Every time i boot the PC, i am not able to surf the net as most of the sites do not open even when there is no problem with the internet connection. I searched for a solution online and found out that malwares are responsible for this. So I downloaded and installed MALWAREBYTES-anti malware and ran a scan which detected some malwares on my PC and deleted them. The problem was solved and my surfing returned to normal. But when I switched off the PC and rebooted it, the same problem occurred again. I ran the malware scan again and it detected a malware at the location 'C:\Users\Anto\AppData\Roaming\skype.dat'
Every time i reboot, and run MALWAREBYTES, it detects and deletes skype.dat but it keeps on returning.
After some time i found out that the malware regenerates itself after 10 minutes or so as 10 minutes (approx) after deleting the malware, my surfing problem returns again.
I manually tried to find 'skype.dat' in the location 'C:\Users\Anto\AppData\Roaming' but could never find it. QuickHeal never detected it. I tried to find some other online solutions and tried combofix and roguekiller but none worked.
Please help me resolve this problem.
