Specs: N/A
What specific tasks does antivirus software perform that would interfere with internet connectivity please?

Antivirus software should have no effect on connectivity. That said it will cause a little lag if you have a email scanner checking emails out, but not general browsing.(Not a noticeable slow down)
A fake/antivirus virus program can cause all sorts of problems, slow things down and block it all together.
To check yours just disable it, leave the firewall running, and see if things are faster?

Thank you very much for your response. That is quite helpful information, which seems to correspond more with common sense than what else I have seen online, as unfortunately the web is littered with comments which indicate otherwise, and these statements do not seem to make sense me when you read what antivirus programs do, such as looking for signatures and behaviours ect..., and so I was wandering if there was some greater functionality that included the internet which I was missing out on. But according you to apparently not, so I'm glad to have learned that.

I've come across this before on other topics I have looked up and I think what happens is that someone will make a sentence that is either totally misguided or was true 10 years ago and then everyone else,jumps on the bandwagon, and on a mass scale, resulting in similar statements, typically with no beef, popping up all over the internet.

You had me thinking I was wrong there for a second, so called five computer shops to clarify your question and my answer.

Affects On Internet Connectivity:
1) An AV program is made to have no affect on internet connectivity.( We wouldn't buy ones that did?)
2) AV programs like Norton and Nod32, Mcafee will chew up pc resources CPU and RAM, which slows things down. (Not connectivity.)
3) If you are running more than one AV program, it may cause connectivity issues. Because of conflicts between the two AV programs.(Thats why you should only have one installed)
4) If you have limewire P2P programs etc running, you may have conflicts with your AV program, which may cause connectivity issues.(Thats why they are removed for malware removals)
5) If your pc already has hidden malware running, which is designed to cause connectivity problems, through to no connection at all.
6) Even web scanners and email scanners should only hog resources, not change the connectivity.
7) Heavy computer use in your area will affect connectivity, not your AV program.

This was the same run down of answers from all five computer shops? So we must all be wrong then? I wish I was getting paid $100 plus p/hr to give the wrong advice :-)

That's what I asked my question for to find out in what way it can affect connectivity issues, and installing two antivirus applications does cause connectivity issues, so that is one, and an other is sometimes after virus removal you can have winsock corruption.

Thanks for going to the effort to call around to find an answer though, perhaps it was just a miscommunication as to what information I was looking for.

:-)lol. And the winsock corruption would be caused by a virus, not the AV software removal. (If it wasn't corrupted the AV software wouldn't have caused any damage.)
