ESET Online Scanner is a fantastic free tool to detect threats without the need to install antivirus software.

The user is offered the option of deciding to either quarantine or delete the identified threats and may also opt to create a customized scan profile that click to find out more will examine specific folders and files. The program can be used offline, however you’ll need an internet connection to download the signatures and finish the initial update.
The program can identify many different types of malware, such as spyware, Trojans, and viruses. It also detects potentially harmful applications.
