A few months ago bandwidth I noticed bandwidth usage on my mobile hot spot skyrocketed.  Typical bandwidth for the prior year was an average of 5-6G per month. Usage soared to 10G per month, often climbing 4G per weekend. Since active streaming is rarely used (audios, podcasts, movies, etc) the jump is a mystery.  Both the hot spot and computer are always in my possession eliminating someone using either without my knowledge. Most recently, usage skyrocketed to nearly 20G.  Needless to say, the bandwidth usage charges are killing me. I'm assuming I've been hijacked somehow but am unable to pin down the reason.

Check out the info in the link below for securing your portable hot spot.

Buddy215 - thanks for the tips on securing the hot spot. Thinking the same thing, I used my wife's computer instead of mine on the hotspot.  The bandwidth usage was normal.  I'm convinced the problem is in my computer and not the hot spot itself. To be doubly certain, I'll take the security steps you referred me to then test bandwidth using my computer and hers.

 

I appreciate the fast response.

 

Martin

If it turns out to be your computer then you should look for programs such as Bit Torrent....P2Ps.

 

Could be malware using your computer to serve spam or part of a botnet.

It is definitely something in my computer. How do I chase down and destroy bit torrents, p2p and other viruses plaguing me? BTW: Took your advice and hardened my hot spot. Appreciate that tip.

Those should show up in your add/ remove list.

 

You can post a new topic in Virus, Trojan, Spyware, and Malware Removal Logs after following the

instructions for creating a DDS log in instruction #6 found here: Preparation Guide For Use Before Using Malware Removal Tools and Requesting Help

 

Once you have posted the new topic do not bump it until one of the members there has responded.

Not sure how long that could be....could be days. If your computer has malware on it those specialists who volunteer their

services in that forum will find it.
