I want to run a Windows Defender scan while running an antivirus scan. In my case I am using Trend Micro OfficeScan Antivirus with Windows.
Currently Windows will close and disable Windows defender if I start up another antivirus.
The reason why I want to do this is because I get laptops that have been infested and its my job to clean them for viruses. Normally I just started up a Virus scan and a Windows Defender scan. An hour later they both would be done.
Windows Defender sometimes finds things that my Antivirus doesn't. Its a peace of mind issue, it looks good on the IT reports.
