Microcosmtab.com search results should not be trusted

Microcosmtab.com virus is an untrustworthy third-party program that adjusts browser’s settings to force the user to use a strange search engine[1]. Once installed, it adds an extension called Microcosm New Tab, and it’s icon (an upwards-pointing arrow) will appear in your browser’s menu. Clicking it launches a new tab and loads chrome-extension: //nagnmfhgkjkplbhplkbicmpkfopmnefp/newtab.html URL. Near the address line, you will see the name of the extension (developed by Microcosmtab LTD). When analyzing it, we discovered that it has quite a lot of permissions – alongside traditional “read and change all data on sites you visit[2],” it also encroaches on the rights to read and change user’s bookmarks and know one’s email address. You should remember that email address is considered to be sensitive information because scammers can easily add it to their list of contacts that will receive huge amounts of spam[3]. There are various dangers regarding spam emails, and one of them is ransomware – you should be aware of it. We do not say that the developer of this browser hijacker is involved in illegal activities, but keeping sensitive information to yourself is always a good idea. If you feel that this application shouldn’t stay on your computer, you might start thinking about Microcosmtab.com removal. More information about it is provided below.

Questions about Microcosmtab.com virus

The new home page address we described earlier provides a search engine with an animated background and also some information about weather in the area that user lives in. The overall look of this search engine looks okay, and it even reminds us of Google’s default homepage (because there’s Gmail, Images, Video buttons and even alert and gear icons that look exactly like the ones on default Chrome’s home page). Our biggest concern is the search engine itself – it seems that it serves a lot of sponsored advertisements to users, which means that it seeks to cause redirects to them and generate pay-per-click revenue[4]. Unfortunately, external websites advertised by potentially unwanted and untrustworthy programs can be dangerous. Be careful when visiting them, and make sure you do not inattentively agree to install some shady programs or provide personal information somewhere. If you want to use a more trustworthy search engine, better remove Microcosmtab.com using anti-malware programs like ReimageIntego and change homepage settings as explained in the tutorial provided below the article. The tutorial also explains how to uninstall the described hijacker manually.

Distribution of browser hijackers and tricks used to implement it

There are several ways to distribute Microcosmtab.com redirect virus. First of all, you can download it from its official website. However, users rarely come across it by their own wish, so we assume that some adware programs might be causing redirects to it and suggesting users to try the extension provided by that page. Alternatively, this browser hijacker might get into computer system alongside freeware such games, download managers, and other programs that people sometimes download from the Internet. It is vital to know that freeware usually contains a few “surprises,” also known as bundled software[5]. These bonus programs usually present themselves as “recommended third-party programs,” however, statistics show that they typically are useless ad-supported programs. You should choose Custom or Advanced settings and deselect provided suggestions to install extra programs.

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
