Cannot update antivirus

This does not sound like a malware problem. And your logs only show a little bit of junkware which would not typically be a cause of an issue like this. I suggest that you first try uninstalling Eset and then reboot. After reboot run the below first before you reinstall Eset.


Now please download Junkware Removal Tool to your desktop.

• Shut down your protection software now to avoid potential conflicts.
• Run the tool by double-clicking it. If you are using Windows Vista or Seven, right-mouse click it and select Run as Administrator.
• The tool will open and start scanning your system.
• Note: That JRT may reset your home page to a google default so you will need to restore your home page setting if this happens.
• Please be patient as this can take a while to complete depending on your system's specifications.
• On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
• Attach JRT.txt to your next message.

Now reinstall Eset and see if it is working okay.

 

You're welcome.


If you are not having any other malware problems, it is time to do our final steps:

1. We recommend you keep Malwarebytes Anti-Malware for scanning/removal of malware.
3. Renable your Disk Emulation software with Defogger if you had disabled it in step 4 of the READ & RUN ME.
4. Go to add/remove programs and uninstall HijackThis. If you don't see it or it will not uninstall, don't worry about it. Just move on to the next step.
5. If running Vista, Win 7 or Win 8, it is time to make sure you have reenabled UAC by double clicking on the C:\MGtools\enableUAC.reg file and allowing it to be added to the registry.
6. Now goto the C:\MGtools folder and find the MGclean.bat file. Double click ( if running Vista, Win7, or Win 8 Right Click and Run As Administrator ) on this file to run this cleanup program that will remove files and folders related to MGtools and some other items from our cleaning procedures.
8. Any other miscellaneous tools we may have had you install or download can be uninstalled and deleted.
10. After doing the above, you should work thru the below link:
