Sify has now upgraded its virus checking ability in their client. It seems that now it checks for a antivirus in a pc and then asks a user to install its own antivirus. Suppose if you have avg 7 installed and running properly with all updates and then try to install the 2.8 client(or start it if you already have installed) it will not bother you to install trend or macfee. But if you have no anti virus then it will force you to install it unless you call the call center and disable it. It means that they are using some brains!! quite impressed!
