Yesterday my computer appeared to have contracted a rather nasty virus. I knew this by windows explorer constantly crashing and rebooting every ~20 seconds. After browsing the internet a bit I discovered the issue by using the online scanner ESET Online Scanner. Using this and Avast (Malwarebytes wouldn't run, and AVG didn't detect), I was able to delete 3 trojans. This stopped the windows explorer issue, and rescans did not pick up any problems. The reason I post now is because my Firefox is acting up, loading slowly, my add-ons were deleted, and when I open it up it just goes to a blank tab instead of the homepage. So this seems to me to be either virus related or corruption. But I want to make sure my system is clean. Any help would be greatly apperciated.

Hi HelplessComuterUser and :welcome:

Post the ESET scan result ESET

The path to the log file is "C:\Program Files\ESET\EsetOnlineScanner\log.txt" (on 64-bit systems this directory will be "C:\Program Files (x86)\ESET\Esetonlinescanner\log.txt")

 

Also from Avast:

Launch the Avast interface.
Click "Scan Computer."
Click "Scan Logs."
Click a log where the detection was and post it here.

 

Download Screen317 Security Check 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:: If any security program requests permission to access the Internet, allow it to do so

Please download MiniToolBox HERE to your desktop to run it.
Checkmark the following boxes:
* List content of Hosts
* Flush DNS
* Report IE Proxy Settings
* Reset IE Proxy Settings
* Report FF Proxy Settings
* Reset FF Proxy Settings
* List last 10 Event Viewer log
* List Installed Programs
* List Devices (do NOT change any settings here)
* List Users, Partitions and Memory size
Note: When using "Reset FF Proxy Settings" option Firefox should be closed.
Click Go and Copy / Paste the result. (result.txt)

 

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

    Make sure the following options are checked:
        Internet Services
        Windows Firewall
        System Restore
        Security Center/Action Center
        Windows Update
        Windows Defender
        Other Services
    Press "Scan".
    It will create a log (FSS.txt) in the same directory the tool is run.
    Please copy and paste the log to your reply.

 

Please download RKill by Grinler HERE and save it 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.
Before we begin, you should disable your anti-malware softwares you have installed so they do not interfere RKill running as some anti-malware softwares detect RKill as malicious. Please refer to this page if you are not sure how.
    Double-click on Rkill on your desktop to run it. (If you are using Windows Vista, please right-click on it and select Run As Administrator)
    A black screen will appear and then disappear. Please do not worry, that is normal. This means that the tool has been successfully executed.
    If nothing happens or if the tool does not run, please let me know in your next reply.
    A log pops up at the end of the run. This log file is located at C:\rkill.log.
    Please post the log in your next reply.
 

Thank you!
