Laptop attempts to install unknown document viewer on start-up

Asked By 40 points N/A Posted on -

My laptop attempts to install a document viewer every time it is powered on. It does this on its own. Whenever I click on Cancel, I have to do it multiple times because it always appears. After a while of clicking on Cancel an error message would appear "An unhandled exception has occurred in a component in your application. Click on continue and application will ignore this error and attempt to continue.

Object reference not set to an instance of an object." I can click on details or continue on the message but nothing happens when I click on continue, the message is still there. I have to forcefully end it by going to the Task Manager and end its process from there.

Does anybody have a solution for this problem?

I desperately need your help with this.

Thank you.

Hi there Chad!

It seems that your laptop is having unusual behavior, and this symptoms only shows that is infected with a virus.

Well, the best and efficient thing to do is to install an anti virus, so you can scan your system thoroughly. I suggest that you use Avast, it can detect malwares, or worms. In your case, avast can avoid this thing clicking "Remember my answer to this" when the notification of installing of this occur, so it won't appear again.

BUT, if it continue to happen, and something wrong happens in your laptop like suddenly reduce of its speed, not working application, you must format you laptop so it the virus won't spread your system.


Hope this help!

God bless.

That problem is with one of your startup programs that try to update on Windows startup. To fix this, you need to figure out which of the startup programs do this. Download the free version of CCleaner and install it. Once installed, start CCleaner then go to “Tools” on the left pane and select “Startup” on the right.

Now, you need to do this manually and by trial-and-error. In “Windows” tab, select the first item on the list then click “Disable”. Close CCleaner then restart the computer. Log in to your account then see if the problem appears. If the problem is still there and your computer still tries to install a document viewer on startup, go back to CCleaner then disable the next item.

Re-enable the previous item then restart the computer. Keep doing this until you located the application. Once you located the program, uninstall it. Download the free version of Revo Uninstaller and install it. Once installed, start Revo Uninstaller then select the culprit program among the applications and click “Uninstall”. Follow the normal uninstall process. When you are prompted to restart the computer, click to restart later.

When uninstall is complete, click “Scan” to scan your computer for any leftover files and delete everything it finds. This removes everything the program created on your computer. When it is finished, close Revo Uninstaller then restart the computer.
