What does it say under "details" ?
Ok, so first I went to: C:\Program Files\AVAST Software\Avast\defs\16092001
Then selected the file aswHdsKe.sys and I right-clicked, and choose "properties". (A window comes up)
Then I chose the tab "Digital Signatures".
Then I selected AVAST Software s.r.o and clicked
Details (A second window comes up)
My previous screenshot (

If I go further to "Countersignatures" and select the only line there, and then click
Details (second time). (A third window comes up). I get a similar screen as the last but where the signer name is "DigiCert SHA2 Timestamp Responder".
