Have you ever wondered why your computer is making a strange noise and acting slow? Or it's not acting up, but you're sure something is wrong. Don't wait until your computer becomes permanently damaged; it's time to get rid of that virus! But before we can do that, we need to know exactly what's going on inside your machine. So here are five common signs your computer has a virus:

Slow Performance

Multiple things can cause a slow computer, but even the most basic of tasks can already be enough to slow down your computer if it's infested with a virus. So how do you check if your computer really is infected with a virus? Try running an antivirus program on your machine. If any files are corrupted or deleted when scanning, then that could indicate that there is indeed something wrong with your operating system or hardware components (hard drives). It'll also help to check the RAM (random access memory) usage of each application running at all times, especially important when using graphic-intensive programs such as games and photo editors – this will help identify any potential problems before they become bigger ones!

Pop-up Windows and Suspicious Emails

Pop-up windows are heavily notorious for tricking users into unknowingly downloading malware onto their otherwise healthy computers. For example, you might receive a pop-up notification that says your computer is at risk of being infected with malware or that you should update the software immediately because it's outdated. The virus may not be able to infect your computer if you have antivirus software installed on your system, but it can still spread through other means, such as web browsing or opening files from suspicious emails. Sometimes even just a simple click on the wrong link can damage your computer, causing it to become slow or even completely stop working altogether! The best way to avoid this is to never click on any suspicious links or ads and only check emails from people or companies you know and trust.

You Can't Download Antivirus Programs

If you're looking to download an antivirus program but can't find or install one, that's a clue that your computer has already been infected with malware. It could also mean that the virus is "hijacking" (taking over) some other part of your computer, such as its security software or operating system. So, if you can't download any antivirus programs from official websites—and even if they are available from lesser-known websites—your best bet is to contact tech support and have them remove the infection from inside your machine before installing new software.

There's A Sudden Lack of Storage Space

If you have a virus, it can consume your hard drive space. When this happens, the virus will delete or move any files you have stored on your computer. This means that everything is at risk of being compromised and lost forever! Always be sure to back up your computer regularly and delete duplicate or unnecessary files to free up space. It's better to nip it in the bud and use an antivirus program or bring it to a technician once you see any form of suspicious activity going on.

Constant Crashing

One of the first signs that your computer has a virus is frequent crashing. If you're having trouble starting up, or if it seems your computer keeps trying to restart itself after each task is completed, this may indicate that there are files on your machine that are causing problems. If you find yourself unable to stop a virus from crashing and frequently restarting, consider checking for malware such as Trojans or rootkits when going online—these can often cause similar symptoms as viruses do by targeting specific parts of your operating system (OS). If this doesn't help and nothing else seems off about how things work on their own accord without any malicious intent behind them, then it's likely time for professional assistance!
