Chck the capacity of ur cpu and ram. U must hv atleast 2gb of cpu and 512mb ram or higher. If its not make sure tht u clean all cache files and fix all registry errors, difragg ur hdd/ide. Chk whether u r hdd is full; free u r hard disk, reduce the amount of visual effects on u r desktop and finally the main sypthom of worm virus is slowing down the speed of u r pc. Update u r antivirus and make a full of u r pc. It's better to install the latest antivirus software. While dng so reduce the number of autorun.exes at startup and only spared antivirus. Good luck.
