After I run a full anti-virus scan (avast!) my programs seem to take longer to load the next time I turn on my computer. If I run a boot-scan... they take even longer. 
Even some of my pre-installed Tray Icons are missing.
My question is... what happens during a scan to cause this?
Try to keep the answer(s) as simple as possible. 
BTW This happens even if no viruses or PUP's are found.

Same older ticket number too. I wonder what's going on over there?
...so I guess I don't really need a current topic email from them.
