Good afternoon,

Yesterday, I noticed that my HDD light was flashing about twice a
second, every second, even while the computer was idle.

While I got to wondering, I decided to open Vista's Resource Monitor,
and I looked at the "Disk" section.

Sitting at the top, when sorted in Write >> ascending, sits Explorer.exe
writing to c:\users\[uname]\AppData\Local\Microsoft\usrclass.dat.

In third place sits rundll32.exe, writing to the same file.

I was just wondering what this file was, and why my computer continues
to write to the file, and how much damage this constant writing may do
to my hard drive.

Thank you,

answr to this please. :)

I have little doubt that your p. c. is infected.If you can use Windows
Update,update Windows Defender with the latest definitions and run a
complete system-wide full scan thoroughly.If you cannot,download the Windows
Malicious Software removal tool from the Microsoft download center from some
other machine where you can browse properly and run it locally on your
system.

Same problems... even worst... HDD temperature: 58 degrees. I'm running
Win Vista Ultimate 32bit, up-2-date. I have also another prb: When I
open my browser and I type an URL(I tried Mozilla, IE5, Opera), process
explorer.exe crashes, taskbar dissappears, and I have to reopen the
explorer manually. From time to time, this message appears:
'[image: [url]http://i140.photobucket.com/albums/r15/Mad_Dogu/pic1.jpg][/url]'
([url]http://i140.photobucket.com/albums/r15/Mad_Dogu/pic1.jpg[/url])

and I still receive messages like this one but from different sources
like WinAnonimously... :|

Any option I choose, this URL is opened :
