Strange File in My Documents folder.?

Question

hi, good day to all..

i am using windows xp sp2 on my internet cafe, i have 30 units.. my problem is, there is this "01.file" that is building up in almost every shared folder on my network.. this file ranging from, smallest 3 mb file to 2G, i am wondering where this come from, i tried opening it to different programs but to no avail.

i once opened a 3mb file to a notepad and it shows only huge amount spaces and a "hello world" word in the end..

at first i thought it was downloaded by clients but i realized that a 2G file cannot be downloaded in any of my client pc in a day because their bandwidth is limited and no client last that long online..

can u please help me with this one thanks

i am currently the admin of this cafe (technician) i tried scanning the infected PC but no result of any harm.. i have rollback RX installed to all my computer, and tried restoring all to a certain clean point but this file still appears on the network..

Talk to the Internet Cafe Admin, it may be legit OR it may be malware on their system.

You have a trojan. Get a trojan scanner and get rid of the infection.
