Things to keep in mind about Duba.com:

Duba.com virus is a cyber infection that you should be already familiar with. It belongs to one of this year’s most active branch of cyber infections known as browser hijackers. Though these viruses may cause some inconveniences on your computer, they are considered low-risk. Nevertheless, if you find one on your system, it should not be ignored. In this article, we will help you sort out the Duba.com removal quickly and safely.

This questionable Chinese search engine may replace the default start page and search provider on Google Chrome, Mozilla Firefox, Internet Explorer, and Safari web browsers. The problem is that it usually does so without requiring explicit authorization, which is why security experts have already labeled it as a browser hijacker and a potentially unwanted program. In most of the cases, Duba.com hijack happens right after installing a freeware because it is usually spread as an attachment of various free downloads. Once installed, it installs itself on Windows startup and corrupts some registries. Besides, hijacks web browsers and starts providing users with altered search results. Consequently, this search provider may present you with sponsored links in the priority of the search results and, therefore, make you visit affiliate websites without realizing that. This way third parties are trying to increase their page rank of sales. Unfortunately, some unexpected Duba.com redirect can make you visit an insecure website that may even be involved in the distribution of potentially unwanted program. At the moment of writing, this hijacker usually reroutes people to sogou.com and other unreliable domains.

In addition, this browser plug-in may be used as a data tracker. It may invoke tracking cookies on each of your web browsers and start investigating what websites do you prefer visiting, what data you enter in the most popular sites, what content attracts your attention, bookmarks, and so on. Such information is usually transmitted to third-party advertisers who may create customized ads and deliver them to you while you browse the net via Duba virus website. Thus, in order to keep yourself from landing on suspicious data and prevent your data from leaking to third parties, you should get rid of this hijacker without a delay. In order to remove Duba.com, use Reimage or another reliable anti-malware.

How do browser hijackers find their way to the users’ computers?

The majority of security vendors agree that Duba.com hijacker is usually spread bundled with other freeware and shareware. It is assumed that the biggest chances to end up with this search engine without even noticing it is when downloading free programs that are aimed at Chinese computer users. However, some of the security vendors warn that Duba.com is malicious and may enter computers via Trojans. We cannot assert that these assumptions are hundred percent correct, but if that’s true, you should be very careful and ensure that your PC’s security system doesn’t have loopholes. In case you want to prevent infiltration of software packages, you should always check Advanced/Custom settings of a freeware and opt out of “optional downloads” that it may carry.

Duba.com FAQ:

Question: I’ve been using Duba.com for a while but recently noticed that it is commonly redirecting me to doubtful websites over and over again. Is this search provider safe to use?

Answer: As we have already explained, Duba.com is a browser hijacker that is collaborating with suspicious third parties. It is primarily used for promoting affiliate websites, which, unfortunately, are not necessarily safe to visit. Usually, it makes people visit Chinese websites like, for instance, sogou.com or doubtful online shops. On top of that, some of the security experts claim that this search engine is distributed using Trojans. Therefore, if you have been using this search engine for some time, we highly recommend you to remove it right away.
