SOURCE: what i can do about vires free

Nod 32 is one of the better AV progs IMO. I use it myself but I also run Malwarebytes as a complementary AV.

You can download the free version from here

I find that both work well together but that is just my opinion.
Don't forget whatever AV progs you have are only as good as the number of times you run them, make sure they are updated regularly (nod32 does this automatically) and most important use them to scan your system at regular intervals. How often depends on your internet usage but I would recommend a minimum of once a week.
