A BAT file is a type of Windows or DOS file that is used to execute commands via the Command Prompt. The yare usually created within a text editing application environment such as Notepad and can be executed at any time. Since this component is launched with the highest privileges on the system, the attackers can perform a variety of actions, which include:

  • Update malware with newest features automatically;
  • Install other malicious payloads;
  • Spy on the infected users' computers;
  • Steal personal files or sensitive details;
  • Reroute web traffic, etc.

Without a doubt, such operations on any Windows computer can very negatively impact each of the infected users. They could suffer from financial losses or even identity theft. If you suspect that malware is hiding on your computer, you should remove BAT.Kefi virus without delay.

You should not try to eliminate malicious programs manually, as these attempts could result in further damage to the system. Instead, employ a powerful anti-malware, such as SpyHunter 5Combo Cleaner or Malwarebytes, and scan your system thoroughly (note: access Safe Mode with Networking as explained below if you are unable to perform a scan in a normal mode). This way, you would ensure that all the malicious components are eradicated at once.

Also, since malware such as Trojans can create serious damage to Windows system files, it may start malfunctioning even after the infection is terminated by security software. If you experience crashes, lag, Blue Screen errors, or similar issues, reinstall Windows OS or employ ReimageIntego to fix virus damage automatically.

How to prevent from getting trojans

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.
