No probs 
Yep i use Avast & Nod, but not at same time, but Avast is my main AV 
I do know that if i have Avast running & then download the shareware version of Panda, Avast says virus found, its actually a false positive, ie not a Virus, like i said it cause Panda dont encrypt their virus sig file, same happens if U use the online Panda Activescan scanner, it was a while wehn i got my alert & i think the virus name is different, try a search of the forum for panda to find post where it is mentioned 
How do U mean email protection, do U mean Avast email protection?One of the many good thngs about avast is its email scanning, it can also warn U of much more than just infection, ie suspicious subject, or code hidden in the html, but i find it better to customise the protection in the internet mail provider to get the maximum 
Others will tell U more than i know about the ones U have listed, but im sure the 2 Panda ones arnt viruses, the swp file one i not sure about, if it 98, U could try shutting down into real dos mode (last option) & at the command line type del win386.swp, that will delete the swp file & windows will make a new one when U reboot
