I don't have broadband, so I tend to use my cellphone as a portable WiFi hotspot, and let my laptop use it's data connection. This means that I tend to keep a close eye on how much data that it uses, and I've got a fairly good idea of what does what, and how much this or that use.
Yesterday, I had my laptop sitting, connected but not doing anything, and left it for a couple of hours. I know for a fact that it wasn't streaming anything, or downloading anything, or anything like that, and when I came back, I saw that it had chewed through over 2 gigs worth of data inside that time, which for what I was doing (almost nothing) should have been impossible.
Under WiFi Performance, in my task manger, I noticed that the the kbs per second was spiking as high as 7-8 mbs or more, and balancer, which I downloaded to try and control it (which was like banging my head against a brick wall, by the way) told me that my browser had as many as 30 different connections open at once, which seriously strikes me as iffy, to say the least.
Malwarebytes picked up nothing, when I scanned it, which is all the more frustrating. I was running Avast Antivirus, which I notices seemed to be doing something that it should, in terms of data sent/received as well, so I initially though that it might have been this causing the problem. I swapped that out, going back to AVG (which I changed out in the first place because of the way that watchdog sinks it's teeth into my external hard drive, and ran a scan which picked up a few things, (.js files) which it told me could be adware related?
However, I'm still noticing what seem to be unusually high WiFi usage spikes. (300+ kbps) even after performing a refresh on the laptop itself, changing my browser (I was using Torch, and I'm now using Opera) and setting the wifi connection as metered.
Do I have a virus, or am I just being paranoid, now? Or Could something else be going on? Please help.
I'm seriously considering doing a Factory Restore on my laptop, now. It should also be noted that my laptop has no c.d drive, came with windows 8.1 preintalled (so without disks) and that as you've probably gathered, my Internet, in terms of how much data I can use is very, very limited. My funds are next to non-existant, too, which doesn't help matters.
I usually wouldn't go over 500 megs of data in a day, (and more often than not, it's under 300 megs) and that's when I'm actively downloading things, not just sitting idle on a page. So to use 2.2 gigs, in about 2 hours, seems well over the line.
