I was wondering is there any way to avoid disablement of my updates, and what blacklisting really is.
If that doesn't work I saw there are many freeware antivirus programs, which one you would recommend.
And as the most important question, i'm not sure what i need to do before installing new program(antivirus),
do I have to uninstall previous, or do I have to also erase it, what are the steps
( i apologize in advance for my mistakes in english)
