Windows 7 Ultimate SP1, 4 GB, Intel Core 2 1.83 GHz

After a 22 minute scan, Spybot found about 60 cookies.
When I clicked 'Fix selected' is hung ("Not responding").
I saw some constant disk activity and I waited for 15 minutes that stopped when I terminated the program.
I restarted Spybot and after it finished rescanning, the 60 cookies were gone.
