At first I was used to purchase some known anti virus software which cost me a high. Thanks to ESET which saved a lot of money & data. For last 3 years i’ve been continuously using ESET and satisfied with features & service. When ever I call them for a service or process their customer care helped so quick & politely.
This year I purchased another single user antivirus for my new notebook & got an offer card for winning gifts. For true I won a SAKRI pendrive. There are a lot of facilities helped me a lot like file protection, network services, parental control & server edition antivirus etc. So before anyone thinks of a costly antivirus will protect you more analyze your choices.
