Hello, couple of months ago there were some conversations recorded (or contacts) that i never had (or know) and some messages send that i didnt send. I then contacted yahoo and they said to change my password and others stuff. I changed my password and then again appeard some message or contact (not sure). Ill get back to this later (it will be a part of my question).

 

Recently i noticed that my fans were very loud. I then downloaded SpeedFan and discovered that my GPU was about 80C, 90C idle so my GPU fan had to work 100%. I suspected a virus (since i downloaded some game and since then i couldnt turn my Microsoft Firewall on, tho i did it manually under "services" after i looked it up on internet).

 

Then i ran Norton Security Scan, Microsoft Security Essential, McAfe Security Scan Plus. All the results came out: OK.

 

Then i ran BitDefender quick scan online. It was fine too.

 

Then i ran ESET online scanner online. First it discovered (sorry, i cant remember fully) something like avs/agent.NGJ.In fuller description i think i even saw some folder "adobe" and it made me think that that virus (avs/agent.NGJ) could cause the fan problems. Then i think ESET deleted it, because i ran ESET again and there wasnt any problem. And after that my fan started to work normally.

 

Then i ran ESET again, i checked more boxes to look and search (E, F, etc.) and than i saw this: a variant of Win32/BitCoinMiner.N application

 

I ran ESET again and it came out fine.

 

So, i have couple of questions.

 

1.Were some of this viruses been on my PC long, that they could cause my yahoo mail to be compromised ?

 

2.Were some of them causing my firewall to be shut off (so that i could only turn it on manualy by "services" and the fan (GPU) problem ?

 

3.Do you think ESET deleted them so i dont have anything to worry about anymore ?
 

Any help would be appreciated.

p22002970.gif Download Security Check from here or here and save it to your Desktop.

  • Double-click SecurityCheck.exe
  • Follow the onscreen instructions inside of the black box.
  • A Notepad document should open automatically called checkup.txt; please post the contents of that document.

NOTE 1. If one of your security applications (e.g., third-party firewall) requests permission to allow DIG.EXE access the Internet, allow it to do so.
NOTE 2 SecurityCheck may produce some false warning(s), so leave the results reading to me.

p22002970.gif Please download Farbar Service Scanner (FSS) and run it on the computer with the issue.

p22002970.gif Please download Rkill (courtesy of BleepingComputer.com) to your desktop.
There are 2 different versions. If one of them won't run then download and try to run the other one.
You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.

rKill.exe: http://www.bleepingcomputer.com/download/rkill/dl/10/
iExplore.exe (renamed rKill.exe): http://www.bleepingcomputer.com/download/rkill/dl/11/

  • Double-click on the Rkill desktop icon to run the tool.
  • If using Vista or Windows 7 right-click on it and choose Run As Administrator.
  • A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
  • If not, delete the file, then download and use the one provided in Link 2.
  • Do not reboot until instructed.
  • If the tool does not run from any of the links provided, please let me know.


If normal mode still doesn't work, run the tool from safe mode.

When the scan is done Notepad will open with rKill log.
Post it in your next reply.

NOTE. rKill.txt log will also be present on your desktop.

NOTE Do NOT wrap your logs in "quote" or "code" brackets.

It all depends what you're infected with.

If you're infected with a rootkit or your MBR is infected hard drive has to be formatted while reinstalling Windows.
