If your computer has been infected by Concom.exe Virus then you need to know you are dealing with an Adware threat. These malicious programs are characteristic for their ability to display unwanted Ads on the infected computer’s internet browser. The Ads will follow you on whatever page you try to load and they can be extremely annoying – especially if they have flashy animations and sound effects. The Ads will actively slow down your computer, especially if you have hte habit of keeping multiple tabs involved. Your computer has to download the data needed to display the Ads and then render them on your screen in addition to the content of the page. Especially on older machines this can cause a lot of delay on page rendering speed and it some cases even temporary hanging of the browser.


Name Concom.exe
Type  Adware or Browser Hijacker (can possibly be part of both)
Danger Level Medium or High
Symptoms Advertisements and Pop Ups imposed on the layout of each browser page
Distribution Method Largely software bundles that seem the same, but are often distributed through illegitimate channels
Detection Tool

How it got in?

There are multiple ways Concom.exe Virus may have used to infiltrate your defenses, but most of them rely on tricking you into unwillingly installing the virus yourself. This is usually done via an infected executable file, which will inject the virus in addition to whatever else it was supposed to install.

For this reason we advise you not to run executable files that are obtained from unsafe sources. This includes (especially) attached files to emails, but also torrent sites, forums, online storage sites and the like.

Installers for freeware/shareware programs also commonly include what we call a software bundle. This means that if you try to install said program using the default installation option it will also dump into your computer whatever other program is included inside the bundle and many such programs are Adware or worse. if you want to avoid getting your PC infected in this way in the future you should always use the Advanced installation option. It only takes a couple of more clicks and nothing can go wrong while using it. The benefits are that you get to see exactly what and where will be installed and you can uncheck any suspicious program from the list. This is in fact the most likely way that Concom.exe Virus has used to get inside on your computer.

Don’t click on the Ads and don’t install anything off an Ad until you remove Concom.exe Virus

You should still perform them to get rid of the entire culprit.


Our first step here is a reboot in Safe Mode. If you already know how to do it, just skip this and proceed to Step 2. If you do not know how to do it, continue reading:

Proceed to Step 2.

For W. 8 and 8.1 Users:

Click the Start button ,then Control Panel —> System and Security —> Administrative Tools —> System Configuration.Administrator permission required

Concom.exe Virus has likely infected all of your internet browsers and attached itself as an add-on. Now that you have Safe Mode ON we can do something about it. Proceed ot run Step 2 and Step 3 for every browser installed. If you decide to uninstall some old browser you no longer use make sure to clean it from the virus first. Also pay attention to any attempt by Concom.exe Virus to get you to install another program or send you to a remote internet site via a confirmation for deletion pop-up. It’s nothing but trouble.

Go to STEP 3.


Right click on the browser’s shortcut, then click Properties.

NOTE: We are showing Google Chrome, but the method is the same for all browsers.


Once you’ve reached Properties —–> Shortcut (on the band at the top), then in the Target type field, REMOVE EVERYTHING AFTER .exe.

Continue with STEP 4.


Hold the Windows Key and R together. Write appwiz.cpl in the new field, then click OK.


You are now in the Control Panel. Search around for Concom.exe Virus and anything else suspicious-looking. Uninstall it/them. Also, be extremely careful. Viruses often spend one last ditch effort to trick you into installing more of their kind. If you see a screen like this when you click Uninstallchoose NO:


Hold the Windows Key and R againbut this time copy + paste the following and click OK:

notepad %windir%/system32/Drivers/etc/hosts

A .txt file will open – don’t touch anything there. If you are hacked and someone has access to your PC, there will be a bunch of other IPs connected to you at the bottom. This is what a hosts file looks like:

hosts_opt (1)

If there are a bunch of strange IPs connecting to you below “Localhost” you may be hacked, and it’s best to ask us in the comments for directions.

Go to STEP 5.


Open the Task Manager by right clicking on the Taskbar and choosing Start Task Manager.


Once it opens, choose the Processes Tab. Look at all of the processes in front of you and try to determine which ones are a virus. Google them or ask us in the comments and we will provide the best assistance we can.


This is perhaps the most important and difficult step, you have to be extra careful and double check before deleting any files. Doing a mistake can damage your PC significantly, especially if it is a big one. If you are not feeling comfortable, we advise you to try the proven anti-malware program we recommend. It is perfectly capable of cleaning Concom.exe Virus for you and also for scanning for other problems that may precede Concom.exe Virus. There are some really nasty viruses out there that can ruin all of your data and demand upwards of $200 in payment as ransom.


Right click on each of the virus processes separately and select Open File Location. Also, End the process after you open the folder. Just to make sure we don’t delete any programs you mistakenly took for a virus, copy the folders somewhere, then delete the directories you were sent to.

Move on to STEP 6.


Take a look at the following things:

Type msconfig in the search field and hit enter: you will be transported to a new window. 


Go in the Startup tab and Uncheck anything that has “Unknown” as Manufacturer.

Type Regedit in the windows search field and press Enter.

Once inside, press CTRL and F together and type the virus’s Name. Right click and delete any entries you find with a similar name. If you can’t find them this way, look in these directories, and delete the registries manually:

  • HKEY_CURRENT_USER—-Software—–Random Directory. It could be any one of them – ask us if you can’t discern which ones are malicious, but bear in mind they are always different.
    HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random
