Tip & How-To about Computers & Internet

Removing a BAD virus infection

Your computer won't start up without lots of things going wrong. Your antivirus (AV) program tells you there are 1000s of infected files, or it won't update, or won't even run. How do you get rid of a nasty infection like this?

Please read this entire article before doing anything, and if you feel lost, DON'T proceed, find someone who knows what I'm talking about. This will be better than destroying your drive or your friend's computer!

You're going to need some things:

  • a good friend who'll let you use their computer (and drive case), unless you have a second machine
  • a second computer, working perfectly with a good, up-to-date AV program (anti-malware would be a plus too)
  • an external USB drive case to put your hard drive in, or be able to plug the drive inside the second computer (in a desktop only)

If you have access to a USB drive case the right size for your drive, mount the drive in the case. You can then plug this in to the good computer.

If you don't have a drive case, you'll need to open the good desktop up and connect your drive to the second drive cable. The boot hard drive must stay there of course, on its own drive cable. You'll need to disconnect the CD/DVD drive to do this, and any other drive connected to that second cable, so that your drive is the only one on that cable. You'll need power for your drive as well, of course.

To run a virus check you can usually right-click on the drive in My Computer or similar, and select a virus scan from the menu, like the example with AVG below.

This scan will take a while. Set to full speed scan if your AV program allows this, and let it go. When this has finished, remove all the infected files listed. Run the anti-malware program as well. If you think it necessary, run them both again!

While you've still got the drive in the other computer, and AFTER you're sure it's clean, back up any important documents to the drive on the other computer (and then check them again for viruses!).

When this has all finished, shut down the computer and put your drive back in its own computer. If you're lucky, it will actually boot, but this may not be the case. You may need to repair/reinstall Windows on your drive, as some of the files quarantined or deleted may have been system files.

Now you know the value of having a working AV program, don't ever operate without one again, and always keep it up-to-date.

I have windows os and there is a autorun.inf something hidden file in my all drives.my avira antivirus has blocked that file.and i want to know that is the file safe or it is going to harm my pc.what should i do?

Autorun.inf is the primary instruction file associated with the Autorun function. Autorun.inf itself is a simple text-based configuration file that tells the operating system which executable to start, which icon to use, and which additional menu commands to make available. In other words, autorun.inf tells Windows how to deal open the presentation and treat the contents of the CD.

That being said, it would depend on what it is trying to run automatically. If it is trying to run iTunes automatically that is one thing, but if it is running a virus automatically it would not be safe.

You can right click on the file, and edit it with notepad/wordpad to find out what program it is trying to run.

The only thing that comes up is a Red Cross Antivirus window, cant seem to remove it. I already have an antivirus downloaded.

Red Cross Antivirus is a rogue anti-virus program that is installed via the Fake Microsoft Security Essentials Alert Trojan. This rogue is installed via a fake Microsoft Security Essentials alert that states you are infected and then prompts you to install 1 of 5 rogues, including Red Cross Antivirus. When the program is installed it will reboot your computer and start before you see the Windows desktop. It will then scan your computer and state that there are numerous infected files found, but will state that it will not be able to clean some of them as it requires the heuristics module in order fix them. In order to activate this heuristic module you will need to first purchase the program. This is a scam, though, as none of the files it states are viruses are actually infected.
Go to TrendMicro.com and run a free online virus scan to eliminate this rogue.
