For the past couple of months I've been dealingarrow-10x10.png with random programsarrow-10x10.png installingarrow-10x10.png themselves on my laptoparrow-10x10.png and the command prompt opening itself and then closing again, especially when I leave the comp open and running. Usually I find the programsarrow-10x10.png in Control Panel and uninstall them from there, then run Malwarebytesarrow-10x10.png, but in this case I'm finding nothing that works. I've run Malwarebytesarrow-10x10.png, AdwCleanerarrow-10x10.png, the Junk Removal Toolarrow-10x10.png, Wipe, and eScan, as well as CC Cleanerarrow-10x10.png. My temp files and internet cache are good and clean now, but the problem still persists after multiple restartsarrow-10x10.png.

 

I am seeing the pop-up ads as shown in the screen cap, especially on forum-based websites like bleepingcomputer (Facebook and similar sites do not seem to be effected). Random tabs open and redirect as well, and the browser is running EXTREMELY slowly.

 

At first I thought it was only a problem with Firefox (my default browser), but when I opened up Chrome the same results and popups came back. Thinking I'd be sneaky, I downloadedarrow-10x10.png and ran Opera, only to have the same issues.

 

I run a photography business, so my laptoparrow-10x10.png is basically my lifeblood and money-maker. Please help if you can! 

 

Many thanksarrow-10x10.png,

 

Danielle

Going to try this right now, thankarrow-10x10.png you!

 

Additionally I found this tidbit: https://thecomputerperson.wordpress.com/2015/08/19/the-mystery-of-82-163-143-172-and-82-163-142-174/ Sure enough, upon checkingarrow-10x10.png my DNS settings, they were changed to that erroneous server (see screencap). I've reverted it back to derfault, and am now going to go follow your fix. Will report back soon.
