I checked the website, and I got it too. On further investigation, it seems like it could be coming from another website
geoloc1 which is embedded there for generating location map for visitors. I checked geoloc1 on virustotal.com it says 1 malware on several of its pages.

As for the time differences, they must be because they all are using different calculation techniques. For moonsighting.com, they have explained their calculations here:

For others, they mostly use one of the standard methods, either Muslim World League or Umm Al-Qura. There are some other methods as well.
Because all these websites depend on mathematical calculations, it is not easy to say which is more accurate for each location. The time changes with location as well as latitude. Most of them take both these parameters into account but you can still not be 100% sure whether the calculation is 100% right.
The best method to find out which is correct is to actually find out prayer times by observing the sun.
To be on the safe side, for starting time of prayer, always use the last time and for end time of prayer, use the earliest time. That way you will be sure that you have prayed within the correct time period.
For example, if starting time for Fajr is mentioned as 5:07, 5:10 and 5:12 on different sites, then choose 5:12 as that is the last time starting. And for end time of Fajr (sunrise) if they say it is at 6:36, 6:38 and 6:42 then choose 6:36 as the end time and pray within 5:12 to 6:36.
Whenever you pray at the Masjid, then simply follow the time of the Masjid itself, as long as they not extremely off time limits.
