When using your personal computer, you are probably aware of the temperamental nature of your machine. The computer will be functioning perfectly this minute, and then it can suddenly slow down, become unresponsive, or even reboot itself. There is a certain manner that you expect the computer to function and any deviation from the norm may be an indicator that something is not right. For instance, you expect that the machine will only reboot when the user issues a command requiring the system to reboot. When such commands happen abruptly without you issuing the command or any warning, then something may not be right with the operating system. The following pointers will help you know if your computer has virus:
Are there messages that you did not send?
For most computers system viruses, the aim is to spread to as many parts of your computer as it is possible. One way of spreading is to send messages to other computer users in the hope that their computers will also acquire the same virus.
The virus can use various platforms of your internet connection to send the messages to other users. First, they can send spam messages through your regular email accounts to the other people that you contact. Alternatively, the virus can take charge of your social media accounts and send out messages to friends that you connect with on social media. Monitor the items you send using your email or social media accounts, especially when you receive unexpected responses or messages from others. If there are messages that you did not send, then your computer may be infected by a virus. In fact, some of these messages have links directing the recipients to the source of the virus.
Scam messages are a popular type of virus referred to as "ransom ware". When using your computer, you receive a message stating that you are blocked from accessing certain programmes or files, which is not the case in the real sense. The virus blocks some fundamental programmes from functioning and running claiming that the message is a requirement of the law enforcement. It is often used by people who want to make you pay "ransom" in order to restore your computer, which is a scam.
Pop-up advertisements occur on browsers when you are using the internet and they make your browsing experience quite annoying. They redirect you to pages that are irrelevant because you do not intend to visit them at that time. These pop-ups are an indication that your computer has been infected.
No symptoms at all
Some viruses can hide deep within your system and you cannot detect them unless you are tech-savvy or you know your way around the operating system. They can corrupt and slow down your computer by attaching themselves to places such as the registry. Such viruses are dangerous as they can collect personal information from your system including passwords. The hackers can use the information to commit a crime in organisations such as banks. You should consult a computer repair expert on the best anti-virus program you can get to use to scan your computer and remove them.Share
