Cupertinians have now started to remove anti-virus and anti-malware apps from their App Store, or at least that's how it seems. Intego, developer of VirusBarrier, reports that Apple took down its app under the premise that it had a misleading description. An attempt to re-upload the product, with a different, much clearer description, was also blocked.
According to Intego, this has happened to a few other companies, which supply anti-virus solutions to the App Store. Apparently, Apple does not want users believing that iOS 8 may have any exploitable flaws. Unfortunately, Intego's VirusBarrier was an app, which actually scans emails and cloud files, not the iOS device itself, so it was useful for its own niche of users, who understood what the app is for.
VirusBarrier will continue to get updates, Intego says, so as long as you have it on your device, you're fine. If you need to delete it or perform a factory reset, you will lose the app.
