Use Avast, its free and it works wonders. I have been using it for some years now and no viruses so far, atleast i think so.
In the past, I've used Norton AV and I must say it wasn't worth it because it's a huge drain on system resources. That was almost 4-5 years ago with a much slower processor but the experience was so dreadful that I haven't tried using it again. Been using Avast AV, the free version, for almost a year. It's great, provides the basic protection I need with auto updates and all. What's more, I simply love the audible update notifications. Makes your PC come alive.
I am using the Free version of Avast! Anti Virus. I like it. It doesn't have annoying ads unlike Avira.
I used Anti virus avg. this anti virus is the much better than other anti virus because it is find the virus on the system delete all virus without any warrior. and we can download this anti virus as free of cost
I have used quite a few anti-virus programmes over the years. I have tried Kaspersky, Avast and AVG (free versions) with okay results. At the moment I use Norton. I feel that I have good protection with this product and the current version does not hurt computer performance the way earlier versions did.
im using kaspersky but i dont like it at all. for some reason it has really slowed my computer down (my computer isnt shitty).
