I am a bit paranoid about downloading .exe files from unknown sources !?
CNET is NOT an unknown source Al. Where have you been all your (computer) life?
As I would assume you have an effective, up to date, AV and Firewall installed - what are you talking about anyway? CNET (download.com hosts hundreds of downloadable files from open source, shareware and commercial web companies and CNET surely you must have heard of?) is probably the biggest resource in the World for obtaining downloadable programmes from almost every source and EASUS is a highly reputable company.
The long standing reliable members of this forum (and meaning those, like myself, who are not anonymous - we have e-mail and website links in our profiles) are not in the business of giving false (and FREE, note!) advice, so go ahead and get your problems resolved via the advice and link given. Only ever query "advice" if given - on any forum - by anonymous members.
