A. Please scan your computer using your antivirus program.
I suggest you to scan your computer using the free version of anti-malware software. This will remove all of the malwares, spywares, viruses from the computer.
Note: If you have Anti-virus programs like Norton, mcafee, CA, kaspersky installed on the computer, still I suggest you to download and install Malwarebytes as the Anti-virus program does not remove Malwares generally.
Please open the following link and download free version of malwarebytes.
Please click download the latest verion on the top left hand side and install it.
After that, click Quick scan and click start.
It will take around 10-15 minutes to scan. Once the scan is complete. You will see a link, "Select All". You will click "Select All". After that you will click "Remove Selected"
Then you will see a pop up with options, Yes or No. Click Yes and this would restart your computer.

Now, restart the computer, login using the new user account.
Please try to open this program, by clicking start, all program.
