I was going through a horrible experience of my limited bandwidth usage. Once I would connect to the broadband then send bytes would start sending huge amount of bytes and at the end of 5 mins Send Bytes would have crossed 10 times to receive bytes and consumption was around 10MB even in idle condition just after connection.
I installed Kaspersky and 19 threats were detected and I deleted subsequent Files.
Right now my internet connectivity is working as per my expectation. Under the same condition as mentioned above total consumption of bandwidth is around 300KB and no more unnecessary byte send from my Ethernet. Earlier I thought it was due to ethernet and changed it but did get same result.It really worked for me.
But scanning process is little bit slower than norton and understanding its feature is bit complicated.
Price is around 500/- INR and you will have 3 license users which is great for using in 3 different machine.
