Thanks for the incredibly fast reply! I understand that the number of temporary files varies. However, the difference is high, by 6,000 or more files. Thats why I was wondering. And manually I havent cleared the temporary files section in the last 3 weeks. Also I went throught my logs of the last months (I did a scan about every month, always however with version 1.46) and the number of files checked always slightly increased, never decreased to such an extent as it did yesterday. Perhaps I worry too much, but I hope it's alright to bother you guys. Thanks again!
