Hello, Yesterday I installed over the top of the previous version the latest one. During startup this morning a panel appeared and clicking on Switch To quite a few time did nothing. Although the Avast icon appeared in the taskbar this Server Busy panel was associated with it. What also was affected was the Network System icon that appeared with a red cross on it and so I was unable to load various of the functions. I went online on my wife's W7 computer, on which I also installed Avast Free yesterday, and Googled the problem. I found reading about doing a clean boot on Vista a bit offputting so I did a restart and went into Safe Mode and selected Last Known Good Configuration which resolved the issue. Well, not immediately as prior to that I tried to do a restore point recovery whilst in safe mode using Tom's Restore Point Creator interface but got a critical error panel popup. Whilst in safe mode I then accessed Shane's tweaking.com Registry Backup restore points which are located on an external usb drive but I was informed there were errors concerning that out of the 16 parts of a restore poin there were errors with 6 of them. Hence restarting again and selecting LKGF.
