Not the virus one!

If I open up task manager and enable the I/O columns, this Lsass.exe keeps reading and writing onto my hard drive. What's causing this and is it normal? I have Windows xp SP2. I'm always been checking for viruses and spyware, so i'm positive some windows service is writing some logs or doing something! Am I the only one?!

I had a similar problem on a laptop at work. The user was having the internet sessions hang; seemingly going no where. Then the machine would get really slow for everything.

Take a closer look through the Task Manager Processes to see if you can find a Webassist. If you see it running after you've connected to the internet this may be what is happening.

The real problem for the machine referrenced above was Webassist which would start chewing up CPU time any time IE (internet) was started. You can end Webassist and Lsass will continue to chew away at the CPU time. Webassist is some spyware. You can run SpyBot (its freeware) and it may correct the problem. I finally just rebooted the machine, immediately went to webassist and renamed it something else. Poof, problem gone. There doesn't seem to be any issues without Webassist enabled and this user/machine doesn't need it for any programming, etc.
