I have a trojan horse it looks like this PSW.x-Vir trojan horse. How do I get rid of this troublesome thing?

Answer 1

FREE TOOLS ON LINK

Answer 2

How do you know you are infected with that specific Trojan Horse? If you have an antivirus program then your best bet is to use it to remove it. If that should fail, there are a number of antivirus programs which are fairly good at removing some Trojan Horses. You can use BitDefender Antivirus free edition. It doesn't offer any real time protection but its on demand scans are very good and the program removes most Trojan Horses. The link is http://www.filehippo.com/download_bitdefender/

Another option is to use a standalone anti Trojan security program. The best free program I have come across is AVG Antispyware. Don't be misled by the name, it was originally called Ewido Anti Malware before it was bought by Grisoft and had a name change. It is one of the best Trojan scanner and remover. The download link is http://www.filehippo.com/download_ewido/

Download the security software and install it on your computer. Next, update them and then run scans. Be sure to quarantine any suspicious files detected.

Answer 3

You cannot rid of that thing using ordinary AntiVirus tools. You need to edit registry. Its in the Registry as a SelfHeal, so it will reinstall upon computer start up. Go to Start Run, Type in regedit and then HKey_Users\software\microsoft\sindows
current version internet settings Z

Find it in there and click on the "change its name" For exampleif its 1004, change to 1003. Reboot It will be gone.
