Backdoor.Infexor is a threatening backdoor Trojan whose presence on your computer may often go unnoticed since this threat is not meant to display any harmful behavior. Instead, its authors have created it with a single purpose in mind – to gain persistence on the compromised computer and provide them with the ability to execute actions on the infected machine, as well as plant additional cyber threats. It is unknown how Backdoor.Infexor is being propagated, but it is likely that its operators may rely on more than one propagation technique to acquire more victims – spam email, pirated software, torrent sites, shady adult content, and game cracks are among the most popular content used to distribute cyber threats like Backdoor.Infexor.

When this malevolent program is initialized, it can drop its files to multiple system folders and then acquire persistence by either creating an auto startup Registry entry or using a custom-made Windows service to start when Windows boots up automatically. While Backdoor.Infexor is active, the attackers may gain the ability to exfiltrate sensitive details from the infected computer, plant additional malware, and manipulate the processes and programs present on the victim's PC.

Since Backdoor.Infexor is meant to act stealthily, it might be impossible to notice anything out of the ordinary even if your PC is infected. This is why the safest action to take to ensure that Backdoor.Infexor is away from your computer is to use an up-to-date and trustworthy anti-virus scanner at all times.
