Has anyone got COMODO antivirus up and running? Would like to hear from them if they have. Thanks

The only reason I can see to run an anti-virus program on Linux, is if you are sharing files with Windows, or Mac's. Linux viruses are few, and far. Mostly only effect the originating machine.
I did have something that crashed my desktop, and brought me back to my log in screen. The simple fix was emptying the browser cashe. Then not returning to that page.
