Signs That Your Computer May Be Infected With A Virus:
1. Slow computer: Sometimes, this may appear normal especially if you are working on databases and other process-intensive work. But if this is not the case, and the computer is still often running slower than usual, taking a long time to power up or open apps, it could be a sign that there is a virus on your computer.
2. Missing or corrupted files: If you notice a program that you often use suddenly showing a pop-up window or error message relating to missing files, it could be a possible sign of corruption, and most probably caused by malware.
3. Frequent system crashes or blue screen of death
4. New applications or process: Unfamiliar applications or processes appearing on the background.
5. Unexpected pop-up windows: Ads or error messages appearing on the screen.
6. Overworked hard drive: Viruses often damage your hard drive, causing you to hear some strange sounds. It will most likely sound like the hard drive is working extra hard or its fan is making whirring noises.
7. Spam emails: Emails sent automatically from your account without your permission.
8. Browser redirects
9. Disk is full: Some viruses leave a copy of themselves and create duplicates of system files that fill up your disk space.
10. Inability to download antivirus program updates or a malfunctioning firewall
If you are experiencing any of these symptoms, it is worth checking if your computer has a virus.

How To Spot The Symptoms Of A Pc Virus
PC viruses are like real-world viruses: they attack your PC and prevent it from working properly. So the first sign of a PC virus may well be your computer doing unusual things. Are you suddenly seeing stacks of pop-up adverts? When you try to search the internet, do you get weird results? Are you locked out of your computer altogether with a message demanding money?
These are all what computer experts call ‘malware’, which is short for malicious software. Each one is a slightly different kind, so the one that blasts you with adverts is called adware, the weird search results are the result of what’s called browser hijacking and the locked computer is called ransomware.
In the case of ransomware, never, ever pay the ransom or even worse, give the criminals your card details or bank details: they probably won’t unlock your PC but they’ll definitely make off with your money.
Although many viruses are obvious, some of them aren’t. Some of them are only obvious to other people. For example, if you get messages from friends, family or colleagues asking why you’re sending them weird stuff, that’s often a sign that a virus on your computer is sending out infected emails to try and spread to everybody in your contacts book.
The good news is that all of these problems are easy to fix.
Unwanted Programs Or Toolbars
Viruses can try to install additional programs or toolbars without your consent to give criminals access to your system. If you notice that there are new programs on your computer have you don’t remember installing, or your browser toolbar has changed, it could indicate a virus.
Also, if you start seeing unfamiliar icons on your computer, that could be another sign of a virus. The icons might have a question mark on them, and they might look different from the standard icons on your computer.

How To Know If Your Computer Has A Virus
There are few things as depressing as discovering that your computer has a virus and that you havent backed up all your treasured files and photos. All it takes is one wrong click or bad download.
Most people are willing to try everything up to and including an exorcism to get their machine back online. But are there ways to tell that your computer has been infected before it eats all your files? There are, as it so happens, and heres what you can do about it.
What to look out for: If you start your computer and find yourself faced with a barrage of pop-up ads, its safe to assume that you have a problem. Or multiple problems all popping up at once.
Some websites will automatically generate pop-ups but you can block these via the settings on most browsers. However, if your computer is bombarding you with an endless supply of pop-ups when your browser isnt open, its time to jump into action.
This form of attack usually means that youve been infected by a type of Adware or Trojan tracker. One way Adware makes its creator money is by creating unwanted links to sites or throwing up windows to some pretty unsavoury domains. You accidentally click the link and the hacker makes advertising money.
The best solution is to use a good malware removal tool to attack the malware and regain control of your computer. One advantage of the rise of Adware is the improvement in anti-Adware software to combat the threat. This will scan your system and delete any viruses.
My Computer/laptop/smartphone Is Very Slow

Your Computer Is Sending Messages From You
If your email accounts, social media accounts, or other online services start to have problemsand you notice unusual emails or messages being sent from your accountsthis may be a sign that your computer has been infected with malware, Walsh says. Those accounts may have been penetrated directly, but it is possible that your passwords have been lifted using a keylogger on your machine.
Maintain Your Installed Programs
One of the main ways viruses gain access to a system is through security lapses in existing software. Therefore, as the first step to prevent your computer from getting infected in the first place, you should make sure your applications, antivirus software and operating system are up to date. This is doubly important when it comes to your operating system, since Apple, Microsoft and other providers regularly release security patches to deal with potential weaknesses. You can also reduce the number of potential vulnerabilities for cybercriminals to exploit by uninstalling applications you don’t use.

Scenario #: I Keep Getting Annoying Ads That Are Opening Randomly Or Strange Messages On My Computers Screen
Unexpected pop-ups which appear on your screen are a typical sign of a malware infection that wreaks havoc on your computer.
This form of malware is known as spyware and is designed to collect and steal users sensitive data without their knowledge.
In this particular case, the main issue is not only the numerous pop-up windows that affect your Internet browsing. Its also quite difficult to remove them from your system.
These pop-ups are not only frustrating, but they usually come bundled with other concealed malware threats and can be far more destructive for your OS.
They could be disguised as legitimate programs and actually track your web browsing data or monitor your online activity to collect passwords and other personal information.
We strongly recommend you NEVER CLICK on a suspicious pop-up!
To keep your computer away from malicious threats, make sure you apply these security measures:
Removing Virus Or Malware By Recovering The Computer
If a virus is found, the virus might have already damaged or destroyed some files on the computer. The antivirus software might not be able to repair the damage. If the software cannot repair the damage, the computer might need to be fully recovered.
For more information, see HP PCs – Reset the computer.

Your System Tools Have Been Disabled
Another common defense mechanism for many viruses is to lock a user out of their control panel. This prevents many users from being able to check the system settings that would show them whats wrong with their computer. If you go to check your control panel and receive a message saying that only administrators are allowed access, thats another possible sign that you have a malware infection.
So You’ve Got Malware Now What
If you think that malware has taken up residence in your PC, install a powerful antivirus application or security suite immediately. Already got one? Then apparently the malware got past its protection. Make sure your antivirus is fully up to date, and run a full scan.
If you still have an unwanted app your regular security software can’t get rid of you can scan your PC again with an on-demand cleanup tool, such as Malwarebytes. Do whatever it takes to get that nasty, malicious program out of your system as soon as possible, before it invites friends to make your security problems even worse.
Once you’ve dealt with the immediate problem, check your defenses. Make sure that you’ve installed an antivirus or security suite that gets high marks from PCMag, and that everything is up to date. That should take care of protecting your local data. For another layer of protection, install a virtual private network, or VPN. By running your internet connections through an encrypted channel, the VPN protects your data even when it’s in transit.

The Latest Trend: Ransomware Attacks
Ransomware is a particularly nasty practice wherein cybercriminals use a type of malicious software that blocks access to a computer system or data, usually by encrypting it, until the victim pays a significant fee to the attacker, says Zohar Pinhasi, CEO of MonsterCloud. Instances of the attacks are surging according to Symantecs 2019 Internet Security Threat Report, attacks on enterprises are up 12 percent. A new business will fall victim to an attack every 14 seconds this year, according to Cybersecurity Ventures, and the attacks have generated millions of dollars for criminals. Attacks are on the rise for individuals, too. If you find yourself the victim of a ransomware attack, seek professional help by a cybersecurity company or expert immediately, he suggests. You should also report it to the local authorities and the FTC.

Your Computer Fan Starts Running Randomly
The fans inside your computer are critical for expelling warm air and drawing cooler air into the case. When your computer performs a resource-intensive task such as playing a game, encoding a video or rendering 3D files, your fans kick into overdrive to help keep your computer cool and prevent the internal components from overheating.
Strange fan behavior can be the sign of a computer virus. If youve noticed that your PC or laptop is getting unusually hot or the fans are spinning at maximum revs even when your system is idling, there may be an issue with your computer.
