Everytime when I open Google Chrome my home page changes to esurf.biz which I cannot get rid of. I have tried to reinstall Chrome, but it does not help.
Your computer is infected with a browser hijacker and, that its possible, with an adware or potentially unwanted program (PUP). Let’s start cleaning out. I suggests use AdwCleaner + JRT + Malwarebytes Anti-malware. These apps are free. Links below:
AdwCleaner by Xplode from http://www.myantispyware.com/download/adwcleaner
JRT (Junkware Removal Tool) http://www.myantispyware.com/download/jrt
MalwareBytes Anti-Malware from http://www.myantispyware.com/download/malwarebytes-anti-malware
- Close all open programs. Double click on AdwCleaner, then select I agree if it appears. Click Scan. When the scan of your system has completed. Click on Clean button.
- Run JRT and allow the program time to run.
- Run mbam-setup to start the installation of Anti-Malware. It will open the Anti-Malware Setup Wizard. Follow the prompts. When the installation is done, click to Scan now to perform a system scan. When the scan has completed, click on the Remove Selected button.
If they cant get rid of the esurf.biz hijacker (in some cases that does happen) then reset Chrome settings to default state (look the steps http://www.myantispyware.com/2016/01/06/how-to-reset-google-chrome-settings-to-default/) or ask for help here.
