Virus hidden in restore folder in XP ..... how to remove

By Dusterman ·
Found massive infection removed , only to find that it was also in the system restore :-(
Loaded new [ older ] hard drive and rebooted the machine with the original as a slave .....can access all pertanent info .... all is good [ may be ok ? ].
Works great ......... but can't stand to be beaten ....... any info about cleaning out the restore folder will be appreciated .
Thought about trying to delete the infected folder and replace it with the "new" one ....but in case it's needed it would only have the very basics and no old "important" info.
Thank you in advance .

Deletes All Data?

by PC_Techie, MCP In reply to Disable system restore

When system restore is turned off, it doesn't delete all data on the computer, just the system restore points. It will not delete data like important files, programs, etc.

System Restore does not monitor changes to or recover personal data files such as Word documents, graphics, e-mail, etc.

As System Restore monitors a core set of specified system and application file types, any downloaded or saved file which has an extension type monitored by System Restore (e.g. .exe, .dlls) and stored on a monitored drive will be lost if restoring to a point prior to the download or save. If you do not want to lose files with a monitored extension due to a restore, you should move these files to the My Documents folder or to a non-monitored partition not restored during a restore process. If you have unknowingly deleted some files due to a restore on your system, you can always recover them by undoing the restore process in question.

Possible solution for your situation!

by bijoy.y In reply to Virus hidden in restore f ...

We have been witnessing some strange incidents on some of the desktops of the users here at the Malad, Mumbai site.
It is strange enough that our corporate antivirus is not able to find any of the worms, trojan variants and cloaked malwares
such as this case.
I have put down some of my findings here for your perusal which could be of some use as a reference by the time our antivirus
team comes up with a possible solution or a patch for this existing situation.


1) User not able to access web pages.
2) Antivirus definitions too old on systems infected and are not able to detect any viruses.
3) Sytem processing very slowly.
4) DNS address changes.


1) Strange hidden folders like "SYSTEM"; "RESTORE" and a file named "autorun.ini" are found in all the drive
partitions present in the PC. On deletion of the abovementioned folders and files, they have been noticed to
regenerate in a fraction of a second.

2) On isolating the autorun.ini file, it showed reference to an exe within the restore folder called RanDll.exe
which is triggered to execute when the user double-clicks the drive to access his/her files.
Following is a sample of the malicious code found within the autorun.ini file.
action=Open folder to view files

3) On zeroing on the RanDll.exe file, it was found to be responsible for all the unusual activities on the system.
Also please find attached a report received after submitting the file to .


Step 1> Disable system Restore on all Drives.
Step 2> Disconnect Lan Cable
Step 3> Reboot system into Safe Mode.
Step 4> Go into the registry editor. Take backup of the registry and search for the file named "randll.exe".
Delete all entries found from the registry.
Step 5> Delete all the hidden "RESTORE" folders from all the drive partition and the "autorun.ini" files
carefully using the Windows Explorer (Winkey+E). For a change, we did not find the folder options getting disabled here.
Step 6> Reboot the system to normal mode.
Step 7> Re-connect the LAN cable.
Step 8> Update your antivirus to the latest definitions and scan your system.
Update antispyware to the latest definitions and scan ur system thoroughly.

No less than 31 months ago, this thread was put to rest. Then two and a half years later, you come along and dig it all up again.

While that may work

I think you'll find you are about 4 years too late. This question was asked in 2006.

I very much doubt that the OP still wants an answer.
