As we said, despite being different and far less harmful from Trojan Horses, Spyware, Ransomware and other nasty and nefarious malware programs, the browser hijacker apps like Advfandom, Advatravel and Expo Captcha are still not the safest form of software that you could have within your computer’s system. The hijacker itself normally contains no malicious code and doesn’t have the ability to harm the computers it’s installed on. However, the main hazard for your virtual security are actually the adverts themselves. You should be well aware of the fact that you can’t trust every online banner or advert that you see on the Internet since you cannot know what their origins are and what they may be linked with. The same applies to the advertising materials that Advfandom or another hijacker app may show in your browsing program. Since the ads never really stop as long as the hijacker is operational, it is very difficult to avoid all of the advertisements. Therefore, the best option you have in such a situation is to eliminate and fully uninstall the invasive ad-generating application and in that way free your browser of the invasive commercial messages.
