An item has been added to quarantine seemingly out of nowhere. It is c:\users\david\appdata\local\temp\i+0qlkup.exe.part To confirm the oddness it gives a date of 25.6.2011 (12.14) I'm not sure that I had WSA back then. I'll just remove it from WSA, it dosn't actually exist anywhere.
We have a known issue where the date of quarantined files is reverted back to 2011. This will be fixed in the next update, correcting all current entries to their correct date. That file looks like a temporary download so you should be safe without it.
