Internet Explorer stopped working

[DLambie]

Is it possible to reinstall Internet Explorer, I opened firefox to post this, as it was working last knight and this morning it will not open at all plus I get an error of can not find sshnas21.dll so unsure what this file is.

The file you are referring to is part of the Trojan fakealert virus run your antivirus program.
