How to remove (uninstall) Start4u

Adware, such as Start4u became very widespread last year. Suchlike tools differ from plain malware in that their activity cannot be determined as really viral. There are many promises proclaimed and the features described on the web-site of this tool, but do you really think, that you can trust them? Every hour, banners and advertising are becoming more and if you want to eliminate Start4u - you will fail, because Start4u restores itself after removal. In this item, we want to tell you what is Start4u, how to uninstall it, and how to protect your machine from viruses in the future.


Advertising-oriented programs are a separate group of viruses, called adware and hijackers. The first ones affect the entire machine, placing pop-ups and other promotional information in the browser and even if the browser is closed. The second group acts exclusively in the browsers by changing the search results, providing false output and sending you to suspicious web-sites. All of these kinds of programs are supplemented with detailed descriptions of their features, and the user thinks that they are worthy. The condition of your PC is getting more lamentable according to the time that malware had dwelled in it. In the end, you'll understand that the workstation is wholly overwhelmed with all kinds of strange, hazardous or even harmful software. Restarts, spontaneous shutdowns, the poor performance of the PC, fatal errors and low speed of response will become very frequent. When the machine arrives into suchlike condition, users begin to look for an answer, and understand that it was desirable to uninstall the adware at the beginning, or not to download it at all.


There are few things that need to be performed, before Start4u can do its work. This is a kit of deeds aimed at defense against disposal. The browser is the secondary object. Search system, and home-page are changed. Browser shortcut properties are switched and the systems which regulate the amount of advertising are switched off. Most browsers now have a function that hides the pop-ups, banners, intrusive animations and other types of hype. Start4u deactivates these services, and you understand that the quantity of ads in all browsers is extremely high. In addition, to that the quantity of advertising has grown up observably, its quality has decreased. If malware functions on the workstation for 5-7 days, customer simply can't use the Net because of banners, hype and redirections in all browsers and sometimes even to turn on the laptop. For what is this done? All actions of virus are aimed at one object: to force you to make a click. These links often lead to third-grade sites offering low-quality goods, or services. Those web-sites are simply not visited by anybody except their proprietors, and the only chance for them is to bait users to the site with the help of such tricks. Any try to purchase something from suchlike site will cause serious problems. As you already realized, Start4u is harmless in itself, but it allows the man to perform actions that will cause damage.

Advantages of different removal methods


How to protect the computer?

To prevent infection by such program in the future, you need to realize closely in which way Start4u got into the workstation. Hijackers use lots of ways, but they all can be separated on three basic groups:

  • Infection through a malicious web-site. When you are on a web-page, you see a confirmation to download some programs, which would greatly support you in something. Such tools have the bounded list of advantages: providing the information about best deals on the Internet, the enhancement of Web surfing, showing the newest unpaid media-content such as movies, music and games, acting download of all drivers and updates for your gear, the fulfillment of certain tasks in the social networks. If on some web-site you find a suggestion to download the software with similar functions - it is really malicious, and the web-page itself is suspicious.
  • Adware might be bundled with worthy programs. Literally every unpaid software suggests you to get something besides the tool that you want. You download the tool, and then you see the window with the suggestion to install the anti-viral program, super-useful file manager, browser, the new add-on for it, and God knows what else. The checkboxes are already filled, and if you press "OK", the installation launches, and you’ll earn 2-3 programs that you do not need, except the one that you want to install.
  • The straight installation by user. Carefully composed description of the product and its useful (and nonexistent) advantages misguides the customer, and he sets up the tool.

The infection via viral e-mail attachment is also very efficient, but this manner is used mostly by ransomware and viruses, and not by advertisement software. If you see these words, we think, that Start4u is gone for good. If you prefer the disposal in manual manner, you should know how to understand that your computer has malware.

  • Slow boot of Operating System. Most of the adware, during the installation, tune themselves to launch at startup, regardless of whether you need it or not. Check the taskbar, and search for harmful programs.
  • Appearance of ads in on every site. If the amount of ads has grown up noticeably - that is, most likely, adware or hijacker.
  • Critical failures while using software, reboot or shutdown of a workstation without the user's resolution.
  • You notice many installed tools which you haven't installed. If the software appears on your machine without your resolution - it's, nothing else than the virus.

If you find one of the described above red flags on your computer - you have to make an overall scan through removal software, or manually get rid of all the useless and malicious software from your machine. Don't believe in everything you see on the Internet, look for the symptoms of infection on your PC, and it will be ready for anything.
