i have just run a full scan with avast. 212 files cannot be scanned. the result said:
Unable to scan. Archive is password protected.

example of files that cant be scanned:
c:\...\allusers\application data\spybot - search and destroy\recovery\WindowsSecurityCenterAntivirusDisableNotify.zip\sbRecovery.ini

c:\...\allusers\application data\spybot - search and destroy\recovery\WindowsSecurityCenterAntivirusDisableNotify.zip\sbRecovery.reg

c:\......\Local Settings\temp\SHR_6_0_ENUS.tmp\shrins.ui\setcss.vbs
c:\......\Local Settings\temp\SHR_6_0_ENUS.tmp\shrins.ui\instxp.css
