Technical Details

When NewEXE files are executed or copied, Harry infects them. It writes itself to the end of the file and modifies the NewEXE header to take control when infected file is executed.

Harry activates every time an infected file is executed. It changes the mouse cursor to an injection needle (syringe).

The virus contains these texts which are never displayed:

 F... Harry by Quantum / VLAD    \Control Panel\Cursors    Arrow  

Harry contains bugs and frequently crashes the infected machine.

Variant:Anxiety.A (W95/Anxiety)

This virus infects Windows 95 EXE files and is very similar to Harry. It does not change the mouse cursor.

The a variant contains this text which is never displayed:

Anxiety.Poppy.95 by VicodinES  


This variant is like Anxiety.A, but contains this text:

Anxiety.Poppy.II by VicodinES...feel the pain, mine not yours!         all alone and I don't understand         a cry for help and no one answers         will I last for more than a week         will I taste the gunpowder         can I end it all and make it easy         is it sick to ask         is it safe to cry         will I be gone soon         will I last         will you care         will I?         --         if you don't hear from me in a while -         say a prayer for me because I have left, never to return.         --         peaceful goodnight, hopefully...         Vic  

The Anxiety viruses are known to be in the wild. They do nothing significant in addition to replicating.
