Get this error when trying to reinstall Windows Defender. Defender does not work on this laptop. Get the following error Application failed to initalize: 0x80070006. The handle is invalid.

Do you already have it installed on your machine ?
If so you need to completely remove it first.

I tried to delete it and get an error message. Invalid Drive E:\

This computer did have malware and may still have it.

In that case time to get another scanner.

Running now, has not found anything in the 20 minutes that it has been running. Suggestions for a "free" virus protection. Wanted to use the Microsoft product, but still getting the E:\ drive error.

Thanks.

When I ran the Malewarebytes program it did not find anything, however, I was then able to load the Microsoft Security Essentials. Should I delete the Malwarebytes program, or is it okay to have it and Essentials running?

Not sure why the drive E:\ error message went away, but it did.

Thanks for your assistance.

They do different jobs.
It's fine to have both installed, but only run one at a time..
