How to remove Search.bytefence.com virus

Search.bytefence.com virus

You may have browsed the web before and noticed many people and websites referring to something called the “Search.bytefence.com virus.” When people and websites use this term they are describing an occurrence when the ByteFence program changes your existing internet browser settings such as your homepage and default search engine and replaces them with Search.bytefence.com. By definition this is not a computer virus but it is a concern for many internet users.

Search.bytefence.com virus

Browser redirections to Search.bytefence.com usually happen when a new browser window is opened, a new browser tab is opened, or a search is performed in the address or omni bar.

The ByteFence program is detected by Antivirus programs as a potentially unwanted program (PUP) and adware according to Google’s Virustotal.com website. Malwarebytes Anti-Malware will detect ByteFence as PUP.Optional.ByteFence, Tencent programs will detect it as Net.Risk.Adware.Twcwc, and TrendMicro-HouseCall will detect it as Suspicious_GEN.F47V0409.

In addition, the program is questionable to many because of the way it is advertised. It is often found promoted by third-party software bundlers that also advertise malware, potentially unwanted programs, adware, spyware, and other threats. Third-party software bundlers oftentimes install additional programs without user consent or knowledge.
