A
virus attack is one of the most feared threats for those of us who use a
computer, whether for work or leisure. Its effects can be
catastrophic: poor performance, application crashes or total
uselessness are just some of them. However, these consequences are
not always due to this viral cause, so in order to solve the problems that
arise, it is important to know if our device has been infected or not.
In
other cases, the opposite is true. It may be the situation that our
computer works perfectly, but, without knowing it, there is a virus doing its
thing. Viruses from a decade ago were often pranks that ran wild and used
a lot of system resources. Instead, modern malware now hides
silently and covertly in the background, in order to go unnoticed and
evade detection so that it captures all kinds of personal data.
Therefore,
although there are sometimes indications of the existence of viruses in our
device, this is not always the case. It is for this reason that it is
always positive to carry out some periodic operations in order to make
sure that we are not in a situation of risk. Here we explain some of the
most useful ways to know if a computer has been attacked by a virus.
Watch out! Signs of viruses
Before
delving into the possibilities of our equipment, let's start at the
beginning: how do we detect that we have a virus? There are many
signs that can make us think that our computer has been successfully attacked
and here we leave you some of the clearest.
· Hint 1. If we perceive that some extensions appear in our browser that we do not remember having installed, the best we can do is distrust.
· Indication 2 . If we detect that our antivirus is permanently disabled, either because we receive a notification or because we observe that it behaves in a strange way, it is very possible that it is a symptom that the computer has been infected. There are many strains of malware that are capable of disabling it , preventing it from updating, and preventing it from running scans.
· Indication 3 . Although it is not the only possible cause, some types of 'malware' affect performance and slow down the execution of programs. This is because cybercriminals can harness the power of our computer and use it for their own purposes such as mining crypto currencies.
· Indication 4 . Social media accounts are places where viruses can operate. Irregular behavior in any of them, such as the publication of information, news or images without our consent is a very common sign of the existence of a computer virus . If your friends say they have received strange messages from you or seen you posting strange comments, it is possible that your account has been compromised or that your computer is infected.
· Hint 5. A slow internet connection or unusually high network activity can often be attributed to 'malware'. There are many varieties of 'malware' that can hijack our internet connection and use its bandwidth to perform unwanted activities. In more serious cases, we can even lose connectivity completely.
· Indication 6 . If we notice that our device is getting hotter than normal or that the fans are spinning at maximum revolutions , even when the system is idle, it may be due to a virus. When a computer performs a resource-intensive task, the fans kick into full blast to help keep it cool and prevent internal components from overheating.
· Clue 7 . A very common symptom of the existence of a virus is the automatic and involuntary redirection to certain websites . These are often malicious and are used to obtain your personal information or encourage you to download more 'malware'.
· Clue 8 . If a multitude of pop-up ads suddenly jump on a screen , a virus is probably doing its job. Many potentially unwanted programs come bundled with adware that uses every opportunity to display unwanted advertisements on all kinds of issues and products.
· Clue 9 . The blue screen is one of the most feared phenomena by all. If this happens, the cause may be the existence of a virus, although not the only one. In these cases, identifying the exact cause can be tricky.

Clue
10 . Some
types of 'malware' are designed to look like ANTIVIRUS 'SOFTWARE' , with the function of sending false
notifications about the existence of some fictitious security threats and
indicating the need to buy a product that is supposed to solve the problem.
