TravelBook

TravelBook tries to entice users with its offer of providing relevant and useful travel-related information. Unfortunately, apart from the described functionality, TravelBook also is an ad-supported application that is being spread through questionable distribution methods. This classifies it as adware and a PUP (Potentially Unwanted Program). Users rarely download and install PUPs willingly. In the vast majority of cases, these intrusive applications sneak themselves unnoticed by employing tactics, such as bundling or fake software installers. Users also should be on the lookout for other PUPs, such as MinePass, Reputation Lookup and ElementSignal.

The presence of TravelBook on your computer or device could diminish your browsing experience significantly. The application is going to generate numerous dubious advertisements that could even be injected into unrelated websites creating the impression that they originate there. The advertisements could take advantage of clickbait or social-engineering tactics to lure users into engaging with them. Afterward, they might redirect to unsafe pages running online tactics, performing phishing or spreading more PUPs.

In addition, TravelBook could be collecting various sensitive information in the background silently. PUPs are notorious for monitoring the user's browsing activities and then sending them to their operators. The collected data could even include numerous device details, and in the most threatening cases, debit/credit card numbers and payment information may be collected from the affected Web browser.
