nah, don't vory, there is no ''net-work virus''
I have had this a couple of time, but ''only'' on special servers, or when there where lots of lag.
This might happend if your connecting and there is many that chat, i tried too, there is 3 ways:
1. Re-enter
2. Wait until you found a place ;P
3. Restart your computer

This is just usual connecting problems, first i tried this was on one of Irony's level. I waited until it stopped with warping and ended in other end of level =p
If it continue, god will ban da lag ;p, and you will soon loose your connecting.
There is no way to fight back lag at what i known ;p
I do always rid of warp error with restart, try it
