I get this message from my F-secure antivirus that

Malicious code found in file c:\system volum
information\_restore{_RESTORE{50E2DE13-ED86-404F-8C83-A1378B7CD1EA}\RP493\A0050784.EXE.
Infection: Trojan-Downloader.Win32.IstBar.is
Action: failed.

I am an administrator but still when I try to open system volum
information catalog it says: access is denied

I could not find any information about this virus on the net. Now I can
probably ask F-secure to delete the virus, but I still don't know what
it is and whay I can not get into system volum information catalogue

Right click My Computer, Properties, System Restore. Turn it off, turn it back on. Your system restore point cache will be flushed.

Follow the advice of Doug Knox then perform the following...


Dump the contents of the IE Temporary Internet Folder cache (TIF)
Start --> Settings --> Control Panel --> Internet Options --> Delete Files

Dump the contents of the Mozilla FireFox Cache { if you use FireFox }
Tools --> Options --> Privacy --> Cache --> Clear


Download CLEAN.EXE from the URL --
http://www.ik-cs.com/programs/virtools/clean.exe

It is a self-extracting ZIP file that contains the Kixtart Script Interpreter
{ http://kixtart.org Kixtart is CareWare } three batch files, two Kixtart scripts, two Link
(.lnk) files and a PDF instruction file.

GETFILES.BAT -- For downloading (FTP) the files needed to run the McAfee Command Line
Scanner. If you are using Windows XP, you may have to disable the Windows XP FireWall to
allow the FTP utility to download the needed files

CLEAN.BAT -- For running within Windows after running c:\mcafee\GetFiles.BAT. If you choose
to scan again at a future date, run this batch file. It will automatically check the date
of the McAfee DAT files and if it is a couple of days old, it will download (FTP) the latest
signature files and install them before performing the scan.

DOSCLEAN.BAT -- For use on a Win9x/ME PC or on a Win2K/WinXP PC that is using FAT32 after
you have booted from an Emergency Boot Disk or DOS disk and have already executed;
c:\mcafee\GetFiles.BAT from within Windows. DOS disk boot images can be obtained from;
http://www.bootdisk.com/bootdisk.htm

I need you to perform the following...

Execute; CLEAN.EXE
Choose; Unzip
Choose; Close

Execute; c:\mcafee\GetFiles.BAT
{ or Double-click on 'GetFiles Link' in c:\mcafee }

Reboot the PC into Safe Mode [F8 key during boot]

Shutdown as many applications as possible !
It would also help for you to read - "How to perform a clean boot in Windows XP"
http://support.microsoft.com/kb/310353

Execute; c:\mcafee\CLEAN.BAT
{ or Double-click on 'Clean Link' in c:\mcafee }

A final report in HTML format called C:\mcafee\ScanReport.HTML will be generated. At the
end of the scan, it will be displayed in your browser (Opera, FireFox or Internet Explorer).
It is suggested that you move the report out of c:\mcafee before performing another scan.
It would be a good idea to scan in Safe Mode and in Normal Mode and save a copy of the HTML
report for each session.

System Volume Information is inaccessible as a normal user in
Explorer.

Is it only being found in System Volume Information?

If so, disable System Restore, then reboot. Rescan your system to see
if it has disappeared. Sometimes anti-virus programs canít get rid of
them. Try Spyware Doctor if it hasnít gone after rebooting.

When itís gone, re-enable System Restore.
