The program can't start because USP10.dll is missing from your computer

All of a sudden this error message pops up on practically anything I try and open on my computer. Windows 7 dell about 1 1/2 yrs old. Don't remember the specifics, and this error prevents me from looking it up on the computer. Cannot access internet, install new programs, etc. I tried putting this file on a jump drive from my laptop, only to discover the file is still in c\windows\system32. So my assumption is virus, as a lot of the features in the system and security section of control panel will not work. Has anyone else encountered this? I also tried sfc /scannow and it stopped after 6 %. Any suggestions aside from re- formatting?

Hi,

Did you make any changes to the computer prior to the issue?

Method 1
I would suggest you to perform clean boot and then try to perform SFC scan. When you perform clean boot make sure you also disable all the antivirus and firewall on the computer.

Note:
Microsoft does not recommend that you turn off antivirus protection under most conditions. Turn off antivirus protection only temporarily to restore a computer. Follow step 7 from the clean boot article KB929135 to reset the computer to normal mode.

Method 2

I would suggest you to run online virus scan using Microsoft safety scanner to check if your computer is affected by virus.

Note:
When you perform online virus scan you will lose some data that is affected by virus. Microsoft is not responsible for such data loss.
