Hi I am new here. Just spent about 10 minutes writing up this thread, then deleted the text and restarted lol. To the main point: my WS2003EE with SP1 got infected, for the first time ever, by a trojan/spyware. Anti spyware didnt pick it up unfortunatly, even though i ran an update earlier. My router firewall seemed to have not responded for some reason - whatever. I got hit bad. I didnt wanna have to format and re-install as I have alot of stuff on there, programs, documents, projects, other backups - you name it. Tried several ways of removing it, couldnt. I then got Norton Corporate anti virus 10.0, installed perfect, picked up the devil and removed it. cool, was on the role! However the virus still existed some place, even after removing it and following instructions from symantecs website on where it would place it self etc.. The virus infected explorer.exe - not a good thing of course. so, ended up formatting and re-installing. The 2nd thing I decided to do was to install NAV Corp 10.0 after installing anti spyware, and no drivers (the only drivers left were to update the gfx card and capture card). NAV failed to install. I thought ok, perhaps I need to install the rest of the drivers, and software and the system will be updated etc... (after installing updates) and it would all be well. nope. I tried re-doing the installation of NAV Corp v10.0 - still failed. Was really getting annoyed. Did everything I could think of, but it still failed to install and still is failing. I googled the issue but there was no set cure. Been on symantec's website - any suggestions posted did not help. I do not understand what the problem is! Norton Anti Virus Corp edition v10.0 installed fine when i had been infected but not after reformatting and re-installing the computer. I do not understand. I looked at the event logs and found this: The description for Event ID ( 7 ) in Source ( Symantec AntiVirus ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. The description for Event ID ( 14 ) in Source ( Symantec AntiVirus ) cannot be found.

The description for Event ID ( 13 ) in Source ( Symantec AntiVirus ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. Also just found a new one: Product: Symantec AntiVirus -- Installation operation failed. well duh! lol. I dont know what the problem is! Does anyone know? I am really stuck and would really want to install this. if anyone has any suggestions or a solution, please post. Would greatly appreciate it! I am usually pretty darn good at this stuff but cannot figure out what the problem is. The virus is completly removed as I had scanned it on another OS on a different computer.
