Pirated something lately ? :)

I usually recommend a scan with this anti-malware program:
https://www.malwarebytes.org/
You can use the free version.

Does it give you a bowl of borscht?

check your autorun entries > https://technet.microsoft.com/en-us/sysinternals/bb963902.aspx
after this check your hosts file > http://www.askvg.com/how-to-reset-hosts-file-to-default-in-windows-xp-vista-and-7/

msconfig
under general you can try logging in with diagnostic startup
if all is fine with that check what programs are activated on startup from startup tab
might just be a simple script
For otherpeoples pcs I usually usemalwarebytes to remove crap from their pc

It generally happens cause you installed a software(generally free) and didn't pay much attention during the setup
You have two options:-
Either manually stop the startup service of that software(which i prefer).
OR use a another program which does the same thing(Many good softwares have been mentioned above).

Also if you frequently install unsecure softwares or programs their might be some other stuff happening in your computer you don't know about.
