Is there any problem if i provide 2 antivirus softwares in a PC?

Yes and no. If the both AntiViruses have real time detection, then they will conflict and slow your computer down. They can even crash your computer! So, the general rule of thumb is one hardware firewall, one software firewall, one AntiVirus, and 2-3 adaware/spyware removers.

Yes, there can be loads of problems. Most anti-viruses are incompatible with one another and can cause severe driver conflicts, which may even lead to crashing of your system. Moreover both of them do the same job, i.e. catching viruses, so one is as good as two.

you dont want to do that it will corrupt the other... only use 1 antivirus, u dont need to have 2, actually if you install other antivirus it will tell you that u alredy have one, and u might want to get rid of tthat one to install the new one..
No, but don't run both at the same time. Only run one.
If you use 2, they won't work with each other, it is like having two headphones for only 2 ears... it just doesn't work!

Good Luck :]
