You can try Avira or Avast! as a free.Avira free is a beast with windows Firewall/Comodo FW,Avast! has some zero day protection and clouds with Comodo FW.Or Sophos Free Antivirus.
Every good free AV now has something annoying attached & rest not good enough.
The only good free AV now is Kaspersky Free. I guess nothing annoying with KF, right? And good protection too.
But sadly only Russian & Chinese language.
Nowadays either I use AVs that I get license from promos, etc... or simply use Windows Defender as its quite good on Win 10.
Thanks everybody! I've made my choice. I'll stay with KAV. If everyone is doubting it, strongly consider actually doing this. I've tested around 20 malwares and the results were awsome. Kaspersky hit and blocked everything and Panda, well.. at least was nice. But once again, it was just a few malware, you should not take this as a serious test. I'll be uploading the pictures.
although I am not a supporter of Kaspersky many reasons you should stay with him.
Pandas to somehow do not trust although some like it but I personally do not.
