Avast did System Restore and deleted a system file

system · 2014-07-11T14:08:39.000Z

I am missing NTDLL.dll file. Cannot open Windows IE.

Can use Chrome and Firefox and computer, but I was told this is a CRITICAL FILE for windows and to do a system restore via Windows.

Using Windows 7, started to do a restore and noticed that on JULY 5 AVAST free created a system restore point, which is When my Problems began.

How can I REMOVE the restore point that AVAST created?

See if this solves it:
start > run > sfc /scannow

Thanx, I tried that and it did not solve the problem

I just went to system tools/internet explorer add ons, it said None,
so I attempted to open it again and it is now functioning, for whatever reason
