Avast doesn't remove these last few rookits
« on: November 07, 2015, 05:06:09 AM »
When I did a full scan Avast found over 500 infected files with rootkits. When I try to delete them all, Avast got stuck on a certain rootkit and doesn't finish deleting the rest. You can see where it got stuck in the attachment. The same thing happened three days ago and it makes me think the other ones were not really deleted when I rebooted.

Unfortunately Avast is getting a bit paranoid there, as they are files that have the characteristics of rootkits but are not as such.  They are part of the Lenovo restore system.. Set Avast to ignore them

CAUTION :  This fix is only valid for this specific machine, using it on another may break your computer

Open notepad and copy/paste the text in the quotebox below into it:

Save this as fixlist.txt, in the same location as FRST.exe

Yeah it's fine. How do I set Avast to ignore those restore files?

You can exclude the preboot folder from scanning
