I'm usually ok getting rid of trojans, viruses etc. and yesterday I got a laptop running for someone I know, with help from ERD 5.0, that wouldn't boot, and had 0k free space. Once the laptop was booting up, I downloaded ccleaner, using my own laptop, onto a usb drive, plugged it into the other laptop, and ran the setup. The idea was to free up some space on the C: drive. Ccleaner setup ran for about 5 seconds then closed down before it was installed.

I tried to download it after making some space on the now-working laptop, but I got a message saying "Use internet explorer you dope".

I put the usb \ pen drive into my (normally) bullet proof laptop, where Bitdefender always 'sees' the drive and says"Usb drive detected. Do you want to scan for viruses" or something similar. The message didn't appear, and the Bitdefender icon went grey.

After some googling, running Bitdefender Online Scan, Superantispyware and MalwareBytes Antimalware, it turned out I'd picked up 'killer.exe' plus 'funny ust scandal virus.avi.exe' plus 'win32.sality.og' plus 'worm.io.35163' plus 'trojan.autorun.nd' plus 'executes c:\smss.exe'

Bitdefender managed to upload them to their lab but not heard back yet.

The 2 antimalware progs found them but rebooted before I had a chance to check what Startup Monitor was telling me. I'm guessing that they needed permission to delete what they'd found on bootup, but the reboot kicked in before I could read the mesage

The problems I currently have are :

Task manager is disabled

Regedit is disabled

Command prompt won't find any programs (ie DEL) so I can't manually delete the malware found by my protection software

Bitdefender is disabled

The bitdefender help and forum websites seem to be blocked as they won't load

Bitdefender online scan, which is usually available as part of Firefox, is disabled

All Firefox add-ons (No script etc) are disabled

If I run ccleaner, something shuts it off after about 5 seconds, but I can run anti-malware software which is strange

I get a blue screen if I try to boot into Safe Mode, and the laptop instantly reboots just after

I ran ComboFix which deleted autorun.inf and some other unwanted bits, but I still have all the above problems

My cd drive isn't working, so I can't boot from cd

If I click on a link to a website in a Google search I get redirected to printer sites (Epson, Hp etc)

I'd appreciate any help, and I'm quite geeky so will understand any instructions thrown at me

Thanks ;)

Is there anyone who knows how to fix these please ? ? ?

I also get Firefox redirections like the post below, and the bsod if I start in Safe mode. I ran superantispyware and mbam but they get shut down just before they remove the malware :thumbsup:

I also tried to view hidden files and folders but whatevers on my pc won't let me 'apply' so it reverts to hidden.

Plus my C: drive has an unsual icon now : A windows symbol on top of a blue \ grey hard drive.

I know this site is busy with previous requests, so while I'm waiting I tried to goto trendmicro's online scanner and pctools for the same reason, but both seem to be blocked by something as Firefox doesn't load the pages.
