In a momentary lapse of sanity, I opened up an attachment (a .pdf) from an unknown email address (the domain doesn't seem to be a website) in the gmail app on my iPhone 5. Realizing that there was a reasonable probability that there was a Trojan, I quickly closed the file.
I now have the following related questions:
- Is there any chance I just put a virus on my iPhone?
- If so, what should I do to scan my phone and verify?
- In the future, is there a recommended way to scan such attachments as a precaution before opening them?
Looking at a number of questions on this website, I have learned that for my (non-jailbroken) phone, it is fairly unlikely that I got a virus, but I'd appreciate knowing that for sure.
