When this machine was turned off last night, I had 61GB of freespace. The HDD was clean. No virus with latest updates with AVG. CCleaner had removed all temp files. Defraggler had been run 7 times and I had got the fragmented files down to a measely 1.5Gb and 1 file.

I am at a loss to understand how, when my friend started his computer this morning, that the HDD is obliterated with a 60GB fragmented file. Namely, Windows\system32\jcsb.DAT.


Please can someone help me with this. I am at the point where it would seem I have to Format the harddrive and start from scratch. Has anyone got some clues to help me sort this please?

:thumbsup:

Hi -

Have you run Malwarebytes and SUPERAntiSpyware - This can be the result of a Rouge Infection still in your system -
Your AVG "may" detect it but, most likely, will not remove it -

Thank You - :thumbsup:

In your last post HERE you said you were removing Windows\system32\jcsb.DAT ?? -
This may have also caused a problem -
Please Add to your topics rather than start a new one if they are related - It can confuse the helpers and they do not have the back ground on the problem that is ongoing

Thank You -

Edited last post in this thread to add this topic as a continuation. If this needs to be merged I can do the clean up and merge to keep it all together.

Lets see if the member comes back with malware in the scans before determining which forum.

Hi guys, started a new thread, because, I had thought the original matter had been resolved, and as I got through each additional problem item, started a new topic because I believed that was what was expected of me by rules of forums. I'm happy to place my topics/continue topics as directed, but appreciate some help developing appropriate habits of forum use. I am new to this. So, thanks for your patience.

Having downloaded and installed both suggested programs, run them, and both concluded no infection.

I rebooted the computer, and now the jcsb.dat file is only 57kb, and the previously 61GB mass fragmentation has disappeared, and the hard drive is now showing nly 1.7GB of fragmentation.

I'm now deeply frustrated.

What on earth could cause this random happening. Please note. The network connections are always disabled prior to shutdown. The internet connection is via a Thomson wireless ADSL router supplied by the ISP. On start up I have carefully ensured only 40 odd processes start.

Just ran defraggler again. The result says, 1 fragmented file of 1.5GB. Total fragments 620. And 11% fragmentation. Which is what was shown before I shut down last night. Under the File List Tab, top item is Filename = pagefile.sys; fragments = 620; Size 1,572,068 KB. There are other files listed below this but obviously too small to be registered on the main window

Sorry, yes, I mentioned that in my second most recent post. Ran both antimalware programs as suggested which found no infections, except 15 tracking cookies which I remoed.
