Good morning,
Avast 4.7 Pro in a detailed exam found a virus: " VBS:Kak-A1 [Wrm] ".
I accepted an alert of detection of a virus (from AVAST) by mail on November 20th, 06 at 10 h 22.
I sent in support@avast.com a message in French asking for help on November 20th, 06 at 11 h 32.
My first question is: how long time the support AVAST needs to answer me?
Is it one day, two days, one week or more?
Second question: Is it Absolutely necessary to write in English language to the support AVAST?
The virus was found in the zone of tidying up of the mail of Thinderbird, that is to say in the file Inbox with a volume of 374Megabytes. I do not want to erase this zone where are my mails for 5 years.
Third question: Can this file be repaired?
Thanks for your answers.
I am sorry, I dont speak english, I use a translation by @promt7.0

Whilst the language of the Forums is English, it makes it easier for those who help, but I don’t think there is a restriction in emails to support, however, you are likely to get a quicker response on the forums.
The FAQ of Thunderbird recommends that you don’t use your inbox for general storage as this is the most likely for corruption (as it is usually open if you have a crash), or an anti-virus may delete it (which you don’t want). The problem is the inbox is just a single file with all emails added to it, avast isn’t good at coping with the thunderbird format of the email boxes/folders. So it can’t extract an individual infected email and put the file back together again.
It is a painful process trying to find the infected email and manually deleting it and clearing the deleted email folder.
By all accounts Panda’s on-line scanner is able to do this, http://www.pandasoftware.com/products/ActiveScan.htm, I have never used this nor do I use thunderbird, so I can’t speak from experience, nor guarantee it will work. So I suggest that you back-up your emails so you can recover form a deletion of an inbox.
The downside of using the Panda’s on-line scanner is that it doesn’t encrypt its signatures so avast will detect them and alert, you will need to pause the Web Shield and Standard Shield providers, just before you start the on-line scan and start/resume them immediately on completion.
The Panda’s on-line scanner is places its signatures and other files in the System or System32 folder (depending on your version of Windows) these are in a folder called ActiveScan, so it is likely that avast will detected these later in an on-demand scan.
Well, that email is not, generally, for cleaning support. Besides, avast free version gives backup by the forum.
But, generally, few days are enough.
Well… forum language is English… but we can understand your English very good… don’t worry.
Well… generally you can’t clean TB inbox… so it would be good if you use more than one inbox…
Igor posted in the past:
The problem is that the Thunderbird mailbox doesn't really have any format. It's a concatenation of plain e-mail bodies, one after another. So, when avast! is scanning such a file, it detects the first message as an EML file (MIME format), unpacks its content and scans it.
If a virus is found inside of the first message and avast! is asked to perform an action, this (first) e-mail is modified (and the rest of the file is kept appended).
Now, however - Thunderbird keeps some kind of an index file somewhere else (which probably contains informations like where the particular message starts in the original file). When this index file mismatches the actual content of the file, Thunderbird is unable to read the files (and probably also to rebuild the index?).
as my friends Tech and DavidR have said, you will need to turn off avast “On Access” protection while running a free Panda online scan, you also need to use Internet Explorer to run the scan.
