I have security issues in my Dell Inspiron laptop (Windows 10 home):
- When I open windows update, some updates are not completed and some are blocked. And I get this message:
There were some problems installing updates, but we’ll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x80070643).
-
Windows security center service can’t be started in safe mode.
-
When I had Kaspersky free, I got warnings: some protection modules are corrupted and the protection is paused.
-
when I open a software (Edge, PDF…) and even when I open Settings, I always notice that the windows flash.
-
When I work in Battery Saver mode and shut down my laptop, the next time I start it I find that the battery level is low and the Battery Saver mode is still enabled! I restarted the pc and found Better Battery and not Battery Saver! So I conclude that my laptop doesn’t really shut down! Besides, sometimes when I start it, I get the following alert: alert the AC power adapter wattage and type cannot be determined. the battery may not charge.
After some investigation, I have a doubt about ExtExport.exe (a file of Internet Explorer), especially after reading this article:

Here are the file properties:
So, I uploaded ExtExport.exe in VirusTotal.com and got the following report:

Could an expert check it please? Is the file safe? What causes the issues mentioned above and how can I fix them?
Thank you
