I use my own sports betting database but needed to buy some info from a sports betting supplier not tips just sports betting info. Basically they send you a email daily with the daily sports info update which you download to your own database. My question is, is there a way to see if these emails are sent with any trojan or spyware?

The site supplies sports betting info to maybe about 25 sports bettors but I'm just thinking if the guy had the option to install a trojan or Keylogger to one of the best sports bettors and get that sports bettors info (where there's gambling and money involved people do weird things) etc. Would Malwarebytes or spybot or some others?

any info appreciated thanks.

No security is full-proof.
If you're that worried about it, but still want to accept the emails, you could only accept them on a secondary computer. Or at the least you could use a virtual machine (free) for reading them.
