Ordinarily when I go to clean a PC infected with malware I will head over to malwarebytes.org and grab the free version of their software.
Many malware infections will prevent you from going to their site so you may have to download on a different PC or do so in safe mode with networking. If using a different PC, then transfer the malwarebytes setup file via USB stick.
Then you need to boot Windows in “safe mode with networking” so that you can install malware bytes and download updates.
The other day, though, I had a real badly infected PC where malwarebytes cleaned and fixed over 1000 problems but the machine was still infected. It was easy to determine it was still infected because it would not allow me to go to Windows update.
So I called out the big gun – ComboFix.
ComboFix comes from a website named bleepingcomputer, whose name might scare away the uninitiated.
I ran ComboFix on the malware infected PC, it cleaned the last remaining malware and the customer has been happy ever since.
The good news is that both of these PC infection cleaning utilities are FREE.
Once your PC is clean, protect it with one of my recommended internet security suites.
Here is a video I did highlighting these utilities:
