I can’t get rid of  a Trojan virus on my computer. Yesterday I was playing a game and then AVG said Trojan horse TDSS.CA was detected on my computer. However, AVG didn’t allow me to remove it. Is there any other way I can remove this virus completely?

AVG Keeps Reporting Trojan horse TDSS.CA Virus?

Now thousands of AVG users are currently facing to the Trojan horse TDSS.CA virus detection and have no idea to remove it. It is a malicious Trojan dropper which can add malicious or potentially unwanted software to your computer without your permission. Users always get infected with this virus from  free software, games and media players that means it gets installed automatically while the users download some unsafe resources.

Although a Trojan does not replicate like a Worm, it installs a backdoor which allows remote, surreptitious access to infected systems. Once it is running in your PC, it can be used by remote attackers to upload and install further malicious or potentially unwanted software on the system. The virus is able to escape most antivirus detection because the running process is a valid Windows component. However, if users have installed AVG on the infected PC, it can be used to detect this stubborn virus. Though AVG can detect Trojan horse TDSS.CA Virus, you still cannot feel relax because it doesn’t allow you to remove the virus at all. Every time when you attempt to delete this Trojan, you only get two options which are “Protect me” and “Ignore threat.” Neither of them are working to remove this threat from the computer.

As malicious as other Trojan viruses, it can gather your confidential information such as password, credit card details, revenue details and others without your knowledge and then transfer to attackers for illegal use. Worse still, it may monitor web-browsing activity of the user and redirect users to all kinds of ad sites against their wills. Considering a Trojan horse is extremely dangerous because it can be used to record personal information on your computer and communicate it to a remote hacker, it is important to remove this Trojan manually from your computer as soon as possible.

Note: Manual Removal requires expertise and it is for advanced users, if you don’t have much experience in dealing with redirect virus. Contact YooSecurity Online PC Experts for removal assistance.
