TechRemove Zoomify Virus from your computer to stop pop ups in browsers

Nowadays we are getting so many pop ups showing advertisement or alerting you of virus infections which does not go easily. They keeps coming up after closing them and are very annoying. Some of them asks you to update flash player, Some would asks to update the browsers some would show your computer might be infected with virus while some would say the java Plug-in is outdated.

I am gonna talk specifically about Zoomify virus. It does not get removed easily and none of the security softwares detects it. I scanned my computer with ADWCleaner, Hitmanpro and Malwarebyte and ESET Online scanner when I already had my updated Norton antivirus ups and running. I was still getting the pop ups whenever opening any of the browser to surf internet.

Then after all the efforts, I tried to check the processes running in the Task manager and found some new and unfamiliar services running and when I tried to close one of them, it kept coming back to running state. I did not even allow me to delete the file associated with those services.Here is the snapshot of the processes running in the task manager.

When I searched internet to find out what these processes are and analysed them by some software, I found that this is a program which is associated with zoomify Malware and generating pop ups and redirecting browsers.This is a Virus.

How to remove it?

Troubleshooting Steps (TS): Before we start the following troubleshooting I assume you have already updated your current security or Antivirus software and scanned your computer with that.
Step 1. Run RKill to terminate any malicious processes
RKill is a tool that we should run before doing any troubleshooting on PC, this software will attempt to terminate all malicious processes that are running on your machine, so that we will be able to perform the next step without being interrupted by any malicious software and also if these processes are terminated the performance of the system would definitely increase a bit to allow you to perform action faster. RKill was developed at
You can download the latest official version of RKill by clicking here.Please note that we will use a renamed version of RKILL so that malicious software won’t block this utility from running.
RKill is available in different filenames because some malware will not allow processes to run unless they have a certain filename.
These link will automatically download RKILL renamed as iExplore.exe.

Double click on iExplore.exe to start RKill.


When RKill runs it will kill malware processes and then removes incorrect executable associations and fixes policies that stop us from using certain tools. When finished it will display a log file that shows the processes that were terminated while the program was running.Do not reboot your computer after running RKill as the malware programs will start again.

Now you can perform your troubleshooting steps a lot easier way.
