I keep having a msiexec.exe window pop up. Is this a virus?

I am not sure but do not delete or edit these things as they may be system files. Download Malwarebytes and scan, any malware found you should remove. Download "Security Task Manager" it will tell you what's and what isn't dangerous. Get all from Cnet.com. Do not remove anything from Security task Manager as it can be dangerous to. Good luck. Hope I helped.
