Thanks Scott for replying. I knew it was doing something along those lines, but I just don't know why it was from c:\suspect folder and why it happened when it did. Because while I did try to submit the file to avast back on the 28th, I tried to submit it from the virus chest (with the right-click>email to avast option), not c:\suspect. So I'm not sure why it was uploading from c:\suspect (which is a folder I created because of this suspected virus so I could manually upload it for testing purposes). And I don't even think I had any files in c:\suspect at the times it was uploading. It didn't make any sense.
Ultimately what I ended up doing was uninstalling and reinstalling avast just in case I had messed something up with it.
