if this has never happend to you how would you know this to be the case? "Probably you're just being pinged. Happens automatically, for a variety of reasons, and has nothing to do with IHub."
Yes, you have. You just didn't know it unless you have R/T monitoring set up to tell you.
Recently iHub has been getting hit with a particular trojan, the HTML/Infected.WebPage.Gen - Malware (Trojan), which may be used to perform malicious activities on your computer and possibly download additional malware.
BTW, since you're Mac, you're still vulnerable.
Probably you're just being pinged.
Nope. Good Windows online scanner: http://windowsecurity.com/ > Security Tests > Trojan Scan > Select Deep Scan (and go walk the dog).
