Remove pop-up on startup (Virus Removal Guide)

Tell your friends:
If you keep getting the pop-up on your PC that you are pretty certain that you didn't install yourself and you are simply unsure as to how it got there then, don't worry, because you are not alone by any stretch of the imagination. This is something that is known as a browser hijacker and the chances are that you will very soon find yourself desperately trying to uninstall this rogue program not all that long after you discovered it.

The Windows registry modification looks something like this:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run then it should be "CMD" running cmd.exe /c start & & exit.

If you have CCleaner, you can open it and find the modification under Tools > Startup HKLM:Run CMD cmd.exe /c start && exit

You can simply select it and click Delete. That's probably the easiest way to remove it.

Browser hijackers can be really quite annoying – and not only because they have you in a quandary as you try and figure out exactly where they came from. In addition to this you were more than happy with your existing tool bar, home page or browser (the things that browser hijackers most commonly replace) so where did this new version come from – and why? More to the point, how do you prevent one from foisting itself upon you again at some point in the future?

What exactly is and how does it infect you?

Browser hijacker are quite cunning – just like their malware brothers and sisters in fact – and will make their way on to your PC through a couple of different means. Some of them come pre-installed with a new desktop or laptop while others – and this speaks for the majority of them - are bundled with another software program that you have downloaded. Browser hijacker that displays pop-ups when Windows starts usually comes bundled with freeware.

What to do if you have been infected

First of all, don't panic! pop-up will not, generally speaking, do you any harm. Having said that though, you probably will want to get rid of it as quickly as you can because browser hijackers can be very annoying! All you need to do is to go to your desktop or laptop's Control Panel, click on Programs and choose the Uninstall or Change a Program option. Here you will be able to see the names of all of the software and programs that are installed on your computer – including anything rogue like the Potentially Unwanted Program. Take a good look at the list of programs and if you find something you don't recognize or recall downloading, you can choose to uninstall it here.

How to prevent a browser hijacker infection in the future

The problem is that browser hijackers can be packaged with pretty much anything – no matter how legitimate so that makes them hard to avoid. One thing you can do is to only download software from the publisher's website and be cautious about clicking online links and adverts in case they lead you to somewhere that has been compromised. To stop annoying pop-ups on your computer, you can use Autoruns for Windows or open up Windows registry editor, search for or and delete all entries you find. You can also remove this pop-up window by removing the start-up entry in the Windows Task Scheduler. I recommend using Autoruns or CCleaner. Once the problem is fixed, scan your computer with anti-malware software. Why? Because very often this adware comes bundled with adware and even spyware. There might be malware on your computer that you didn't notice yet. If you have any questions, please leave a comment down below. Good luck and be safe online!
