Title: svchost.exe attempts to connect to a malicious URL
Post by: Stewiee on February 04, 2014, 10:47:11 PM
I have tried to fix this issue with AVAST, Malwarebytes, Combofix, and TDSSKiller but have not been able to fix this error.

Here is a screenshot of what pops up every 5-10 minutes :

Hi,


Please download Farbar Recovery Scan Tool (http://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/) by Farbar and save it to your desktop.

Note: You need to run the version compatibale with your system. If you are not sure which version applies to your system download both of them and try to run them.
Only one of them will run on your system, that will be the right version.

Tell me how popups manifest?



Download TDSSKiller (http://media.kaspersky.com/utilities/VirusUtilities/EN/tdsskiller.exe)  and save it to your desktop

  Execute TDSSKiller.exe by doubleclicking on it.
Confirm "End user Licence Agreement" and "KSN Statement" dialog box by clicking on Accept button.
Once complete, a log will be produced at the root drive which is typically C:\ ,for example, C:\TDSSKiller.<version_date_time>log.txt


Please post the contents of that log in your next reply.
