|Trojan -- White Screen of Internet Connection – Windows 7 – Problem & Solution|
A Trojan Hijacked my Wifi Network connection and my LAN wired internet connection causing a white screen upon connection. I have resolved this problem after many hours of work and research. Hope this write-up helps you save time!
On computer boot WHITE SCREEN of death appeared. A puzzling internet message about the requested page being unable to load / retry option visible.
But the white screen had no tool bars, no options, would not minimize, no right click functions. The windows key made the main windows bar appear but I could not switch to any other screens or programs, they would open behind the white screen.
Accidently, I discovered that if I booted with the wifi antenna OFF I had a functional computer but if I turned on the Wifi Adapter I IMMEDIATELY got the white screen. I did not have to open a browser, this white screen happen automatically when the computer had ANY internet connection – included LAN – wired Cat-5 connection.
The white screen had the name Conteneur ActiveX in the miniature version but not the main screen.
I also found that if I manually set my DNS server to 126.96.36.199 and second to 188.8.131.52 the white screen changed to say that the site could not be found and showed a listing of suggested addresses and revealed the address as
and suggested alternative sites but I still had no control over the “white screen area” or anything else. Nothing released me from this misery except re-booting with no internet connection.
I could not download any additional scanners in this condition.
I finally discovered that the internet connection worked in Safe Mode (Hold F8 while machine powers up). So I downloaded and updated two tools in Safe mode
Malwarebytes – DID NOT see a problem
Spybot Search and Destroy - – DID NOT see a problem except some cookies.
Also ran these in full windows w/o internet connection again, nothing.
Computer was being protected by McAfee but it had obviously missed this Trojan. Did not run this scan.
Finally a site recommended “Hitman Pro” which was listed on CNET, a source I trust. So again, in Safe Mode, I ran it. (Google “Hitman Pro” and I recommend the download from CNET, it free for 30 days and fully functional.)
It found 40 more cookies and BINGO found
qtqtxjns.exe (I suspect that is a random name for the exe file.)
and called it
So whatever win23.cryptor is – it is NASTY!! I could not find information on this white screen except people saying “bad video card” or “reinstall windows.”
Hitman PRO deleted the Trojan while still in Safe Mode, I booted with WiFi off and ran Hitman Pro – but it wanted internet so I nervous turned it on and wala it ran can found a clean system. Amazing, if I do say so myself! I have rebooted a couple of times now and still stable. Will test the system another couple of days to see if the virus is hiding and reappears… but so far so good!
The infected system was a:
Windows 7 HP Laptop Pavilion dv7-6b78us
Intel Wifi Link 1000 BGN is the network adapter.
Hope this helps you.
