T, look out for these symptoms:
- Increased CPU/GPU activity
- Fans spinning on full power
- Overall slowdown of the machine
- Installed software crashing
- Malfunction of the installed software
- Frequent errors or/and BSoDs
If you notice any of these, download and install anti-malware software and perform a full system scan immediately. After that, make sure you keep the security application running at all times and update it regularly.
Besides using reputable anti-malware tools, it is also advisable to avoid suspicious websites. Many coinminers are hidden in such sites like torrent, file-sharing, porn, gambling, online dating, and similar. Crooks know that millions use these type of domains, so utilizing their CPU brings them the maximum amount of profits in Bitcoin, Monero, Ethereum, etc. In the meantime, victims suffer from compromised computer usage, high electricity bills and hardware wear out.

Beware that even the most trusted websites can be mining digital money without their owners' knowledge. Thus, just because the security certificate is valid, does not mean that the site is entirely safe.
