Hello DavidR,
The Avast! Free version is 6.0.1000.
The Netbook came bundled with "Trend Micro" which I uninstalled successfully from Control Panel "Programs and Features", before installing "Avast! Free Antivirus" and "ZoneAlarm Free Firewall".
The only other security application running in memory is "Windows Defender". Other than this, I have "Spybot Search & Destroy" and "SpywareBlaster" which do not run in memory.
Hello Eddy,
If you open Avast! and look at "Real Time Shields" there is only one Shield which ought to affect this situation, which is "File System Shield". No doubt the issue would disappear if I were to disable its option: "Scan documents when opening", or disable the more specific options from its "Expert Settings" button, but of course I would prefer to not lose this function.
"Microsoft Office" appears to work without any other issue and as I have already indicated the problem appears to source from "Avast!".
"Avast!" also, appart from this problem, appears to be working normally.
Therefore I am reluctant to do a repair for either of these, in case this causes more problems, instead removing this issue!
Hello doktornotor,
Thanks for the image, but I would rather not turn off this function, if this issue can be solved some other way.
I am wondering if anyone else has encountered this problem, and whether perhaps it is a bug in the Avast! software that Avast may need to consider correcting.
Thanks and regards to all,
