...NOT SOLVED!!!
Nooooo, I spoke too soon. These xxxx-ing files just keep coming back. This mess is just driving me (even more) crazy! Now I have used about 5 different AV /anti-trojan scanners just to find out if I still have something on the computer - but they dont find anything.
What are these files? (Now its only one - called 00000649)
I delete them before I start a full system scan, then during the scan they will appear again, and cause NAV to crash. Are they placed by the AV-program, and if so why cant the program scan its own files? If there is still a trojan in my system, why doesnt any program find it?
Ive tried to replace ntdll.dll and the navw32.exe files from a healthy system - same thing! I sent a message to symantec about it - no answer!
As for formatting the whole deal, I cant do that right now - unfortunately I only have a quick restore cd and I have too much stuff that would be lost (too much to backup on cds)
Anyone, plz!
