I am open to all suggestions on this one as I am plumb out myself. Yesterday I was getting warnings about AVG being out of date, therefore I downloaded AVG8.5 and installed it. However when it told me that settings would not update until I had restarted I chose to 'restart later'. I then later ran Advanced Windowscare professional to clear out temp files etc. Finally when I switched it off it gave me the option to 'install important updates' prior to shutting down (Windows updates I assume) - which I chose.
Later when I switched the PC back on I found I was unable to start commonly used applications like Mozilla and Trillian, getting the error message 'Windows cannot access the specified device, path or file. You may not have the appropriate permissions to acces the file' - however I have checked and my account has Admin rights. I then tried to start Mozilla from the c;prog file firefox path but again it would not let it start. However some apps that I access on a less often basis seem to start and work fine.. Also Outlook was looking for an AVG 7.5 file that wasnt there. The other problem is that when I run IE altho it will browse fine I cant type anything in the boxes, or cut and paste from anything I have typed in notepad. No errors come up though, it just wont get a cursor in the boxes. I am alos unable to start Security Centre to check my firewall is running (it keeps alerting it isnt) and when I try and start my Firewall Comodo I get an error saying app failed to initialise.
I have tried doing a restore through Windows how that fails too with a runtime error, and then theres no calendar restore point. I also tried to use Windows Advanced Care to go back to an earlier restore point, with no joy. Finally I also cant open Internet Options in IE.
Any ideas to whats happened - some sort of mishmash when AVG, Windows Updater and Windows Advanced Care have all contended? Also any suggestions to how I get it all working again without seemingly the ability to restore. Just to add I am running XP, sp2 I think.
Thnaks for any pointers.
