Privacyassistant.net virus has two identical versions: Ext.privacyassistant.net and Search.privacyassistant.net

The example of privacyassistant.net search engines

Ext.privacyassistant.net is a questionable search engine that belongs to Privacyassistant.net browser hijacker's[1] family. This bogus search tool spreads in software packages as SearchAssist extension for Google Chrome. After the direct or indirect installation, it alters browsers settings and controls user’s behavior.

However, the developer promotes Privacyassistant.net as a useful tool that enhances browsing experiences and offers to design your homepage as you prefer by changing background picture or placing favorite links. Sadly, it can infiltrate the system secretly and cause unwanted changes.

The Privacyassistant.net hijack occurs as soon as users download software package with this PUP[2] inside. Since then user’s homepage and default search engine might be set to Ext.privacyassistant.net or Search.privacyassistant.net. Despite different domains, these search tools are identical.

When users find hijacked web browser, the first instinct often encourages to go to the Settings and replace these modifications. However, Privacyassistant.net virus is developed in the way that users cannot simply delete this domain and type their preferred. The hijacker rejects all users’ attempts to set their preferred homepage or search engine because the developers are interested in forcing people to use it as long as possible.

The hijacker tries aggressively remain on the browser because it works as a marketing tool. It promotes third-party content or boosts traffic to the promotional websites. The problem with this sponsored content is that some of the links or ads may redirect to the potentially dangerous sites where you can get infected with ransomware, tricked by tech support scam or become a victim of other cyber crime[3].

Apart from Privacyassistant.net redirect problems, this search engine does not perform its primary function properly. Search engines are supposed to deliver accurate and objective search results; however, this one has nothing in common with objectivity.

Some of the organic search[4] results may be eliminated from the results page. Instead of them, you may receive some sponsored third-party links. Besides, in the Privacy Policy developers reveal about the partnership with Trovi Search which is a quite popular browser hijacker.

Therefore, if you do not want to browse through potentially dangerous commercial content, you have to hurry up and remove Privacyassistant.net from the computer as soon as you notice it. Powerful anti-malware tools, such as FortectIntego, can eliminate it within several minutes.

Hesitation is not recommended because the hijacker might collect non-personally identifiable information[5] about the users. Based on this knowledge, developers can display even more tricky targeted ads. Thus, do not delay this important task and start Privacyassistant.net removal right now!

Versions of the Privacyassistant.net virus

Ext.privacyassistant.net. This version of the browser hijacker is identical to the original version of the search engine. It has the same designed, features and infiltration method. After the hijack, it sets its domain as default search engine or/and homepage. It might also modify new tab URL address and disturb browsing sessions by displaying intrusive online ads.

Ext.privacyassistant.net removal is crucial in order to get take back control over the browser. However, it might be complicated because the PUP might alter browser’s settings and install various third-party components to strengthen its presence.

Search.privacyassistant.net. This search tool differs from ext.privacyassistant.net and privacyassistant.net only by its domain. The hijacker also spread via SearchAssist extension and might alter browser’s settings. After the hijack, users cannot access any reliable search provider from the browser’s startup page; they are forced to use search.privacyassistant.net.

However, just like the original version, this search tool might also display paid links at the top of the results page and in this way trick users into visiting potentially dangerous websites. Therefore, hijacker’s removal is crucial.

Shifty distribution method of shady search engines

Ext.privacyassistant.net, Search.privacyassistant.net, and Privacyassistant.net search engines spread in software bundles, or in other words, along with freeware and shareware. Every program downloaded from the Internet may include optional applications attached to it. However, you may not be informed about them if you choose wrong installation setup.

The most popular and widely used Quick/Recommended settings are not reliable. Instead of disclosing extra applications, they install them by default. Therefore, the hijack may be a surprise for many inattentive computer users. In order to avoid unwanted and unexpected presents, you have to get used to installing new software under Advanced/Custom setup. Then, you can see all additional programs that are offered to and reject their installation.

These search tools become default search engines when users install SearchAssist browser extension. Thus, to avoid undesired changes and browsing-related problems, you should stay away from this program.
