Hello,
Last Tuesday (20/05/2014) when I arrived home I had a surprise with my PC. The screen was "scrambled", and the machine was stuck and non-responsive. I had to reset it. When it rebooted, Malwarebytes Anti-Malware started to update to version 2.0 and completed its update. It made a quick scan and everything was clean. However a strange thing happened: MS Security Essentials popped-up with the red icon and saying that the computer was at risk. Next the explorer crashed and a BSOD showed (STOP 0x000000F4). This was a very strange thing as I have not installed/removed any hardware/software (besides the update that started after resetting). I reset once again. The computer booted again and after everything had loaded all seemed to be OK. I was preparing to play League of Legends (had double-clicked the shortcut on desktop and the window with the “Play” button showed, however even before I started the login to the game process the same thing happened all over again: MS Security Essentials followed by explorer and same BSOD. This was weird.
I restarted in safety mode and run a full system check with both Malwarebytes Anti-Malware and MS Security Essentials. An Obscure java Trojan/virus/malware popped-up. I cleaned it and reboot again in normal mode. Meanwhile I ran a checkdisk without any errors. No more alerts and no more BSOD. Everything seemed to be working just fine.
However when I tried to run League of Legends, it simply did not start. The loader started but it wouldn’t launch the window of the game. I checked the process at the Task Manager and it was only 120KB and the explorer.exe increased its memory/cpu use (I have the Core Temp app running on the mini apps and it showed that all the processors were having high activity) but nothing happened. When I try to kill the League of Legends launcher process it simply would not ended. Also tried to kill explorer.exe without any success. Tried to end session and tried to shut down but, at first it did not work and staid stuck at the closing session screen/shut down screen (only with reset I could restart the computer), now it already ends session/shuts down/restarts without any problem. However the last couple of times, I noticed that the network icon by the clock had a blue circle on it as it was starting/connecting. That never happened before. I tried to double click it – nothing happened. Tried to go to the Network and Sharing Center via the Control Panel, but it simply does not open and gets stuck trying to open. When I go to the Task Manager, select that application, right click it and go to process it selects explorer.exe on the processes tab. I try to terminate it but without any success.
In my attempts I also tried to make a system restore to an earlier date, but as the problem persisted, I reverted the restore.
Apparently everything is working fine (internet access/speed, running office aplications, flash content, java content).
Everything is up to date.
Can anyone help me with this situation? Can this be a virus/trojan/malware? I have ran out of ideas here...
