What is MergeDocsOnline? How did I get infected?

The program you are currently dealing with is what’s known as a browser hijacker. It’s only one of many other pieces of programming of its type. Its purpose is advertising and promoting various products, services, websites, etc. That’s why you are constantly subjected to the wild display of colorful online ads, and that’s also why your usual homepage and default search engine were replaced with new ones. That’s also how the software category of browser hijackers got its name. With that said, most of the time programs of this type are harmless and even fully legal. Yet nevertheless they get dubbed as viruses and that often gets people to panic, thinking they’ve been infected by something dangerous.

However, MergeDocsOnline is not a virus, but it can certainly be very annoying and even cause some unwanted effects, and we’re not even talking about all the ads. Browser hijackers are often categorized as potentially unwanted programs, because though they don’t aim to cause damage, they aren’t of any particular use to the end user. Instead, software of this type just tends to be using your computer’s resources to run its processes in the background. And these processes also include activities known as traffic data collection. Basically this means that MergeDocsOnline (or other browser hijacker) could be examining your browsing history and using it to optimize its advertising strategies, based on each separate individual.

Other rather questionable and even risky things that a program of this type could do include modifying certain registry files on your computer. This is especially important to consider, because though these modifications are intended to make the display of all the ads and the redirecting to various sponsored pages possible, they may also make your machine more vulnerable to external threats. Not to mention that being constantly sent to various web locations can prove to be quite dangerous and may expose you to viruses such as Trojans, ransomware and others. In addition, the background processes we mentioned can plain and simple just slow down your PC’s overall performance, making it more sluggish and even leading to freezes and crashes.

So, now you have plenty of other reasons, on top of your frustration, to see to the immediate removal of MergeDocsOnline. But now to answer the other fundamental question of how you may have gotten infected in the first place. Typically, software of this type is bundled together with other, more attractive for the end user programs, in order to ensure its distribution. If you have recently downloaded some program or game from a semi-reliable source, such as an open source download platform or other file-sharing website, that’s likely also how you ended up with MergeDocsOnline. So, in order for you to avoid this, you should be sure to use only trustworthy download sources, on the one hand. And on the other – take the extra few minutes to customize the installation process manually. Use the Advanced or Custom settings in the setup and read through each step. That way you will be sure to reach one informing you about added installs and possibly also giving you the choice to opt out of them.
