Hi Rose :
I thought you were a lot sharper than you are posting ;
the Avast "Warning" screen says this is on your "D" Drive.
Are the 2 Acronis & the "Easy CD...." on your "D" Drive ?
What is on your D Drive ? On the Avast Warning screen,
there is a "More info....." ; did you click it ? What specifically
does it say ?
Have you done a Google Search for "Errorguard.exe" ; I
did and the 1st page lists lots of possibilities to look into
ONCE you have the info from "More info....."
So you had "Techie" work on your Desktop as well as
"redo" the laptop ?
