You have exceeded your profile space!
Came across an interesting issue today while cleaning a Malware infection from a client computer. Once I had cleaned the system up enough to load Windows XP in normal mode, I noticed a strange icon in the system tray. It was a large red circle with a white X, and when the mouse was hovered over the icon the message “Warning! You have exceeded your profile space by XXX KB” was displayed. Opening the program displayed a more detailed message:

Profile Storage Space
You have exceeded your profile storage space. Before you can log off, you need to move some items from your profile to network or local storage
This was on a computer that is not attached to a domain, with no quotas enabled by the administrator.
It seems that the Malware infection implemented a local security policy on the PC restricting the users profile storage space. Manually deleting unneeded files from My Documents to reduce the size of the profile had no affect.
Luckily I came across this registry modification that removed the quota and corrected the problem.
Take this code and paste it into notepad. Save the file as quotarem.reg (make sure to save as type All Files to avoid the .TXT extension) and then double click on it to merge the changes into your Windows registry.
Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System] "EnableProfileQuota"=- "ProfileQuotaMessage"=- "MaxProfileSize"=- "IncludeRegInProQuota"=- "WarnUser"=- "WarnUserTimeout"=-

Thank the man above for your fix!! I have paid “so called ON-LINE Geeks” to solve this problem, with NO results and money down the drain. I could not turn my computer off except by the power button. It all occurred when I used my Microsoft disk to re-install the operating system. What I did with your fix was go to Regedit and follow the first line of your fix [HKEY_CURRENT_USER ——————— ] . After the reg. data string ended and to the right of “SYSTEM” was an odd looking icon followed by EnableProfileQuota REG_Dword 0X00000000(1) . I changed the (1) to (0) and low and behold the red X in my system tray on the desktop went away and my shutdown is now back to normal. “THANK YOU, THANK YOU, THANK YOU !!!!!!!!! AND THANK YOU for your FREE professional advise .

Tried all the above to no avail. the file quotarem.reg edited with no flaws. but it did not stop the problem.
I solved it my self.
I edited the registry and removed all proquota.exe entries.
Then I rebooted into safe mode and removed all proquota.exe files and all is well.
Thanks
