I have Windows 7 home 64bit and I use the 2012 version of Norton Internet Security on a new pc. After a few weeks of running fine I ran into this problem: After start up I clicked on my norton desktop icon and nothing happened I waited about a minute for it to load then tryed to load it from the start bar and again nothing happened. I did have a icon next to my clock so I tryed clicking that and yet again nothing happened. I went to restart my pc and windows brought up the thing that it uses to force close a program when turning off the pc. After restart I clicked it and it loaded instantly like it normally would I did a live update and did a full scan with nothing found but some cookies. Iv had norton installed for a few weeks before this problem happened and after restart it seems to be working. Was this a virus that caused this? Or something wrong with windows? Iv never had this happen before and iv used norton for years. A bit worried, thanks in advance for any help.
