Yeah but after that Norton CR@P expired, then your computer went to $hit....
Save / Backup all your files and reload the OS, after that get
Firefox for a browser and never use Internet Explorer ever ever again.... IE is the worst and so venerable to virus's and spyware is sickening.. Firefox is a good browser and has lots of addons that make it even better. Like
AdBlock which stops all popups and spam and on page ads... great addon, one of thousands and thousands out for firefox...
After that go purchase and install NOD32 and start fresh... Never run without a good antivirus...
Its not worth messing around with a computer that is full of crap and trying to clean it.... backup stuff needed and just do a reload and be done with it... If you have the original OS that came with the computer.. If not, then go buy a copy of windows 7 and start fresh.... it'll be like a whole new computer...
