I noticed that SVCHOST.EXE in my task manager is increasing in size and writing 32KB per second to the hard disk. On the other hand, I noticed there are files of the format BIT????.tmp in my "Local Settings\temp" folder. These files are exactly 18,453 KB in length. Only the last one cannot be deleted and these files are getting created only when connecting to the internet. I am using dial up so there is no way 32KB/s is being downloaded from the internet. It's most occuring when I am using MSN Messenger but I tried killing MSN Messenger, ZoneAlarm and NOD32 and the files are still being created and not getting deleted.
