What to do if my computer is infected by a virus or a malware?

I think my PC might be infected. Whenever I try to install Kaspersky it says it can't install because the PC may be infected, and that I need to first install the Virus Removal Tool.

I've also tried to install Microsoft Security Essentials but it says I'm not able to because Windows Defender is running - I should turn it off first before continuing to install MSE. However I don't seem to be able to turn it off; my PC is running in safe mode with networking.

What should I do to start Windows normally? Is there any solution or do I need to format the C: drive? My audio device is not working and Adobe as well.

Which antivirus should I use to avoid any problems in the future - is only having an antivirus sufficient, or I should also install a firewall, virus removal tool, etc?

You should always have an antivirus tool installed prefereably before connecting too the internet. While this isn't always ideal you can always keep a copy of A/V on disc or USB. I would reccomend an anti virus coupled with windows firewall and a spyware removed such as super anti spyware.

If you are sure that you have a virus then maybe you can download and burn a bootable antivirus disc which will boot you into a linux console that scan for viruses and usually removes them.

Kapersy Antivirus Boot Disk

Be sure to make this disc on a PC that is Not infected.

Download and install MalwareBytes Anti Malware , Install, update the definitions and run a system scan, this should be able to pick up what's troubling you. Then restart your system and install an antivirus.

I do choose the Free Trinity : Avast - Malwarebyte's Antimalware - Superantispyware (you can easily download and install them all from www.ninite.com)

Avast works great as a shield for normal use. When you get any kind of infection sign a compete scan with the other 2 will give you almost 100% sureness to be clean again.

To save your infected pc I suggest you to use a MiniPE cd or Linux Live CD and start an antivirus from there.

If your pc can start but can't install any software you could also give Dr. Web Cure IT a try: it's a portable app (no need to install) and it saved me many times :)

Also try Stinger, which is available from here (it's free and is designed to remove remove viruses that are actively trying to block Anti-Virus and Anti-SpyWare software):

  McAfee Stringer - free live Stealth Virus removal tool
  http://vil.nai.com/vil/stinger/

  Link to Stinger with a short introduction
  http://www.lumbercartel.ca/resources/security.pl#stinger

It's a specialist in getting certain stealth viruses only, and is not a replacement for a regular Anti-Virus tool that scans for all types of viruses. It also doesn't require any installation as it's a stand-alone program that just runs.

This one has been useful to me quite a few times over the years. Since it doesn't include an automatic updater, always make sure you're using the most recent download of it before running it.
