Effects of Malware
Malware is malicious software. Some types of malware include viruses, spyware, and trojans. Malware is one of the biggest threats to computers in the modern day. A virus can attack anything in a PC, for example, a browser by redirecting any search term. It can track the sites that you visit, source unwanted pop-up ads, or any other related inconvenience. Also since malware is often not programmed competently, it can slow down the speed of a PC significantly.
Malware often re-installs itself even after you remove them from your PC, sometimes they hide deep into windows program, thereby making it impossible to clean up. There are diverse vaieties of malware along with preventive measures that you can take to save yourself from getting infected.
Although there are so many ways a PC can get viruses, the most common way results from programs being download and installed whether you did so intentionally or not. For example one way they can be installed is by accidentally clicking pop-up ads, which then redirects you to the program download. When an unanticipated website popup occurs that requests the installation of an application, this application is often times malware. Additionally, internet explorer also has many vulnerabilities which viruses often take advantage of to install malware on the users computer without their knowledge.
It is easier to infect a PC with malware than it is to remove the infection. Can Antivirus software detect malware? For a long time, antivirus engines have been fighting against malware by consistently releasing updates in order to combat the new creations of malware providers. While some AV’s provide protection against well known malware, newer malware still often evades the AV without any detection at all.
If you want to prevent getting infected from malware, it is better to periodically scan your computer with an anti-malware solution such as Malwarebytes rather than use an antivirus. Antivirus software do not do a very good job removing newer malware or even variations of the same old malware. It is also common practice for malware authors to FUD or undetect their malware from common AV’s to prevent detection. Sometimes they will do this manually or will use an fud crypter to do this.
Other types of malware
There are many types of malware and each type of malware is often categorized in one of the following categories: spyware, hijackers, adware, trojans, backdoors, RATs, keyloggers, bootkits, rootkits, and stealers. The general term that classifies all of these types of categories is “malware”, which basically means “malicious software”. In fact, in hacking forums or security blogs, often use words such as malware, viruses, adware and spyware interchangeably even though they are sometimes inaccurately used in the context.
Adware and spyware – these type of malware specifically source ads on your screen. These ads can be in the form of embedded into websites, pop-ups, or pop-unders. It will depend on how the author wants to display the website. This type of malware is often less harmless then it is an annoyance unless it effectively obtains personally identifiable information for third parties, in which case, it could be quite dangerous.
