Avast detects Rootik, but does not remove it

avast internet security detects rootkit on my laptop, when I choose to delete it and hit save, it prompts be to do boot time scan, restarts the computer but doesnot find anything during the boot time scan. And when i start the computer back up, and scan it again, rootkit is there.

Help needed

thanks

what is the name and loaction of detected file … full file path

Just ran a full system scan again. It found two rootkits. Below is the paths

C:\windows\System32\autochk.exe:BAK
C:\windows\winsxs.… \autochk.exe:BAK

Severity for both is High.

When I click apply, it asks me to do boot time scan, and the process continues, doesn’t find anything during the scan. But when the computer is back up again and i do a full scan, it shows up.

For clarity I have also uploaded a snapshot of the log.

Upload autochk.exe:BAK to www.virustotal.com if tested before, click rescan for a fresh result
