I have some empty system folders created by a virus and whenever i try to delete it or remove it says it is a system folder and hence cannot delete it .so can somebody tell me how to remove it??

Where are the folders located???

Try doing the following:

Download Malwarebytes' Anti-Malware (http://www.download.com/Malwarebytes...=dl&tag=button) to your desktop.

* Double-click mbam-setup.exe and follow the prompts to install the program.
* At the end, be sure to checkmark the Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform full scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.
* When completed, a log will open in Notepad.
* Post the log back here.

Make sure that you restart the computer.

The log can also be found here:
C:\Documents and Settings\Username\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs\log-date.txt
Or at C:\Program Files\Malwarebytes' Anti-Malware\Logs\log-date.txt

What folders?
Xp pro or home?

If its pro just set the permissions so you have full control then take ownership of it, then you can delete easy

alternatively try safe mode as administrator user
