My pc's been running really slow lately so i've bin removing files that have my daughters have been clogging it up with - i.e. napster and generally cleaning it up. Anyway i downloaded avg rootkit and it found something on system32/rundll.exe so i agreed to delete it. Now I can't open up certain performance programs like system or add/ remove programs saying windows cant find rundll - I know its my own fault but can anyone help me how to get it back? (I did system restore to a couple of days ago but that didn't work)
A lesson in why the average user shouldn't use such tools. Try running sfc /scannow (remember the space). If you dont have a Recovery Partition you will need your Windows CD.
