HP8450 Printer No Longer Recognized by Windows

Update:10-11Source: network consolidation
Advertisement
Recently my PC became badly infected. Malwarebytes Antimalware and Spybot Search and Destroy now declare my PC virus free, but I have one artifact of the infection. Control panel as well as my software no longer sees my HP8450 printer. This problem first appeared when I was infected, this did not occur during or after cleaning. HP's online troubleshooter does not solve the problem. Further, I am unable to reinstall the printer; I have the original install CD and when prompted, Windows install wizard doesn't recognize the files on the CD. Trying a version of the software downloaded from HP's website, the install sees the device but cannot complete the install. I can't uninstall the printer because Control Panel doesn't recognize it as being installed. The printer is connected via USB cable and all of my other USB devices (mouse, keyboard, external hard drive) all work as they should. The printer was fully operational before the virus infections (Virtumonde.prx and Win32.TDSS.rtk).
I'm running XP SP2 on a Pentium 4 2.40Ghz CPU with 2GB RAM. I have cable internet, so I run a McAfee firewall.

I had the same problem after my computer got infected (And I am running McAfee with the firewall!).  The problem isn't your print driver, the problem is in your Windows operating system.  Try to reload or repair Windows from your backup disk (hope you have one).  It took three tries before i finally got the trojan eliminated and could reload Windows.
