I can comment first hand on this.
Since June and on three separate occasions, our Internet service was suspended by Rogers - they reported a SpyBot on one of our home computers that was generating DDoS attacks. Anti-virus and all malware scans always ran clean. After the latest suspension, Rogers reported that AVG was the culprit. We have AVG Internet Security 8.5. I reported this to AVG around two weeks ago and this was escalated in both organizations. Today I received notification that the problem was now addressed entirely. And, you can use all the AVG anti-spam functions - you do not need to turn anything off.
AVG ordinarily runs fine on all our computers and their support staff and management have been exceptional and proactive in diagnosing the problem.
This is a brief explanation from a senior AVG person: In very short, the reason was the way how the Mailshell component checks for spam (using a reputation service) that also triggered some security checks on the Rogers side.
If your account has been suspended, and your problem is identical to ours, then call the Security department at Rogers. They should be aware of this now. If your problem persists, add a reply and I'll look in occasionally. I found your post and subscribed after Googling the keywords today.
Hope that helps.
