Mr Bruce 1959 has suggested I re-post my problem here so here goes:
A few weeks ago I started to download DVDShrink from what looked like a perfectly legitimate company site. After I clicked to download the program it began instead to install itself. At the same time all kinds of alarms went off - Comodo, Malwarebytes, etc. - and I quickly shut down.
After booting up I ran a quick Mbam scan and it found 32 infected files which I deleted. I then ran a full Mbam scan and it found a bunch more. Later I also ran full Mbam and Avast scans but this time around neither came up with anything.
For a few days everything ran OK but then Firefox began to freeze up whenever I brought up a web page with a Youtube video on it. Then other things started to freeze - Task Manager, etc. - and now it's reached the stage that the computer won't boot. The computer won't even start in Safe Mode. At best it just brings up my mouse pointer (which works) and the Windows Welcome screen but nothing more.
Different Windows messages have appeared at times one of which said something to the effect that Windows was stopping to prevent further damage. There is a separate RECOVERY partition on the D drive for restoring the computer to factory settings but I can't access it.
Pressing the F keys on startup bring up the following screens while pressing the ESC key on startup brings up a menu listing all five of these options::
F1 - System Information
F2 - Advanced System Diagnostics
F9 - Boot Manager with 3 options:
1. Hard Drive;
2. CD/DVD Rom Drive;
3. Network Adapter.
I shifted to #2 and booted but the only disc I have is a Win 7 System Repair Boot Disc. This kicked in, started running, and then fizzled out.
F10 - BIOS Setup
F11 - System Recovery. This gives 2 options:
1. Start Windows Normally;
2. Launch Startup Repair.
I've run both of these many times and always with the same result - they fizzle out leaving the Windows welcome screen + mouse pointer or sometimes just a blank screen.
Any advice members could offer would be greatly appreciated.
Here is a link to my earlier topic about this problem so you'll know what has already been tried:
