What is msvc.exe? Should I remove it?

Msvc.exe file is used for mining crypto-currency

Msvc.exe belongs to a Trojan horse that is used for mining crypto-currency. This malicious file might be dropped on the system together with free programs, and once it gets inside, it starts using computer’s resources to mine Bitcoins, Monero or other online currency.

The msvc.exe file can be seen in Windows Task Manager. The first suspicion about this process is high CPU rate. It uses around 20-30% of computer’s resources. However, stopping it will not solve the problem. Once you reboot the system, this process will be renewed.

Once the Trojan is installed, it immediately modifies or creates new Windows Registry keys to boot with system startup. Additionally, the computer becomes sluggish, and some programs might not respond or open. Thus, you won’t be able to use the PC normally until you remove msvc.exe CPU miner entirely.

However, before you start msvc.exe removal, you have to make sure that it’s actually a malicious file. The file might also be related to legit Windows OS programs, such as VisualStudio. Thus, deletion of it might cause problems to the safe program.

The malicious file is typically located in this C:\Users\Username\AppData\Roaming\msvc. However, if you find it in another directory, you should obtain a reputable malware removal software, such as Reimage, and run a full system scan.

The majority of security programs identifies msvc.exe files as malicious under Artemis!3F1D85138F66, Trojan.Gen.2, Suspicious.Cloud.7.L, RiskTool.Win32.BitcoinMiner.gen or other names. Therefore, you should not experience any problems with automatic malware elimination.

The malicious file can sneak into the system unnoticed

Most of the time, computer users are responsible for letting malicious files or programs on the system. Thus, the msvc.exe virus is most likely to infiltrate the system when a user:

  • downloads illegal or corrupted program;
  • installs fake update form pop-up;
  • installs a bogus add-on or browser extension from a corrupted website;
  • carelessly installs freeware or shareware.

Security experts remind users to stay vigilant and choose credible sources for software or update downloads. Keep in mind that only official publishers’ sites include legit updates and program downloads. However, if you download freeware or shareware, you should pay attention to its installation as well.

Always opt for Advanced/Custom setup instead of Quick/Recommended settings. These settings allow seeing “additional downloads” that might be obfuscated potentially unwanted programs or crypto-currency miners.

Instructions on how to remove msvc.exe correctly

We do not recommend manual msvc.exe removal. Deleting only this file might not solve the problem in the long term. Miner might consist of several related components that might re-install this executable and continue malicious activities on the computer.

Therefore, you should remove msvc.exe automatically with reputable security software, such as Reimage. It will detect Trojan and delete it together with all related files. Thus, you have to look to in the problem from the broader perspective and get rid of the malware instead of the single file.
