How to remove Semptum.com (Virus Removal Guide)

Semptum.com virus

Semptum.com virus is a browser hijacker infection that modifies the shortcuts for internet browsers installed on the computer. The infection changes the browser shortcut so that the browser will point to a batch file when launched rather than the browser’s executable file.

semptum.com virus

The Semptum.com virus utilizes various potentially unwanted programs to make changes to browser settings and later the browser shortcut. Once these programs are installed they will replace the existing homepage, new tab page, and search engine with http://page-ups.com/all/ (or other URL).

This will cause affected web browsers to start-up on and redirect to semptum.com/HTWfjz (or other URL) and then to one of the websites listed below:

The programs used to change browser setting will also set the browser shortcut to open on a batch file that may represent one of the domain names listed above.

A concern with this infection is that the programs used to modify your browser settings  typically bundle with or are advertised on websites alongside other malware and potentially unwanted programs. This means that there is a good chance your computer is infected with other threats that should be eradicated immediately.

In order to remove semptum.com and stop redirects to the website it is recommended to scan your computer for malware that can remain hidden on your machine and remove rogue browser extensions.
