Suspicious-looking folders
I notice that recently when I go to attach a file to email, above "Recent Places" in the file selector list there are a bunch of suspicious-looking folders I've never seen before, named:
- WebArchiveCopyPasteTempFiles
- com.microsoft.Word
- fzp09ngngh2hvdnzgb...(and then a bunch of other seemingly random characters)
- T
- rt
- folders
- var
- private
Should I be concerned?
