After installation, my computer locks up. It freezes on startup. What happened? (Norton Symantec error)
This error is caused by installing ESET NOD32 antivirus or ESET Smart Security onto a computer that already has Symantec Norton Antivirus on it. On a rare occasion, it can be cause by installing version 3 over version 2.7 without uninstallion version 2.7 first.
THE EXPLANATION:
An antivirus program is, by its nature, looking for something else on the computer that fits the following criteria.
1. May change computer's data.
2. Activates without user's knowledge.
3. Connects to internet frequently.
This describes most viruses, but it also describes most antivirus programs as well. When you have two antivirus programs on the computer, they check each other for these criteria, and occasionally mis-label each other as a virus. This can cause a lockup, as can the heavy use of your computer by two different antivirus programs.
THE FIX
1. Put your computer into safe mode. You can read about how to do that at either of the following two links.

http://en.wikipedia.org/wiki/Safe_mode
2. Uninstall NOD32 by going into Start, All Programs, ESET, and then selecting Uninstall.
3. Next, click Start, go to the Control Panel, and select Add or Remove Programs. Browse through this list for any references to Symantec or Norton, then click Change / Remove. Uninstall these files.
4. Now to may restart the computer normally.
5. You will need to make certain Norton is entirely off your computer - to do this, please use Norton's official removal tool, found at
http://service1.symantec.com/SUPPORT/tsgeninfo.nsf/docid/2005033108162039
It will ask you what version of Norton you have - this is irrelevant, as the download tool is the same regardless of which option you select.
6. You may now safely re-download ESET NOD32 antivirus or ESET Smart Security. Visit our download site at
