Windows 7 - How to delete a file in system32

Hi all,

I'm trying to delete a file in System32 folder. No matter what I did such as Right click, drop and drag, install Delete programm, I still cannot delete this virus file. Could you please show me how to delete that file pls. Thanks.

Hi, titi2.
What is the exact name of the file and what extension (.exe, .bat, .dll, ect.)?

The name is RDVGHELPER. I believe it is an .exe file but in system32, it doesn't have .exe. Thanks and can you help me delete this file pls.

As there seems to be little info to be gleaned from the web regarding this software, please download AutoRuns. Right-click the .zip file and select Extract All.... Right-click the autoruns.exe file and select Run as Adminitrator. When the window reports Ready in the bottom left corner, click on File in top left corner and select Save > Save.

I will try to help out the best I can.
How long has this been going on and any and all information you can provide as to the source of this infection would be a great help in trying to remedy the issue.

I suggest you install a small free program named Unlocker (Download Unlocker 1.9.1 - FileHippo.com) and take its help to delete the file. I am sure it shall succeed in deleting it.

The RDVGHelper.exe file can be a legitimate system file or a disguised threat to the computer as it is very easy for malicious threats to disguise themselves as something else. I wouldn't delete the file unless you are sure it has been infected. Run MBAM (MalwareBytesAntiMalware), free version, which will scan your system and identify any potential threats. Please post back your results.

I was going to suggest this, but thought it wise to verify the legitamacy of the file in question first.
Unlocker will dispose of troublesome files/folders.

Unlocker doesn't actually dispose of or remove a file; it removes the "restriction" that is locking the file which will permit removal. Submitted strictly for clarification.

Just checked on my system, and I don't have this file installed. Checking on the web reveals it to be malware, specifically adware and possibly a worm.

Be careful how you reply to a post. Just because a file, any file, isn't located on your system does not mean it is malicious; ie, virus, worm, malware, adware or the like. The file "rdvghelper" is reported by "PcSafeDoctor" as follows;

"The RDVGHelper.exe file can be a legitimate system file or a disguised threat to the computer as it is very easy for malicious threats to disguise themselves as genuine RDVGHelper.exe file and cause harm to your system. Once the RDVGHelper.exe is infected, it will wantonly attack your computer; delete necessary system files without letting you know, making the computer run improperly."

As I have already suggested to the OP, running MBAM will help in determing whether or not the file is infected.
