Malware is short for malicious software, software intended to harm your computer. Generally, people call malware viruses. This isn’t exactly incorrect, but it’s not accurate. All viruses are malware, but all malware are not viruses. Already infected? To remove malware, we offer a Virus Removal and Computer Tuneup services. There are various types of malware: worms, trojans, spyware, rootkits etc. While they act differently, overall, their intention is to harm your computer.
Viruses are self replicating and can corrupt, modify or delete files. They attach themselves to files and are initiated once a user opens or installs them.
Pretends to be legitimate software but does harm in the background. We see computers with trojans often. If you recently downloaded a sofware that claimed that you had 1000 viruses/errors on your computer and you should scan now to remove them — guess what? — that’s a trojan. That software pretended to be an antivirus, when in fact it is not.
Worms propagate through your network connection to spread itself. They are different form viruses because they are standalone malware and don’t attach themselves to files. Worms attack software vulnerabilities or “holes.” Keep your operating system and application software updated.
Adware (added software) is software added through the installation of another software, while spyware spies on user activities. Sometimes they don’t fit neatly into one category. For example, a spyware could be an adware.
If your computer is displaying erratic popup ads, you might have spyware. Spyware mostly acts without your consent. They monitor your web activities, collect your data and send that information to a third party. This third party can sometimes be malicious. Spyware can also be harmless tracking cookies that display ads of items you previously searched for, for eg. Google Ads. They can also be harmful keyloggers that record your keystrokes such as your email login and banking information etc.
Rootkits are stealth operators of the malware world. They invade your system and gain administrator privilege and run in the background. You could have a rootkit for years and not know it. A best practice with a rootkit infection is a wipe and reload, or Operating System Install. If you think you have a rootkit, you can try Malwarebytes Anti-rootkit removal tool.
Bloatware/Potentially Unwanted Programs (PUP)
These are software that use system resources and offer little to no value to your system. They just occupy space, hence the name “bloatware.” These include pre-installed software and toolbars.
There are many types of malware and their intention is to harm your computer. A general understanding of what you have will help you (if you are a do it yourselfer), or a technician to resolve a computer problem.
