KNOW IF YOUR PC IS INFECTED BY VIRUS

-

We present you 10 ways to know if your computer is infected with viruses based on 10 symptoms to identify the failures. Viruses can alter the proper functioning of computers and these alterations can be identified. Learn how to know if your pc is infected.

PC infected by virus
The companies, focused on computer security or antivirus, presented a set of symptoms so that they can indicate how your computer is being a victim of malicious code such as viruses.

Here are the 10 characteristics to consider:

1. The fan starts at full speed when the computer is idle: This may indicate that a program is running without the user's knowledge and that a considerable amount of resources are being used. Of course, this could also be a product of Microsoft's installation of updates, for example. Another problem that can cause the fan to work is excessive dirt on the computer or a failing CPU fan.

2. Your computer takes a long time to shut down, or does not shut down properly: Malware often has errors that can cause a variety of symptoms, including a long shutdown or failure. Unfortunately, operating system errors or conflicts with legitimate programs can also cause the same symptom.

3. Observe content on your Facebook wall that you have not submitted: There are some other reasons other than malware or unauthorized access to the account for this problem to appear. If you see what happens, you should definitely change your password and make sure that the system is not infected. Ideally, make sure your computer is free of malware before changing your password and not using your Facebook password on multiple different sites.

4. Applications are very slow: This can happen because hidden programs are using a large amount of computer resources. But it could also be caused by other problems.

5. Unable to download operating system updates: This is a symptom that cannot be ignored. Even if it's not being caused by a bot or other malware, if you don't keep your antivirus software up-to-date, your system will get infected.

6. Unable to download antivirus updates or visit vendor websites: Malware often tries to prevent antivirus or security solutions from being installed or running. The inability to update the antivirus or visit the manufacturer's website is a very strong indicator of the presence of malicious code.

7. Internet access is very slow: If a bot is running on the system to, for example, send large amounts of spam, carry out an attack against other computers or upload / download large amounts of data, it can cause access the Internet is very slow.

8. Your friends and family have received emails that you did not send: This could be a sign of a bot or other malware, or that your webmail account has been compromised by an attacker.

9. Pop-up windows and advertisements open, even when you're not using a web browser: While this is a classic sign of adware, bots can install this malicious program on your computer. You should definitely address this issue.

10. Windows Task Manager displays programs with strange names or descriptions: Using Task Manager requires some skill and research. Sometimes legitimate software can use strange names. An entry in the Task Manager is not sufficient to identify a program as harmful. While it can help find malicious software, additional steps must be taken to validate the results. Deleting processes, files or registry entries just because it is suspected to be a bot or other malware may result in the computer not even starting up. Be very careful when making assumptions and taking action on them.
