Remove BV:Miner-T (Recovery Instructions Included) - Jan 2021 update
BV:Miner-T is a dangerous crypto-mining virus that abuses victims' devices to gain profit
BV:Miner-T is the threat that targets inadequately secured websites and implements cryptocurrency mining by injecting malicious scripts. Various vulnerabilities and outdated versions of programs give the opportunity for hackers to abuse such sites via the Javascript library. The particular term is used by AV engines when malicious activity is detected. The pop-up indicates the connection of the particular site to miner/trojan, so you can take action as soon as possible.
Users online report this often-occurring message with various concerns including the suspicions about particular websites involved and BV:Miner-T scripts.[1] In most cases, there are no issues with the website, and those are legitimate, but your machine may end up used to mine currency without permission if you don't react as soon as possible.
Constant malware indications and notices about virus activity should push you to run a proper scan on the machine with a reputable anti-malware tool. This is how you can get rid of the issues and possible other malware entirely. If BV:Miner-T virus already runs on the PC, it can be removed this way too.

BV:Miner-T is a cryptojacker[2] 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 of 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 that 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. The best example would be XiaoBa ransomware, which switched from Chinese-only targeting malware to global ransomware that utilized crypto mining capabilities.[3]
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 ReimageIntego 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. BV:Miner-T is a script that is embedded into hacked or malicious websites that helps cybercrooks to monetize on visitor's computer power 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 cyber crooks 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.[4]
This miner does not make any changes to the system but can damage files and affect the performance this way. 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 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
- The 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.
Online malware spreads around via insecure sites and deceptive pop-ups
Many coinminers are hidden in such sites like torrent and pirated software distributing pages, file-sharing, porn, gambling, online dating, and similar content. Crooks know that millions use these types 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.
You should also pay attention to pop-ups, ads, and promotional content that comes to your screen out of nowhere. Clicking on shady commercial content can install toolbars or in-browser material to distract you when the additional trojan script gets loaded on the machine.
Those virus notices are no joke, so you should run your anti-malware tools more often to keep the machine safe and virus-free and cut before the issue appears on the AV report for you.
Stop BV:Miner-T virus activities by cleaning the PC fully
As we already mentioned, the easiest way to remove BV:Miner-T and stop all the suspicious activities is to exit the compromised website and never return to it again. 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.
BV:Miner-T removal from your browser can be a success at all times if you use anti-malware software that can detect and block the threat. Beware that, in case the security program was not installed, and you visited several dodgy websites, malware could have slipped into your machine.
Trojans, keyloggers, worms, and such might not give out any symptoms at all and perform malicious actions without users ever noticing. Below you will find instructions on how to deal with an infection of such kind. However, you should benefit from a scan using a repair tool ReimageIntego and security software like SpyHunter 5Combo Cleaner or Malwarebytes. Any BV Miner T virus damage can affect your time on the computer significantly, so make sure to clean all the traces.

Choose a proper web browser and improve your safety with a VPN tool
Online spying has got momentum in recent years and people are getting more and more interested in how to protect their privacy online. One of the basic means to add a layer of security – choose the most private and secure web browser. Although web browsers can't grant full privacy protection and security, some of them are much better at sandboxing, HTTPS upgrading, active content blocking, tracking blocking, phishing protection, and similar privacy-oriented features. However, if you want true anonymity, we suggest you employ a powerful Private Internet Access VPN – it can encrypt all the traffic that comes and goes out of your computer, preventing tracking completely.
Lost your files? Use data recovery software
While some files located on any computer are replaceable or useless, others can be extremely valuable. Family photos, work documents, school projects – these are types of files that we don't want to lose. Unfortunately, there are many ways how unexpected data loss can occur: power cuts, Blue Screen of Death errors, hardware failures, crypto-malware attack, or even accidental deletion.
To ensure that all the files remain intact, you should prepare regular data backups. You can choose cloud-based or physical copies you could restore from later in case of a disaster. If your backups were lost as well or you never bothered to prepare any, Data Recovery Pro can be your only hope to retrieve your invaluable files.
