OK good so I can see the last pop up.
how do i see all the pop ups?
You can't only the last one is retained.
You will have to check the log files, what shield was it that did the detection (I suspect the Web Shield) ?
If so, then check the C:\ProgramData\AVAST Software\Avast\report\WebShield.txt - this file location is for win7 and later.
