A virus attaches itself to an existing program such that, when that program is executed, bad things happen. Like a biological virus, it cannot live without a host. In contrast, a worm is an independent program that reproduces itself without requiring a host program.
Depending on the form, a worm may be able to propagate without any action on the victim's part. Most malicious software today consists of worms rather than viruses.
Worms and viruses require slightly different protection mechanisms because of their different propagation methods. A virus scanner operates by searching for the signatures of known viruses. A signature is a characteristic pattern that occurs in every copy of a virus. It might be a string of characters, such as a message that the virus will display on the screen when activated, or it might be binary computer code or even a particular bit of data that is embedded in the virus.
These patterns are identified by technicians at organizations specializing in computer security and are then made available on security Web sites. Virus scanners can then download the patterns to bring their internal pattern lists up to date.
There are three complications with this scheme. This has all to do with the user-friendliness of the program and the options available with virus scanner. Have you run into a problem? Is your antivirus software not responding as it should?
If that is the case, it can be very helpful to have a support team available that can quickly and efficiently answer your questions and help solve any issues. Some antivirus software developers offer support, others do not. Of those that offer support, some offer a live chat, while others only offer email support. The latter can increase the waiting period. Be mindful of what you prefer and take this into consideration. Every virus scanner tries to differentiate itself from its competitors.
They do this, among other things, by offering extra options. In addition to a virus scanner, they also offer a password manager , for example, or protection against phishing scams. Others offer you cloud backup space when you purchase a subscription, or give you a discount on a VPN service.
In addition to these extra options, the ability to precisely adjust the settings can also make a difference. A novice user probably wants to get started as soon as possible. An advanced and more technical user, on the other hand, will like the benefits manual configuration has to offer. Of course, the price of your antivirus software is also an important factor. Ideally, you want to protect your devices as optimally as possible without having to pay too much for what you need.
You could consider freeware or opt for more security with a paid virus scanner. As we discussed earlier, some free virus scanners work quite well, but they do come with some risks you need to be aware of. While you are probably not able to or capable of testing different virus scanners, others are. You can find numerous reviews online. On Google Play, for example, people often rate the apps they download.
Sometimes they include comments, which can be a very useful source of more details. On forums such as Tweakers, technical users discuss the effectiveness of specific virus scanners.

Do you want to install antivirus software on your device? This is how you do it quickly and easily:. A proper virus scanner will protect your device against most types of malware.
In this way, it is much less likely that computer viruses, keyloggers, or spyware will become active on your device. However, there are more online risks. So, what else can you do to protect yourself online?
Many people schedule their full scans to run at night, find a time that works for you. Persistent malware is a major reason for using multiple scan types. In the old days, computer viruses and malware were "one and done," meaning that they were discovered, cleaned up, and then you were done with it. Modern-day malware is persistent, capable of hiding in registries or startup services, and capable of re-infecting the computer on reboot if the malware isn't completely eradicated.
So, part of running a scan is being prepared for persistent malware and understanding how best to combat it.
With that in mind, here are some tips to consider:. Also, set up future automatic virus scans. Don't stop at a single full scan. It's important to maintain a schedule of routine scans to ensure your computer is always protected.
Be sure to manage your scheduled scan settings. Follow-up scans will require you to read the reports and take action as well. If you stay attentive to your software, it will usually walk you through the process in seconds. The preparation and scan steps listed above will generally cover most of your virus scan needs.
However, you might find that virus scanning is not the same across each of your devices. Here are the common differences you might experience between device types:. How to run the software: Your antivirus should be set to run on system startup by default. It will continue running from the system tray even if you close the window.
Authorizing permissions: Antivirus software will likely need administrative permissions to run properly. If your computer has multiple users or is managed by an IT team, installation and operation must be approved by your admin.
Be sure to download the appropriate software for your OS version. How to run the software: Like on Windows 10, initial installation should get your antivirus to run in the background on startup. Most software should be a set-and-forget setup. Authorizing permissions: Again, administrator privileges are usually needed to install and run antivirus programs. Where to download: Most common antivirus software on Android will install from the native official app store, Google Play Store.
Apps like Kaspersky Internet Security for Android download directly from the store and are ready-to-use once installed.
How to run the software: Antivirus mobile apps run automatically just like those on computers for Windows 10 and Mac. Some apps may only offer automatic scanning in their premium versions, so be sure to upgrade for the best protection.
