URL:Mal is an Avast detection of malicious websites that may infect your computer with malware. If you got this warning once and your anti-virus blocked it then everything should be fine. However, if you are constantly getting Infection URL:Mal pop-ups then your computer might be already infected with malware, most likely a Trojan horse (Trojan.Agent or Trojan.Tracur) that either attempts to download additional malware files on your computer or tries to connect a command and control server in order to report some kind of information about your computer. It could be even sensitive information, your passwords for instance, in case the Trojan horse also has spyware modules. One way or another, you need to remove it from your computer as soon as possible. Otherwise, you will keep getting URL:Mal infection pop-ups and most importantly, your computer will be wide open for cyber crooks. Besides, if your anti-virus can't handle this infection then you obviously will have to use additional tools to remove the infection. For more details, please follow the steps in the removal guide below.
OK, so you may have heard of Trojan horses but if you're not quite sure what they are and how they affect you and your computer, read on as we take a closer look. The first thing you need to know is that if your PC has been infected, you may well be at fault. URL:Mal infection blocked pop-up is usually a good indicator that a Trojan horse is active. At least, you have had a part to play in the process. I hear you – surely no one would knowingly infect their own computer with malware, but that's where Trojan horses get sneaky. In order for a Trojan to infect your computer you have to install the application's server function. And this is how the software gets its name; from Greek mythology where the ancient Greeks infiltrated the city of Troy by hiding their army in the belly of a giant wooden horse. This is how modern day Trojan horses work too as they convince you that they're legitimate programs that have nothing wrong with them. This is known as social engineering.
A Trojan horse may be sent to you by a spammer in an email. Open the email click the enclosed attachment and boom – you've just installed the Trojan on your machine by running the .exe file. This common method is employed by the creators of Trojans as, unlike viruses, Trojans don't replicate themselves – they rely on you to do their dirty work by executing them yourself. After execution and installation are complete the server linked to the Trojan will launch automatically each time you log on. And as a result, you may get URL:Mal pop-up on every startup.
You may also install a Trojan horse or some other kind of malware if you've downloaded a program that has been designed to look like the latest must-have software – but it will be disguised as something that has a Trojan attached - another instance of social engineering.
Trojan horses are definitely something you want to avoid at all costs and you shouldn't be fooled into thinking they won't cause you any problems just because they're not technically a virus. Trojans are still malicious software, and they are an unpleasant one at that. Trojan horses can unleash a whole world of pain on your computer, your hard drive and your files by corrupting your data and make it impossible to access. Just imagine the nightmare of not being open any of your files or documents. As I said, Trojan are very often installed with spyware modules that can steal your passwords and credit card information.
Thankfully there are a number of precautions you can take. From making sure you have reputable – and bang up to date – anti-virus and anti-malware programs installed on your machine, to never opening emails if you don't recognize the sender. Should you open such an email by mistake please, please don't open any attachments! Simply delete the mail. Then, don't visit shady websites and don't download files from dodgy, unreliable sites.
