NoBot is a portable spyware and malware scanner for the Windows operating system that focuses on detecting bots, spyware, and other types of malware.
The program scans the Windows Registry and also looks for suspicious file paths, and it can optionally interact with VirusTotal to have suspect files analyzed. A Pro version is available that can also check for module injection, startup tasks and more, however this requires a paid upgrade.
In the eventuality that you noticed your computer is rather sluggish and the browsers have a weird behavior lately, then NoBot can perform a scan and help you remove the malware or PUP responsible.
