I had a virus a few weeks ago while I was working on my dissertation; which was really worrying, but I managed to resolve it myself. It came back again and was almost impossible to resolve it; in the end I had to contact a technician who specialises in viruses. I’m not entirely sure why it came back again after so many weeks of my laptop running fine, it could have been a completely different strain of the virus or something in my laptops start up processes could have changed too.
Either way, I will provide some details of the virus and how I resolved it in the first instance and also why I couldn’t resolve it a second time. Hopefully anyone that comes across this virus can see this and try out the tips I used.
Windows (7 in my case) boots up without any problems. I can then type in my windows password and after I log in, I see a window asking which webcam source I’d like to select. Obviously this is the start of the virus and you don’t want to choose anything. At this point; you cannot see anything else – No desktop, no task bar, no windows button – Nothing. Pressing the escape key or clicking cancel will only remove the window and will freeze at a white screen.
At this point the only option I found was to press ctrl + alt + delete to get out and shut down, or to manually press the power button to switch off the laptop.
It’s important to note that there’s information on the internet which suggests that an advanced strain of this virus will actually mean the webcam will take a photo of you and send it to somebody malicious, who will then send you a message saying that you need to send them money to unlock your computer! I obviously didn’t have this much of a problem but here’s some information on that – http://www.pchelpforum.com/xf/threads/white-screen-virus.138022/
I did some searching around in the first instance, using my iphone to find that it isn’t a common virus and hardly any information on resolving it. I found that as soon as you type in your password at windows login and you ‘enter’ this –> Hold down ctrl + alt + del for a few seconds and then hit the esc key. You may have to hold down ctrl + alt + del for up to a minute, you’ll find out either way whether it was too long or too short.
This works by allowing your usual (safe) processes to start up in the background, but not the webcam virus. After you hit the esc key, you should (hopefully) be able to access your desktop as normal. If you do, you really should check for viruses using Norton Anti virus or other virus detection software. I would also check for recently downloaded files and remove unless you are sure they are completely safe.
As mentioned earlier, I resolved this myself a few weeks ago but it came back a few days ago and the resolution didn’t work. Whenever I held down ctrl + alt + del and then pressed esc, the webcam window would always appear. Then the white screen wouldn’t let me do anything so eventually I contacted a technician who specialises in viruses.
He found that there was a prokill virus which automatically disables normal windows processes on start up; which means it’s almost impossible to resolve yourself. There were other associated viruses/issues which he resolved for me. He wasn’t sure whether it was the exact same virus as the first time or whether it was from a different source which meant it was more of a problem. The other option for me if he couldn’t solve it would have been to use system restore from getting into the boot start up menu using F8 as soon as windows starts up. However, when I did this, it wouldn’t let me use the last and only restore point – I think the virus caused this problem too, as I’ve used system restore a year ago and it worked fine.
The other option would have been to format the hard drive and reinstall Windows 7, luckily I have my documents and photos backed up on an external hard drive; which I definitely would recommend to anybody.
Good luck if you have this virus and hopefully the procedure listed here helps. I don’t have much more information on this, but if you think I can help further; feel free to tweet me
