PC crashes constantly

[nikoml]

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.

There are a number of sites that give advice about DNS unlocker and its cohorts, for example: https://malwaretips.com/blogs/ads-by-dns-unlocker-removal/.

Try adwcleaner. You have adware, I think, and this should remove it. Defender is not meant for this type of software because it is unwanted rather than harmful... although it doesn't like to be uninstalled easily.

It's simple to use and doesn't install itself permanently. Click 'Scan' > Click 'Clean' > Reboot. Repeat if it finds a lot as shown in the report you will see after rebooting.

These things rarely arrive on their own

 

Often good programs like ADW cleaner won't install or run properly.

Further no single program kills them all.

 

I have found this French one (Junkware Removal Tool) runs in most circumstances, when others will not.

If JRT followed by ADW Cleaner does not do the trick then the bleeping computer site provides real help in cleanup.

 

When the bad guys are gone run the following Microsoft tools, in this order.

 

Disk Cleanup

CheckDisk

System File Checker.

MSconfig

 

Finally Super Anti Spyware runs well alongside most anti virus so load it when you have finished cleanup,

There is a free version.
