How to delete a trojan? [SOLVED]

post #1 of 19
Thread Starter 
My friend has a trojan in his comp. that wont let me open anything. For example I when I try to open Command prompt (cmd) it says virus and then a window pops up saying to scan my computer, and it does that for everything I try to open.

I know its just 1 program causing this, so how would I go about deleting it?

Do you have the recovery discs for the computer? If so, put them in and they will erased everything like new again. Otherwise, you can replace the hardrive. that also means installing a new operating system, which your recovery discs might be useful as well.

wow you sound like dell support:

noob: "my pc won't boot"
dell consultant: "reformat it"

there are many thing to try before reformatting. that is a last resort.
try booting into 'safe mode with networking' and dling and installing/running malwarebytes.

First boot into safemode (hold down f8 at boot, as im sure you know) and see if you can run .exe normally in there.

Why, oh, why do (lots-of) people insist that wipe/re-install is the solution to a virus/trojan?

Sure... it is quick (sometimes)
Sure... it mostly always works

Conversely;
Sure... you learn nothing of exploits/exploit-methods/prevention
Sure... I just LOVE to reinstall an OS including drivers, AV, specialist-software etc. (FFS I have over 0.75TB of vst/vst3/soundbanks/etc.)

OP - Whatever you do to attempt removal, do it in Safe-Mode

You wouldn't BELIEVE (actually... you probably would, lol) the amount of *cough*tech professionals who would recommend the reformat at the first chance. LAZY bar-stewards!

And, as last words of advice;

disable restore points

Best way is just reinstall, especially if it's windows7, takes no time really does it

Try safe mode with networking, and have malwareantibytes on a cd. Install, update, and preform multiple (2) full scans.

Sounds like you got 'you got a virus' virus !

Once or twice it tried to get into my comp and McAfee (for its hogness) gave it a good nice boot.

Anyway, if I recall, this virus is smart enough to disable your anti-virus. I think one way to fix this is take your HDD out and hook it to another comp that has a robust anti-virus and then try to scan your infected HDD.

My sister just had this virus on her laptop, the fake anti-virus right? No matter how many times I booted into safe mode and ran malwarebytes, it still wouldn't get rid of it. What finally worked was logging into a different users account(if he only has his, then use the administrator account), and install microsoft security essentials. Once that has been installed, run a scan and it should pick it up.
