Boot time scan

[REDACTED]

I have a windows tablet with a bluetooth keyboard Avast recommends I do a boot time scan which I did and found a virus and it give me a list of keys to hit to get rid of the virus however the keyboard doesn't work until the tablet is on. How can I run a boot scan with no keyboard?

Use a USB keyboard.

Thanks for the info but I was able to download an antivirus program from another company and it got rid of the virus and also 32 viruses that avast missed.

What is the name of that other av ?

It would be interesting what the other AV is considering as viruses, file name, location and malware name.

It would also have been helpful what avast found, both before and during the boot time scan.

Some will be considering registry entries as viruses, etc. A registry entry without an associated malicious file is just an orphan registry entry.

I also wonder if it wasn't a rogue av, 32 seems a lot off difference.

I ran a boot-time scan recently. No viruses were found, but there were corrupted files. I just click on the report file, copy and paste the directory, and go and delete said files.

Avast isn't saying they are infected, just that they can't be scanned and why, nothing else. The corrupted file is usually an archive file and for whatever reason avast is unable to unpack it and assumes it may be corrupt.

You shouldn't delete them.
