Currently having problems wit a number of systems that appear to be infected
with a New Unknown Virus – Symptoms as follows:

Scanning in “Safe Mode” with Current Virus Protection Software indicates a number of open Files and Folders - These open Files or Folders  frequently have the ASCI Chr 160 as the LAST DIGIT of the THREE DIGIT extension. – ( Tried using VET – INOCULATE and NORTON'S )

Attempts to Delete – Rename – Move or Copy all Fail (Due to Windows seeing them as  Open)

Attempts to Delete – Rename etc in the DOS MODE AFTER BOOTING with a Clean Boot Floppy Disk – Also Fail (Due to the limits of DOS)  - I believe DOS cannot read ASCI Characters above 132

Other Symptoms are:  

Multiplies when trying to Remove It:

Can affect both Files and Folders
Adds a Three Digit Character to the Folder Name the last Character as ACSI160  

None of these Re-Named files or Folders can be opened:

Unable to E-mail Due to Windows Seeing the File/Folder as Open:

Your Help Appreciated - Qbit

I have almost the same problem with some computer in a firm.
The symptoms are almost the same exluding the three digits.
Whan I whant to delete a file/folder the OS write that the folder or file is used by another application or user and that the deletation is not allowed.

In task manager I don't see nothing unusual and the performace of those machines are regular.

I think that some kind of application like Antivirus or realtime scan or something like this is going to indexing all the folders/files names and that is going to prevent the deletation.

Please can somebody give me an advice how to solve this problem?
