I’m a newbie. Upon completion of the initial scanning, the message was that great number of files couldn’t be scanned. Mainly 3 different extensions: 1./ sbRecovery.ini
2./ sbRecovery.reg 3./ …/.txt. The last type looks like cookie. Question: What is going on?
It’s normal; avast informs you that it was unable to open the files (configuration files), because other application has an exclusive access to them.
They are a part of spybot S&D and are password protected, when you delete something using S&D it makes a copy to allow for recovery in case of accidental removal.
You could reduce this number by deleting old entries (if there has been no adverse effect for a week or so) from the Recovery area in S&D.
