1. Which antivirus are you using?
2. Have you installed all pending Windows updates?
3. When exactly do you get the error?

Hstar.exe with description Hidden Start is a process file from company Dell belonging to product hstart.

This issue may also occur if Wininet.dll file is corrupted, as this file is a module which contains Internet Explorer functions.

Yes, Malware can pose as a Windows Update; however, they do not enter through the Microsoft Windows Update notification tool. Malware through a Windows Update file will usually occur when browsing the internet, and you are asked to download a video codec from Windows Update, but, actually, is not from Microsoft. To avoid this, install all of the security updates, as these will keep 85% of all viruses and exploits off of your pc.
