I have a Total Defense anti virus on my Windows 7 but my PC still infected with trojan virus.

Is there any free anti virus that can remove this?

Dear User,

There are many good antivirus programs which works fine in your PC, but yet unable to try and neutralize every threat.

I think almost every virus guard fail at some point.

But since you are asking for a virus guard which is free and considered to be good.

I would suggest you to use AVG 2015 free version.

Here is a link to it

Hello Julian,

It is very important to keep your antivirus program, and it’s database up to date in order to stay protected from latest virus attacks. So try to update your antivirus program and if possible set it to update automatically.

Scan your PC and now it might detect and remove the Trojan virus in your PC.

If your antivirus program still cannot detect it try Avast free antivirus. You can download it here

It uses streaming updates to keep the program up to date, and by default it will download updates daily when you connect to the internet.

Avast is the most popular antivirus program and you can upgrade to Avast Internet Security for sophisticated protection.

Maybe you don’t update your antivirus that’s why it can’t remove the Trojan virus on your computer. Just installing an antivirus is not enough to protect your machine from getting infected with a computer virus. It needs updating. When you install an antivirus, it uses a virus database that contains different virus signatures where it relies on detecting and recognizing a malware on a computer.

When an antivirus is installed, it comes with a virus database that is normally several months old or probably several years old if it is an old version. At this point, the antivirus will only recognize viruses that were identified when the virus database was created. It won’t be able to recognize viruses that were identified passed its creation date.

That means from that point onwards up to the present, malwares will be invisible to the antivirus. Unless the antivirus is updated, your computer will be vulnerable to virus infection and other malware attacks. If you are sure that your computer is infected with a Trojan virus, download and install Sophos Virus Removal Tool. Take note, this is not an antivirus and it will not protect your computer from a virus because it doesn’t have a real-time protection in effect.

It is only a tool for removing malwares on the computer. It is best used on computers that are already infected. You don’t need to uninstall your current antivirus. It works alongside any antivirus program you may have. When installing Sophos on your computer, don’t disconnect from the internet. At some point of the installation, the setup wizard automatically updates the virus database.

Once the installation is finished, begin scanning. At the end of the scan, remove all found viruses and restart scanning. Repeat scanning until it no longer detects a virus.
