|"floppy diskette error "|
I've heard of that error before.
Apparently some Dell bios versions have a bug that generates that error message when you do NOT have a floppy drive connected if a setting in the bios is set wrong for the situation
"When I rebooted first time an alert message came saying ' New hardware found. Floppy Disc ' "
The same bug also causes Windows to falsely detect a floppy drive.
If you have loaded bios defaults, the default may be for the situation where there IS a floppy drive connected.
In this case, you need to press F2 while booting when you see the line to do that to enter Setup or similar, and set the Diskette drive to OFF.

Most third party anti-malware programs that did not come with Windows have one or more resident modules - a program that runs all the time in the background looking for suspicious activity.
The free and paid versions of AVG 2011 definitely has a resident module - the Resident Shield .
(The paid version also has a software firewall which may have it's own resident module)..
The Virgin Security software probably has at least one resident module.
It's NOT recommended that you install more than one anti-malware program that has one or more resident module(s) because the resident modules of different anti-malware programs are likely to CLASH with each other, and are likely to slow down your computer more when they ARE clashing.
If you DO install more than one anti-malware program, the resident module(s) of ONLY ONE anti-malware program should be running at any one time - DISABLE the resident module(s) in all other anti-malware software.
Also, it's VERY wise to disable ALL resident modules of anti-malware software BEFORE you install software yourself.
NOTE that sometimes the resident module(s) of anti-malware programs - a part that runs all the time scanning for suspicious activity - will interfere with the proper installation of third party software, the software will not install properly, and you may get no indication of that at all while installing the software.
To avoid that possibilty, you should always DISABLE the resident module(s) of anti-malware programs, BEFORE you install third party software (software other than most Microsoft Updates, etc., that did not come with Windows ), especially when it's a major or complicated software package.
E.g. if you are using the free or paid version of AVG, you should disable the Resident Shield in AVG's 's settings in Windows. In Norton (Symantec) products, there may be several things you need to disable, or set so they don't load for a specific short amount of time.
If you don't know how to do that, tell us which anti-malware software you are using.
When you are sure the software has installed correctly, re-enable the resident module(s).
I have used the free versions of AVG software for years in 98SE, XP, and lately in Vista, and there's only been ONCE where I had to use a special AVG supplied program to remove it because it was corrupted and it's own un-install would not work .
ALL other times of the very few times it got corrupted I was able to use it's own un-install and when I installed it again it worked fine.
I never install more than one third party anti-malware program that has one or more resident module(s) on the systems I have or work on.
I often install the free version of Malwarebytes as a second anti-malware program, which does NOT have a resident module, at least not one that clashes with other anti-malware software. (The paid version DOES have a resident module.)
Whatever malware a Full scan done by AVG doesn't find, a Full scan done by Malwarebytes usually finds.
(The free version of Malwarebytes does not Update itself after it's initial installation - you need to select Update in the program and update it BEFORE you run a scan.)
In Windows Vista, and probably Windows 7 too, you have another complication - Microsoft's Windows Defender anti-malware software is built into it. It has a resident module that doesn't conflict with MOST other anti-malware software, but it DOES conflict with SOME third party anti-malware software.
Windows Defender can't be un-installed in Vista, and probably Windows 7 too, but it can be disabled from running in it's own settings.
When you install Microsoft Security Essentials, Windows Defender is automatically disabled from running if it's present, at least it is in Vista.
