Win32 Viruses are Trojans, but they are quite old and fairly harmless. It is the type of virus that automatically attaches itself to a file to modify it. This results in your outgoing emails showing an image of a fireworks display. It is actually quite cheerful!
This virus was started in 2005, so as viruses go they are quite old, they enter your system on an incoming mail with an attached. Exe file. If you open this file, it activates the virus and while it does not actually harm your data or computer they are not good to have. No virus is and it should be removed. This can be done manually or with anti virus tools.
Perhaps more commonly known as the. Happy99. Exe can also attach itself to news groups, and the person who sent it to you rarely knows that they did this. What it does after you opening it up, besides causing a fireworks display, is create 2 files in your computer, these are in the system folder. They are easily found, and for your reference these are "SKA. EXE and SKA. DLL."
Two files are created in the system folder, the SKA. EXE & SKA. DLL. Files. One modifies your files and the other allows the virus to do its work. Effectively it kind of mutates and turns into another version of the file and happily attaches itself to your outgoing mails that you spread it unawares.
Just like all viruses and all Trojans, Win32 is a sneaky little "b", and although it is not nearly as harmful to your equipment and won't crash your computer, ruin programs or allow anyone to view your private information it can cause a mail server to become overloaded. As it attaches itself to newsgroups, if the email lists are very long, it can clog up a server for what seems like an eternity.
Other viruses are able to attach themselves to the Win32, and this is when things can get dangerous. This happens because Win32 moves around all the time, with many people hardly knowing of its existence.
It is relatively simple to remove this virus, even without anti-virus software tools. You just do it through DOS. You remember DOS don't you? But then again perhaps you don't but you will find instructions online. If you have seen fireworks displays going off when you send out emails, your PC is contagious and has the virus, and you don't want to pass it onto other users.
Although Trojans like Win32 are supposed to be harmless they may still allow third parties access to your most sensitive information, so they must be gotten rid of. They almost always mutate, so better be safe than sorry.
