It can change computer settings and files; create new folders; download and install other malicious software onto the infected computer; redirect web-browsers to malicious, scam and spam web-pages; use the computer for click fraud and other dangerous and harmful actions.

Any malware is a serious threat. Trojans usually infect a computer with other types of malware. Trojans can download and run other very dangerous malware such as ransomware and cryptominers. Especially dangerous are ransomware that secretly encrypt the victim’s files and then demand a ransom to decrypt them. The recovery of encrypted files becomes impossible in most cases. Ransomware can lead to the loss of personal documents and important data.
Cryptominers are malware that uses computer resources to secretly mine cryptocurrency. This process uses up a lot of system resources, which means that it slows down the speed of the computer. Moreover, cryptominers can lead to overheating of the main components of the computer and their failure.
Trojans are also used to infect computers with browser hijackers and adware. This malicious software is less dangerous than ransomware or cryptominers, but it causes intrusive ads and unwanted browser redirects. In some cases, Trojans have capabilities that allow criminals to remotely control the infected computer.
To summarize, the presence of MSIL/TrojanDownloader.Agent trojan on a computer can lead to serious problems, loss of personal data, large financial losses, damage to computer parts, and much more.
