if infected na ur laptop
almost 100% it will be no use installing an antivirus
ma-virusan man gani ang naa nay antivurs software..
first, if naa u another PC..
download ComboFix.
burn in cd, then ran it sa ur laptop in a CD, do not copy it to ur laptop as most exes will infected as soon as executed or copied.
then yes lang ng yes..let it restart if it needs to..
then usa pa ka mag install ug Avira Free2012
update avira, then configure avira , expert mode.set it to High Detection, set it to repair then delete if fail to repair
use admin deep scan
