Have a good firewall and virus protection and you should be alright. No guarantees though.
Any ISP in India logs activity for at least 7 months, so yes. But they can't "hack" your system and see what you've browsed till now if that's what you're asking.
Just watch that the cable operator doesn't set your network to be "Home" or "Work" connection as this basically lowers
Windows' defenses and helps greatly with the spread of malware.
I've seen installers do this on numerous occasions and it sucks having to chew out these poor guys in front of customers.
It provides an extra layer and may help with other things but there is no guarantee. The guarantee of security that anyone can realistically give you is to tell you that if your data is so important, keep it on a machine that never connects to the internet. Inside a safe. In a hole so deep you'd be half-way to the opposite side of the world (which people on the west coast of India should be somewhere off the cost of Peru/Northern Chile).
