We live in an era where everything is connected to the internet and although this is a positive thing, it can also be a danger. Especially if we don’t know how to check if a computer or PC has viruses.

Unfortunately, there are many people who are dedicated to designing malware to steal private information and make money; That is why we must learn to take care of ourselves when browsing the internet and give top priority to the security of our data.

Check if my computer or PC has viruses

The first thing we should take into consideration is PC performance and application blocking. These two factors, on many occasions, are a clear sign that we have malware on our PC. Although we cannot deny that it does not always happen this way, there are many reasons why our PC can slow down, in this sense we always recommend optimizing Windows as much as possible.

Even if our computer works fine, it does not mean that we do not have malware. The viruses of a decade ago were often pranks and used system resources; most modern viruses work silently, covertly in the background, trying to evade detection in order to steal private information.

Basically, criminals develop malware to earn money, obviously this should not generate suspicion in the user in order to achieve their goal.

Even so, a low performance of our computer can be a warning sign. Many strange applications in our system can also indicate malware, although again, it is not safe.
