I was reading the change log of Panda cloud at filehippo and one of the changes is given below:

* Ability to run alongside other AVs and Anti-Spyware. Can now be run alongside other security tools and scanners.

Code:

Its main protection is for people who are connected to the internet. But has good offline protection too.

We dont need to download any updates for database/signatures since it is cloud based.

The bad thing is if you choose to opt out of the Panda community, ie, If you uncheck the option to send anonymous data about infections to Panda, you dont get realtime protection.

I installed it alongside Norton Internet Security to check the compatibility, seems to work fine. Quick scan showed my PC is clean.

Try it if you are interested, it can be downloaded from the filehippo link that I have posted above
