After scan my PC and I click for cleaning errors, then I cannot browse internet !
(IE6.0). Fortunately I get the option UNDO the DELETE and I get everything OK.
My question is: How can I use A1clickUltraPCCleaner and avoid this happen?
Thanks.

   There is probably only one item that was removed which caused Internet Explorer not to work.  Run A1Click manually (not automatically) and look through the Results.  Do not clean any that may be the offending item.  Run Internet Explorer to make sure that it still works, then clean one at a time in A1Click until you figure out which one is causing the problem.  Once you find it, you can have A1Click always skip it and it will never be a problem again.
   I would like to know which one it is so that I can rewrite A1Click to always skip it too.

   Someone else has reported a similar problem.  This person removed addproxy from the Startup items in msconfig (type msconfig in Run to start msconfig) and Internet Explorer started working.
   From what I can tell addproxy is not a virus and it only needs to be run once, so you probably do not need it in Startup.  My guess is that A1Click removed a file that addproxy uses and so it stopped working.  If you can figure out which file that is, I would like to know.
