Morz if you also have Windows XP you should consider installing Skype on both computers. Then get Mum a set of headphones so you can talk and walk her through the procedure - or any other problem while both of you are in front of your computers. Then you can keep up by showing the same page on your own computer. I use this quite often when helping folks. Having said that back to the issue. Have Mum install Crap Cleaner, linked below. Before using it go to Add/Remove Programs and remove the AVG install. Now run Crap Cleaner with the default settings to get those corrupt files off the machine and then do your install. If you or Mum are concerned about Crap Cleaner (it is a brilliant little freebie actually) you can create a Restore Point before moving forward so you can go back if necessary. This is just to give you confidence, you will not use it. Here is a link that might be useful: Crap Cleaner

Open AVG > Click on E-mail Scanner > Configure > E-mail scanning > uncheck > Certify mail > ok.

For those who aren't thrilled with Link Scanner or those who may just want to see how well AVG operates without it, it is not necessary to delete and reinstall. Double click on the icon appearing in the Notification Area/System Tray>In the appearing interface double click on the Link Scanner component>Uncheck the Enable the AVG Search-Shield (need web browser restart)>Click Save changes. I do not remember if a restart is required. I am sure AVG will advise if necessary. DA

I am wondering if this could be a run away log file. when you have a problem with hard drive space disappearing, look for a gigantic file. In Windows XP, open Windows Explorer (click Start, All Programs, Accessories, Windows Explorer). Click Search and All Files and Folders. Enter *.* in the file name. Tell it to search My Computer. Select Specify Size and pick At Least in the first box. Enter 1000000 in the second box. Click Search. We are looking for any really large files if you find something get the info on where it is and what it is. Also do this, click start, control panel, administrative tools, event viewer, there you will see 3 options double click on them one at a time and see if you have any warnings if you see anything unusual just double click on that entry and it will open a box with info and what the code is. In the security especially look closely for signs of any one other than you logging into your system. While in control panel open user accounts and look to see if you see any new or additional user accounts listed in there. do you have a firewall on your pc? if not at the very least get the windows one turned on but I would advise going and getting one of the free ones, and setting it up, just in case someone has gained access to your system. work with that program xinorbis it will tell you exactly where the big files are that is what it is for so you can see exactly what is taking up that space. It will make pie charts and lists and tell you a lot of info. Another thing to check is how much space are you allowing system restore to use? you can adjust the amount you let it have. Start, control panel, double click system click the system restore tab then settings if the slider is all the way on max move it down a bit hit apply ok, that might show you have some space back check and see. And just in case you have not done this already on your browsers clear all the cache, temp internet files, cookies, history, offline content, every thing. If you need directions just tell us. Go to your trash bin and make sure it is completely empty. do you have any type of peer to peer sharing programs on your pc? like sharing music of videos? If so lock them down and/ or get rid of them. Have you installed itunes by any chance and loaded music? sometimes it can duplicate files. you can download a free program called belarc advisor which will scan your pc and give you a list of everything that is on your pc, but it also has a function that will tell you if your hard drive is healthy or if may be failing, that would be something worth checking. I am just wracking my brain for things that could be causing this. But I tell ya I would be thinking of trying a system restore point prior to that date that you said it pointed to and see what happens before you no longer have the option to go back there. As I said if it does not help you can just turn right back around and tell it to undo it. To be doubly sure have it create a restore point right before you do the go back. Do that before you make any changes to your system restore like moving the slider to use less space, would not want to lose the restore point you needed. I will keep thinking on it as I am sure others are too.
