I find that I cannot install Avast 7 on my HP laptop Windows 7.
The progaram unpacks itself, then installs according to the install box, but when the Windows installer box appears, it stops and nothing more happens, and I have to force an end task to be able to do anything more with the laptop.
I have tried with both Avast 7 free and also Avast 7 internet security with exactly the same result. There is no other security software installed that could conflict, and after each attempt I have cleaned up with the Avast tool and also Ccleaner to get rid of any remmants of the program.
I have had to give up at the moment and reinstall my previous antivirus, which is disappointing.
Could anyone help me - as I would like to use Avast.
