During a download the file is scanned to detect a virus ?
Depends on how you download and the settings in Avast.
…then not so easy . I download from a site when I need some software or to save a web page on the HD.
I’ve not done any settings till now… :
on-access control panel > standard shield > customize > advanched > enable “scan created/modified files”
This will let Avast scan them.

It’s better to set ONLY some extensions or all files ?
The choice is yours
Are there performance problems ?
Ok, your settings are correct 
Yes, some lack of performance as each file will be scanned while opened/changed/read :-\
Thanks.
In “scan file on Open” what extension is better to type ( or copy /paste if it is possible…) ?
It won’t help as the scanner, in Home version, will only scan the file ‘as a text file’, searching the strings of viruses.
You will better protected with a Script blocker application (see ‘Links’ on my signature) and adding ashquick.exe to your donwload manager. You won’t have the lack of resources
ashquick.exe can be launched from explorer menu …
I use it currently after having downloaded a file …
But I thought of a tool that worked during the download and blocked it in case it detected a virus…
Then I have noscript.exe by Symantec .
Script blocker should be in the pro version…
Regards.
Set the sensibility to ‘High’ and standard shield could do the job.
Yes, but there is a lot of free script blocker applications that could be used with avast.
See ‘Links’ on my signature for Script Sentry and Script Defender (best in my opinion): http://www.analogx.com
Thanks a lot.

I’ve uninstalled some month ago script defender because it doesn’t work! I have WinMe. I had some little script *.vbs and *.js that worked very fine without being blocked !
…while noscript.exe by Symantec http://securityresponse.symantec.com/avcenter/venc/data/win.script.hosting.html blocks them (but block ONLY .vbs and .js extension ! )
Maybe it was only a my problem…someone has really tested this tool ?
Regards.
Sorry, this is the first time I’m hearing about this tool… :-[
Ditto, I have had no problems with Script Defender. I even added other file types to its list of intercepts.
All the program is doing is acting as a hand off to the program that would normally run the script, nothing special. It changes the file type associations for the file extension, so windows opens Script Defender (SD) and asks if it’s OK, then SD passes the request to the correct program. So there is not much to go wrong.
You are saying that at any file open SD is called ?!?
It should be a big overload ! Where did you read how it works ?
He’s saying that all the files - but only these ones - which extension you set into SD will be scanned. If you add the extension *.doc, all Microsoft Word Documents will be scanned by SD due to the file type association will be with SD and not Word.
It won’t scan files which extension were not added in SD list.
No! only script files that are part of the default SD list or other file extensions that are not in the default list that you would like to be intercepted. You only add those that you believe to be a potential threat.
It is no overhead at all, I rarely have it pop-up at all and even then it is for protection. You have to decide what you want protection or convenience/overhead.
I learnt how it worked simply by experience of using the program. If you click on a file that has an extension that is in the list, SD pops up (so it must be intercepting the windows file associations) and once you say it is ok to execute the script, etc. the program/script is executed/run as normal (so SD must be passing off the file to the original program that would have been called).
OK. then SD for the files in the intercept list ask if the program that asked them can be executed .
I had never had this pop -up !
I’ll try again…Thanks.
