which is crane lift planning software free to download?
for spyware - download spybot 2008 (free n easy) for virus protection - download 'avast antivirus' (free n relatively easy) - both r good programs, just be careful with spybot - it is v. powerful, but luckily u can choose what to delete after it finds possible bad files, just dont let it delete any registry files (C/WINDOWS/System32) - these are important files - leave them alone unless problems persist - then get professional advice.
