I've been having this problem for quite sometime. A full scan will leave a list of files that can't be scanned due to password protected. i can't highlight them, delete or do anything. Then when i run a boot scan I get similar list but re-boot after that and it goes away. but then re-occurs a few days later.
It doesn't seem to harm anything except I've had my "outlook" contacts hacked and advert emails sent out to everyone but not asking for money, just phishing with "your paypal payment is confirmed" click here etc...
As the above poster notes, they all start with the recylce path but i can't find the file by searching the path so it's hidden somewhere.
thanks for any help,
