Google Drive should be scanned for viruses. In general, this applies to any cloud service. A very simple way to check whether a file on Google drive is safe or not is to analyze the URL. There`re tons of such services freely available. They make it easy to find out if the route to the file is dangerous or not. You should also have an antivirus, preferably a paid one. But some services don`t require checking. For example, I download google slide templates free from time to time, and my antivirus has never encountered viruses in them.
