Well, what if you browse to an infected file?

Well that is how I first noticed this in the first place, checking out a site someone considered was giving a false positive detection. I usually use the firefox virustotal add on and send the unp99999.tmp file to VT for analysis. I also open it in notepad looking for suspect ,Script or <iframe tags. But the corresponding (or any) unp99999.tmp file wasn't present.

Well a test at the second eicar link to the eicar.com file alerts, but not an Ask but direct abort.

http://www.eicar.org/anti_virus_test_file.htm
Web Shield Test - http://www.eicar.org/download/eicar.com.

So I went checking my avast settings and I don't know why but my Web Shield is no longer set to Ask. So that would account for a lot of my issues. But I would have though I would still be seeing the unp99999.tmp files whilst normal browsing.

I have no idea why this setting was left at abort connection, I did a clean install after the beta but I went round the shields setting them to Ask, so I don't know if I missed this one or didn't OK my way out of the Expert Settings.

On changing the settings back to ask, I can see the offending unp99999.tmp file again, but during this not a single other unp file was displayed however shortly.
