Extreme Virus





Denvis
My mate caught a virus that didn't allow him to open control panel, command-line, registry editor, unable to install/uninstall applications, system restore. The virus doesn't even let him format his computer. There are literally pop-ups every 5 seconds and unable to access the internet.

What are other possible ways of solving this problem? I'm out of ideas. I don't want him to fork out coin to fix a silly virus but I don't know how to fix it. Confused

boot up in safe mode

Try Safe Mode first.
Press F8 when the computer is starting up, and choose safe mode.

Then do a system restore.
If safe mode doesn't work, then the option would be to reinstall Windows, ideally after a full format also.

Safe mode. What I fool I am. Thanks. Can somebody explain the main differences between starting windows in safe mode opposed to just normal?

Safe mode only loads the bare minimum needed to do things on windows, and won't run any additional software that could otherwise run on a normal bootup (let's say a virus).

You will of course need to find the source of the issue.

Once booted in Safe Mode, remove any previously installed programs or files. If you see anything suspicious, I'd remove it. Only if you know what you're doing though. Some files are needed for the computer to operate, so deleting those files may just cause you more trouble.

But I'd try to save the important data from the computer and then just do a fresh install. Seems a computer is never the same once it gets a virus until it gets a full reinstall again.

that's because most people that remove it by hand don't remove all of it.
if you removed all of the things the virus edited, you won't notice any difference except the psychological effect of thinking every minor issue was caused by that virus.

If the virus has infected your system files which logically, would be the first few files they are normally designed to attack. Chances are, you won't be able to delete them as stated by ghost rider "some files are needed for the computer to operate".I agree, a computer is never the same once it gets a virus, however if you remove it before it does too much damage then the user may feel that it's the same.

In my opinion. The instant a user's anti-virus software detects a virus the user instantly feels like the computer has slowed down, regardless if it's only a key generator. People are made to think, oh my anti-virus has detected a virus there HAS TO BE SOMETHING WRONG and then the user becomes paranoid. Most of the time there is a virus but once the virus is removed, some people think that it's still there and your system isn't as fast or as efficient as it once was, even though it is.

How are thing's going in safe mode?

Typically, the first thing I usually do is boot in safe mode and try to install a quick anti-malware program, Malwarebytes is quite effective, and do a quick scan. That may get rid of a lot of the stuff that's generating the pop-ups every 5 seconds. If a good number of infected items were removed, then you can try to boot in regular mode again and see if the computer is doing better. You can also do another quick scan since everything is now loaded as opposed to the bare minimum in safe mode.

i've encountered the same problem with one of the PC in our work site. Worst thing is it doesn't even allow me to boot on safe mode. What it does is it restart the system if i choose safe mode or last known good configuration. Last thing i did was to take out the Hard disk and plugged it on another pC and had it scanned, had it fixed.

do you have run command? if not, create a batch file on notepad do the following:

type cmd on the first line and save it as "dos.bat" on your desktop.

then run it. it should open your dos.

if you like troubleshooting more, we can still suggest more options but if you don't have much time,

Take out that hard disk and buy a hard rive enclosure then plug it on another PC then scan it. then back up your documents then reformat if you want to have a new installation,


tell us if you are successful or not. Good luck.

My mate managed to install the latest version of Windows 7 after, god knows how many tries. I will definitely try out safe mode, creating a batch file and a lot more other troubleshooting methods the next time (knowing my mate, there's always going to be a next time).

otherwise install linux. xD
