Avast perhaps?

Dear Matt,

Thank you for your attention to my posting about my sudden inability to attach files (regardless of type -- .pdf, .txt, etc) to my outgoing Thunderbird e-mail messages. I don't think your thought applies here.

Here is some additional information:

1.) I am running t-bird 38.1.0 under W7 (which I keep up-to-date with the latest patches).

2.) I have been using T-bird for years and have sent out literally thousands of messages using this e-mail tool, and perhaps 5% or so have had attachments that went through successfully.

3.) Throughout the years I have always used Symantec NIS as my sole anti-virus, etc security tool.

4.) Here is how my problem manifests itself: I click on "Write" to compose an outgoing message. At some point during this process I will also click on "attach." Normally -- as you know -- I am then presented with a Win Explorer - like window that allows me to browse to the directory and file which I desire to attach to the e-mail message. I select this file, and it is automatically attached to the message. This has behaved flawlessly throughout the years. But suddenly, last Thursday I believe, clicking on attach no longer brings up the WE browse window. Instead, the border surrounding the e-mail message window (which came up in response to my clicking on "write") blinks (highlights?) twice in rapid succession, as if the t-bird program is complaining about something. And that's all I get. No browsing window or anything.

5.) I have uninstalled t-bird and re-installed at least twice.

I do hope you have some further thoughts.

I think your issue may well be NIS. Restart the operating system in safe mode with Networking. This loads only the very basics needed to start your computer while enabling an Internet connection. Click on your operating system for instructions on how to start in safe mode: Windows 8, Windows 7, Windows Vista, Windows XP, OSX

Does it work any better in safe mode?

Dear Matt,

I followed your advice.

In safe mode, t-bird does attachments just fine.

Then, when I restart in normal mode, it goes back to its old ways (see the details concerning these "old ways" in my last post).

Do you believe this implicates NIS? I have been using NIS for years and years -- with t-bird -- without problems. What could have changed?

Steven Bass

yes I think NIS is the issue.

'NOTE I do not use any Symantec product and have not for more than a decade so specifics are beyond my ability.

First try turning off Sonar. I see it mentioned a lot so try that. Also disable out going email scanning. Pretty pointless process, if you have no virus, they do not spontaneously appear so scanning outgoing mail is pretty questionable really.
