– Run anti-virus, it can delete or isolate the file so it can’t get in contact with other files
– Deleting the file directly in windows explorer usually doesn’t work
– Most programs not active when in safe mode, try deleting from there
Here are a few things to look out for if you are suspicious whether your computer is infected with a computer virus:
- Processing Speed : Computer virus tends to overload your computer’s task manager with a load of different programs which could cause your computer’s speed to dramatically slow down. Generally, the processes shown in your task manager would not go above 10% of your computer’s usage. You can check this by holding down the CTRL key and the ALT key and then pressing the DEL key. Select the Task Manager button in the options provided. It would provide a pop up menu. The computer usage percentage is located on the lower left side of the pop up menu. If the usage is at least 50% or higher, chances are your computer has been infected with a computer virus.
- Missing Files : This is perhaps the most common sign that your computer is infected with a computer virus. Many computer virus that have been developed and are now going around the Internet have been made to actually delete some of your files in random. This would eventually cause many of the files and programs in your computer to allow your operating system to be deleted, causing you being unable to log in and use your computer.
- Error Messages : Error messages that suddenly spring up when you are trying to access programs that you have long been using is a strong tell-tale sign that your computer is infected as these error messages would often come up if the program has been corrupted.
Firstly, the most effective and important way to deal with most dangerous viruses is the avoidance or awareness of pitfalls. Most lethal viruses have to find a way to get to the computer with the users permission, whith our without the intent of the user. They mostly try to make the user think they are allowing permission for something else, such as access to a website. In other words tricking the user. One example, a virus preteding to be an antivirus should be easily spotted. All professional antiviruses have distinct visuals. Viruses acting as antiviruses would have minimum colouring and look like a simple alert window, like this:
