and i'll try what you said neieus , hope will work.......and the free trile was just for 30 days not a year.....will try and will get back to you and let you know what happened
by all means,before installing an antivirus,read the reviews and comparisons. avast is free,registration is free.i highly recommend it.bit defender ranks highest if you dont want to deal with antivirus programs.
