Thanks for your support.
I can't remember whether I turned AV off however it was my intention to do so . I use MSE. I did scan with MSE and SuperantiSpyware before I started the upgrade and I made sure Vista and MSE were fully dated before I started.
Unfortunately because IE8 was hopeless, I could not update any programs/files after I upgraded to Win 7 so downloading a new copy of MSE from Microsoft onto a memory stick means I am currently using on MSE a version with a database which is 4 months old. Same with SuperantiSpyware with a database which is 6 months old. When I plug these programs into the Dell's USB they run but cannot update their databases because the Explorer link is present but only drip feeding a few bytes at a time.
I am kind of pre-empting what you might be about to tell me and that I may need to do a clean install unless there is a way of transferring scanning programs which have their data bases updated before I copy them onto the memory stick. If this can be done which programs should I use?
I have loaded SuperantiSpyware program onto my Dell and when I came through this morning the Dell was on although I had put it to sleep last night. SuperantiSpyware had done a scan at 2am finding 25 threats (tracking cookies etc) which seemed to be from the old Vista days.
Better explain the storage hardware. There are twin physical disks on my Dell, both 330GB which are in reality 298GB after formatting. So 2 disks however 3 drives.
Disk 1 C: Operating E: Recovery
Disk 2 D: Data
One of the reasons I did not wipe the primary hard disk in the Dell was there is a 10 GB recovery partition (Drive E). The C and E drives are separate partitions of the booting disk. Dell do not give you a Vista CD disk. This recovery area E is still there I am sure.
After the upgrade there's still 3 "Drives" on my Inspiron, the Vista Recovery drive partition E and the new Win 7 drive partition C and the second 298 GB hard disk, the D: drive which has data files on it.
Prior to doing the Vista Win 7 move I used EaseUS Todo Backup to do a Disk and Partition Backup of the C: and E: disk.
I also checked on Restore Points on the C: drive and there's one for yesterday 13/12, 12/12, 11/12, 10/12, (14 points for 10/12), There are also 8 from earlier in the year which are probably backups to a USB hard disk using windows backup.
Going "back" has several options however something I have never tried. At least we can do what easiest and best either backwards or forwards. Please advise what I should do?
