There are a few typical indicators that could point to the presence of malware on your computer, be it viruses, trojans, adware, spyware, or another type of exploit. Even though malware is a vast category of software intended to harm and function against the user’s intention, casual users can quickly recognise the signs.
Ten Typical Computer Virus Symptoms
1. Despite being the only user on your computer, you haven’t made all of the changes.
Typical examples include noticing that your default language has changed, your default browser or search engine has changed, your favourite list has been added to your browser, your home page has changed, and so on.
2. Your computer slows down to a crawl and stops operating.
Slowdowns may indicate the presence of malware, particularly if you are not experiencing network problems, have not downloaded a large programme, and are not running numerous programmes simultaneously. You’re most likely infected if you check your task manager and see that numerous system resources are being consumed for activities you aren’t conducting.
3. A lot of pop-up windows start to appear.
Getting advertisements even while you are not using the internet is one of the more prevalent instances of infection. One particularly terrible type is a pop-up advertisement that claims your computer is contaminated and advises you to click on the phoney antivirus programme to protect it. Avoid clicking anywhere on this pop-up as it will just cause you additional problems. Instead, use your task manager to close the pop-up.
4. Files are altered or vanish.
Make sure you didn’t misfile anything first, but you are most likely infected if files are vanishing or if the authorship has changed. Should your files be visible to you but inaccessible, it could be a sign of ransomware – malevolent software that monopolises access unless you remit the demander (don’t do it, you still won’t get access). This is yet another compelling argument in favour of routinely backing up your files.
5. Your computer is unable to execute fundamental tasks.
Basic functions like a system that won’t boot up, won’t connect to the internet (or connects with a tonne of windows open to sites you didn’t go to), won’t perform basic functions, shuts down randomly, or does other strange things are examples of basic functions that are indicative of a malware infection.
6. An email is sent by your computer that you aren’t creating.
It’s likely that you are a botnet member and that you are infected. A software programme or script designed to carry out automatic tasks on command is called a bot. Attackers can remotely take over a compromised computer by using malicious bots. When a huge number of bots take over a large number of computers, they form what is called a “botnet,” which, when managed collectively, gives hackers enormous processing power.
7. The antivirus software you were using vanished.
If all of your security tools are inoperable or missing, you are most likely infected. In order to cause as much damage as possible without being stopped, many malware attacks first go for the security systems.
8. You are unable to launch or access your programmes, or selecting one icon opens an alternate window.
Malicious hackers frequently employ the tactic of coopting or rerouting user actions in order to carry out another, undesired action. It’s how they make sure they maintain control over your gadget or accomplish some other evil goal.
9. Entering the URL of a particular website directs you to a different page.
When you’re taken to a website that appears somewhat similar to the one you were hoping to visit, but not quite, it can be a very concerning indicator. Trojan viruses, which frequently start off as browser-based infections, frequently adopt this strategy.
10. Nothing seems wrong with your PC that you can see.
The previous nine factors are vital to look out for, but keep in mind that many malware programmes are made to remain unnoticed. It’s possible that you are infected without realising it.
Ways to Strengthen Your Computer’s Defence Against Malware
1. Make sure all of the updates, patches, and upgrades for your systems are installed.
Make the necessary changes to your operating system’s configuration to enable automatic updates. Visit the page for your operating system and follow the directions there to find out how.
2. Verify the version of your browsers.
Downloading the most recent versions is the simplest method. Get Firefox versions from this link. Get the latest versions of IE here. Versions of Google Chrome can be downloaded here.
3. Examine the security software on your PC.
It ought to have all the most recent upgrades, patches, and fixes installed. Check to check if you need to update your security programme by clicking on its icon. Install security software right away if it isn’t already installed.
4. Examine the security software on your phone.
You must install mobile security software if you’re using a smartphone. Unprotected phones are open to exploits, and mobile malware is here to stay.
5. Make your spam defences stronger.
This requires some ingenuity on your part and setting your email spam filters to a sufficiently high level. There are spam filters in every email programme. To locate yours, go to your settings and adjust these to a high setting. Just keep in mind to occasionally check your spam folder to see if any real emails have inadvertently ended up there. By typing the name of your email provider plus the term “spam filters,” you may also look for a step-by-step tutorial on how to set your spam filters.
Be aware of frauds, phishing, social engineering, and spam.
Attackers of spam and phishing schemes can reach us through a variety of channels, including your home mailbox (junk mail), your email inbox, instant messaging, social media, chat rooms, forums, websites, and, regrettably, your phone.
- You don’t have a wealthy, mysterious relative in a distant nation attempting to give you money. You are not the lottery winner. You won’t receive money from a stranger for any reason. There isn’t a single attractive woman waiting for your reply. An unsolicited pharmacy offer will only result in fraud or infection (on your computer or phone). If there truly existed a miracle weight loss remedy, every TV station and front page would be covering it.
- Reputable banks and businesses will never request that you “authenticate” your information online. Additionally, if you receive an email containing a link to one of these websites, don’t click on it. Instead, look for the website using your search engine, log in, and continue. The mail should be waiting for you in your account if it was genuine.
- If you are not sure who provided you attachments or what to download, don’t open them even though you are anticipating them. The prevalence of email account hacking has increased to the point where an email, link, or attachment that seems to be from a friend could instead be from a hacker who has seized control of your buddy’s account.
- Although following these precautions won’t ensure you never become a target of a fresh, aggressive malware exploit, they will keep you far safer.
