I know, PC constant crash can be caused by various reasons. But now the problem happens on the computer when sorts of ads by Dns unlocker appear. I tried to find the reason and unluckily I was informed that the system could be attacked by dns unlocker malware which could consume CPU usage and affect system performance (see info 'what is DNS Unlocker'). I have no idea how to deal with the issue because antivirus software found nothing.
