Hi!
Last night I left my toshiba satellite L300 laptop on to run scans.I have Malwarebytes,Supera Antispyware,Comodo Registry Cleaner and Microsoft Security Essentials installed(all those were running at the same time,but that wasn’t a issue ever before).
In the evening I had also installed some new software from comodo’s site.I downloaded and installed comodo dragon,internet security,system cleaner,easy vpn,backup,disk encryption,secure email,antispam,antimalware,verification engine,time machine,cloud scanner and I also got their free email certificate(you can look up all those programs on their site if you want and here is the link if you want to do so http://www.comodo.com/products/free-products.php ).
I ‘m not quite sure what went wrong.I just thought it would be a good time to upgrade my security…
Everything was ok with the new programs installed,even after rebooting it.I was working on my computer and it was fine,so I decided to let the programs do the scanning overnight.After all,this wasn’t the first time.
So my old programs and the new Comodo Cloud Scanner were running.
In the morning I went to check if everything was alright.Supera had detected 3 or 4 threats(advertising cookies-nothing serious),Registry Cleaner had detected some problems with some keys and Cloud Scanner showed a message about an error that wouldn’t let it finish the scan.
So I quarantine the items Supera had enlisted(it wasn’t the first time,I had done it before),I delete the errors detected by Registry Cleaner(wasn’t the first time either) and i close the Cloud Scanner’s error window(the program was also closed at the same time).All three actions taken at that exact order.And immediately the computer shuts down.It showed a blue screen of death saying KERNEL….something I don’t remember….error,gave some microsoft advice about contacting admin or tech support,checking newly installed software or hardware etc,and then it gets stuck for at least 5-10 minutes showing the BSOD.So I press the reboot button.Nothing.It won’t shut down.So…I pulled the plug.I know it probably wasn’t the smartest move,but I really was desperate.
Then,I hit the on button,it opens showing a black screen with white letters saying microsoft windows cannot start properly.It gave me the following choices:start normally,start in safe mode/safe mode with basic programs(or something like that)/safe mode with command line and a last choice I hadn’t seen before starting at the last "secure" or something like that(meaning the pc running at the condition of the last time it started properly) for advanced users.I tried all these options-one at the time of course,but no luck.The screen also suggested using the vista installation cd and run fault repair.That last one I can’t do,cause my laptop came with vista preinstalled and no cd came with it.I was hoping I could use a restore point to make things better,or uninstall the programs(1st option is probably best),but I can’t even start it.
Any sugestions?Thanks in advance:-)
I forgot to mention that all my archives are in that computer and I don’t have any backup…
I trully apreciate your help!Does anybody have any idea how to recover my data?Preferably without paying…Thanks once again

"I can’t do,cause my laptop came with vista preinstalled and no cd came with it."

That’s nonsense.

RTFM: Read the PC User Manual to learn how to BURN your very own Vista Recovery disks. And, how to return your PC to "Factory New’ condition.

TIP: Never attempt to install new Security software while running your current Security software.
