You always take a chance but if you have a good antivirus which is up to date continu your download and once finished scan it with your security. Most of the time it's Spyware which infiltrates the system. Get a spyware detection program. Most of the time they're just cookies then find them in your Cookie folder and delete them. Voila !!!! and your file should be just perfect . I know it's scarry at first . See ya!
