Windows cannot find regsvr.exe. Make sure you typed the name corretly

i got an error poped up as "Windows cannot find regsvr.exe. Make sure you typed the name corretly , and then try again. To search for a file, click the start button,and then click search"

Its from a virus which is most probably removed by your antivirus program but its refrence is still there. You are required to delete its refrence from msconfig.

Start --> RUN
type 'msconfig"
Goto Startup and uncheck unwanted items

Now reboot and should work , if it doesnt then let me know.

Also if possible find the same file on google.. download tht windows for you Os wich correct version.. also take backup of old file.. then replace it with new file.. reboot the comp.. and see if the error repeats..
