Remove malware step 7 -- Check for software corruption or hardware problem

Make sure you check for software corruption or hardware problems when trying to remove malware. Learn how in this part of our step-by-step guide for value-added resellers (VARs), systems integrators (SIs) and security consultants.

You may have software corruption or a hardware problem rather than a malware infection. Try reinstalling Windows or your affected application(s). If that doesn't work, try to recall any recent hardware changes you've made such as adding memory, a video card, etc. You could have some bad memory, a poorly-seated PCI card, or other issue that could take forever to figure out unless you get your hands dirty troubleshooting at that level or having it looked at by a qualified technician.
