hi!
@claudiu
For me the best antivirus are: Kaspersky, ESET, Dr. Web, MSE . I test all of them and I use some of them and I never regret it.
By the way if you want privacy and a better antivirus pay for him, if you want to be a donor of your data to a 3 party use a free one.
Look at those test with a gram of salt. On some test Bugdefender is best solution in galaxy but is just marketing.
