Best bet is talk to the Kaspersky people. Their program will have either quarantined or completely deleted the data files that Thunderbird stores your mail in. So recovery will depend entirely on what they did, and what they can do to undo what they did.

Or you could restore from your backup, if you have one.

Hi Matt, thanks for the reply. Think I may have 'mis-asked'.... The emails are LOST from the computer. I know that, I pressed the key that told Kaspersky to remove them from my system.....(Doh just was not in thinking mode, should have seen they pointed at the mailbox)

My question is really how do I reset TB to pick up the 30 days worth still on my ISP

I was hoping there was some hidden date saying that the last download was at 1605 today or something and I could reset that to 31 days ago..

Thats the sort of thing I'm after.

if it is a pop mail account. (and It should be to only have 30 days)

goto the Help menu (alt+H) > troubleshooting information and click the show profile button.

Close Thunderbird Open the mail folder in the explorer window that opened. Now the server folder for your account. It will be named the same as the mail server. delete the file popstate.dat Restart Thunderbird

Matt, Thanks for that, Excellent Worked a treat, Thanks very much. I must make a note of this... I have done it a year or so ago, as well. So knowing my luck i'll do it again.

It brought back a 1.5K files (including virus) (dealt with differently now). Was expecting more, but had not realised I'd set my retain to 14 days.

THANK YOU very much Regards

Tools menu (alt +T) > options > Security > Anti virus

Click the allow. This allows for all new incoming email to be written to a temp file before it is committed to Thunderbird's mail store. If it has a virus the file can be quarantined, Thunderbird burps an error about the file being missing and everyone is happy.

Now seriously consider creating an exclusion in the mail anti virus for the contents of your mail folder. You have fixed the new issue, but not the full scan problem. Considering that the virus could have been sitting quietly in your inbox for a year when the AV company finally decides to hammer it.

Thunderbird does not allow scripting. So even if there is a script virus in the mail it will not run. If it is in an attachment and you try and open it the anti virus will hit it as soon as it is written to the temp file. This must happen so Thunderbird can fire off the location to the helper application that actually opens the file. So again your protected.

Just some suggestions and food for thought.
