I think Teo Gaona is asking whether (certain) paid antivirus companies will give you a virus out of revenge if you fail to renew the subscription. Well, not revenge, but to show you what happens if you don't use their product. He knows about free antivirus solutions, but feels he is being targeted by the paid companies he has already been in contact with. Thanks everybody though for confirming that the big names mess with the system too much. I have never had any active viruses or problems with Avira, except that they have started to show an ad screen. I guess I can live with that.
