windows can't find file

I have three recent problems. Wondering if they are all virus related.


1st. Every time I log onto my desktop I get a small page opening up called tasking.exe. Nothing written on the black screen. This started a few days ago


2nd. I am using RoboForm start page and have favourite logins saved on that page. I can no longer click on these and login. I have to use RoboForm on the toolbar. This started about 2 days ago


3rd. Today when I log on I am still getting the screen in 1st..above. I also now get another window that says
Windows cannot find 'C:\Users\Darlene\AppData\Local\GeniusBox\client.exe' . Make sure you typed the name correctly and then try again.
