Hey Hey guys i have an NEC Versa laptop it seems everytime i get online my mcaffee anti virus blocks some sort of trogan or i get buffer overflow warning coming up on my laptop.

I can easily get 3-4 a night whilst connected to broadband, but not actually even have explorer or mozilla open or running - ie I am not actively online looking at any sites.

My missus computer which is also connected to the same broadband line, does not get any attacks/warnings at all, we both use same antivirus software.....  can my laptop already be infected with something that is making it more susceptable to trojans etc?

I regularly use Ad-aware and Spybot , and it usually finds 7 or so files with spyware, and again without even getting online at all, run both programs again, and still find more spyware after previously deleting them the day before

I am fed up with all the crap im going through and am going to re format my harddrive wat is the best way for me to do this ie do I use safe mode etc etc?
thanks alot
