Hi about a week ago we noticed an extra window opening up when using goggle chrome, always advertising products we have used. it was today I noticed very quickly that before the ad fully loaded the address bar had click.cpvrdr.com writen in it. I goggled this and found this site to help remove it. I have followed steps 1 2 & 3. However when trying to do step 4, JRT.exe my compter came up with this message "Windows cannot access the specified device, path, or file. You may not have the appropriate permissions to access the item" although I am an Administrator account user. Can this be fixed or can this step be skipped. Thank you in advance for any advice you can give me.
