After getting the latest XP auto update on Sat,all was well except one of the updates would not install.
So off I whent to the main MS update page to see what I could do.........the update page would not load,giving me a error code.
So I searched the error code and found nothing related to my problem,but suggestions to check my PC with the Symantic on line virus and trojan checker.
So I did (let run overnight) and it found a trojan called "killAV" which tries to shut down your antivirus prog(it didnt,but its on my PC and its gotta go)
Now my A/V program updates daily as does the MS spyware prog so I dont know how I got it(and I run them...no good updating if you dont run the progs)
But my point is...even if you are carefull,and I am,they can still get you
I would suggest you add the above link to your favorites folder and run it when you get time(its a long job)
Anyway I followed a link on how to rid myself of the nasty and it said to "disable System Restore and boot into safe mode,via msconfig"
DONT DO IT THAT WAY as my PC would not boot past the XP splash screen ,and just kept resetting
NEVER USE msconfig to set your PC to boot to safe mode...use the "F#" button(a lot of different combinations for different PCs..mine is F2) that way you do-not lock your PC on a dead cycle,you can allways boot normally
The only way I could stop that rebooting cycle was to reformat and reinstall
As I said I am careful and was up and running within the hour....but its still a pain in the
