Hello jcyounis,

The issue may not be caused by a hijacker but it might be best for someone to take a look at the system.

Please see the Malware Removal Forum sticky which includes instructions in post #2 on how to provide the logs from Farbar Recovery Scan Tool and aswMBR, which are the logs used in the preliminary analysis.

Then start a new topic in that forum providing the logs so a volunteer analyst can assist.

Best regards,
tashi
