Can 2 different anti virus work for a PC?free anti virus

Only one anti virus program is recommended to install on one computer at a time. If more than one programs are installed, the computer will begin to stuck badly and will show very delayed execution and slow performance. I verified this by installing McAfee and Norton at same time on different computers(pentium-4), all of those computers failed to start in normal mode, or took about 10 minutes or more to start normally.

Can 2 different anti virus work for a PC?internet security software

Yes they can work ....but its not recommended...

So better use one antivirus.

In my opinion Kaspersky internet security is best antivirus it also include inbuilt firewall and also algorithm to detect virus which are still to be discovered.

NOD32 is my second choice.

just install one of them and keep it updated.

you will never have problem trust me .... i havent formated or infected my pc with virus from last 2 years ...kaspersky alone is sufficient for virusees and everything.
No it is not recommended, as the software will have ''conflict'' with each other thus slowing down the PC process.
Of course, I'm used to use four in my laptop, but it fights each other, and when one detects a virus, another comes, and my laptop goes to a -- what is called -- a ''dialog box rush''...? Then your pc hangs and you got the virus quarantined after restart. But don't forget, you'll lose data as the computer will restart AUTOMATICALLY.
Yes - two different anti virus can work for a PC.In my PC there are two different anti virus 1st is AVG %26 2nd is Mc Afee.
