symantec uncomplete removal

My PC is 4 years old and apparently there's some left over symantec stuff and it doesn't show on Start>All Programs. But the folder is still in C:\Program files. Is it safe to just delete the folders or some removal tools are needed in this case? I have AVG and the system has been running fairly well until the last few days. BSOD and hanging at shutdown. Someone suggest it might be the symantec and AVG conflict.

Thanks!

 

If you uninstalled Symantec, Just delete the folders.

You might have a few Norton things going on in the registry. Deleting the system folder may kill that, but it cannot hurt to run the Norton removal tool for the software that came with your PC.

However, I doubt that any conflict would wait til now to show up.
