Firstly post a screenshot
of the Startup Tab of Msconfig, expanding the Command and Registry location or manually write the details..
Then download Malwarebytes
and run a scan and clean everything it finds, then do the same but with Microsoft Security Essentials
. Lastly run an ESET Online Scan
Next download CCleaner
, go to Startup Tab, disable and remove all the Startup Entries. You may want to see if this also helps: Anti-rootkit utility TDSSKiller
. Finally run a SFC Scan
If none of this helps, you could post it in Security Section in this forum, or in a Forum full of experts who can handle viruses.
