Users might find it useful if you described what useful information would be relevant and/or what relevant information would be useful,
The following is what anyone who has to do technical support would consider somewhat relevant information:
OS Version
Browser and Version
URL of page where error occurs
Screen Shot of Actual Warning
Diagnostic information from the actual warning.
Version of Avast
Anything more than, "I get a virus warning" would be considered helpful and relevant information.
If you went to the car mechanic and said, "my car makes a funny noise, fix it" what would you expect them to do?
I don't use Avast, I don't get any warnings, I checked our site diagnostics, and find no malware, so what should I do for these reports?? There's not much to go on, even from Don's screen shot of the warning, as it contains no diagnostic information. In Don's case, clicking on the "MORE INFORMATION" button on the warning, and posting a screenshot of that would have helped much more than what was posted.
In addition to the millions of posts on scubaboard, there is content from other sources re-posted on scubaboard, and additionally there are ads from Google and third party ad providers that have the potential for malicious sources. Also, if you have malware already on your computer, it's possible that something on one of the pages triggers a report / warning.
Most of that is beyond my control.

Finally, as stated already several times in this thread, the problem is most likely Avast itself... Make sure you have the latest version of the software.
Since several people have stated that updating their definitions and version of the free virus scan software has solved the issue, I'm considering this issue closed. If people have new issues with virus warnings, I would recommend posting a new thread.
While I'm happy to help with issues relating to ScubaBoard itself, there's not much I can do, or will do to solve issues on your computer that are unrelated to ScubaBoard.
Thanks again.
