The answer varies from individual to individuals.
It depends on you what you choose. There are many antivirus software available. I think all of them are good. None can provide 100 percent protection.
All of them have some minor or major drawbacks.
1. Web protection is better in kaspersky.
2. Threat detection and removal same.
3. There is a rescue mode in bitdefender
, kaspersky does not have
.
4. Price: Bitdefender total security almost equals to Kaspersky internet security.
5. Anti-banner is only available in kaspersky.
6. No. of virus signatures: Kaspersky around 6.1 million, Bitdefender 11869704(date June 7, 2014)
I used kaspersky IS in the year 2012, 2013 (paid). Now as I have two OS in my PC one has eset SS. Other has Bitdefender Total Security. I have obtained serial keys of those from this forum.
