I am using fsecure since Pokopiko former member recomended to us maybe 5-6-7 years ago cant remember exacly when,first a workstation joined with sygate as firewall,it was a5.29 version i think.
When sygate got sold to norton-symantec im using fsecure set called
antivirus client security which is all in one,like av,firewall,email checker,antispyware and such,and i can tell you i am preetty please with it as i never found some virus,trojan or spyware with some other app.
Also its got one more really significant feature which is harder to find in some other app but due to nature of that """feature""i cannot mentione it here
If you need a real good all in 1 app check fsecure-you wont be dissapointed for sure
EDIT;;;I always used a corporate versions so i really dont know how good their appz for home usrs are???Anyway check here and see
