Sometimes even a good antivirus cannot detect all the threats that can invade your computer. So, read the post to learn more. Below, we have listed the signs that will help you identify if your PC is infected – and what to do about it.

1) An abrupt slowdown in computer speed: malware and viruses have a tendency to slow down the operating system. You might notice the decrease in speed when surfing the Internet, when transferring files from your computer and it will be slow even when starting up.

2) Frequent crashes: if you are infected with any kind of virus or malware then you might know the infamous BSOD (blue screen of death), the BSOD is the clear warning that your computer is not working properly and is infected by virus or malware (mostly from malware).

3) The applications take a long time to open: if opening an app you notice errors or the use of more time to work, you need to scan your PC for viruses and malware.

4) Pop-ups that appear out of nowhere: windows jump on the screen with false proposals for the installation of the program, casino announcements or even adult sites. Act calmly and do not exacerbate the invasion even more.

5) Firewalls and anti-virus disabled: while performing a routine cleaning on the computer, you can see that the antivirus is not in great shape (it is the typical feature of many threats that disable security systems).

6) False security programs: security programs may appear that you have never installed or warnings on the screen to alert you that your computer is infected, with a simple click it scans and cleans your system. Beware of too good offers, avoid accepting these proposals and clean every trace of those programs that exist on your computer.

7) Forwarding sites: do you do a search on Google and exit another browser? Or click to go to a news portal and end up on a site with the “suggestion” to update a plugin like Flash? Normally, traffic redirection means that the software that should not be there has been installed. It can exist in the form of a browser extension or a code entered in the “Properties” tab of the “Destination” tab. You have to clear the browser cache and uninstall the extensions to see if the problem is solved.

8) Huge internet traffic: depending on the type of virus or malware hosted on your PC, it is likely that you can use the bandwidth to download data and files to the machine or “kidnap” the connection and turn the computer into part of a botnet. So, if the Internet is very slow, even when doing only daily activities, it’s good to be suspicious. In these cases, it is possible to use programs that monitor the traffic and the routing link, such as NetWorx Portable or iTraffic Monitor. Thus, the detected foreign objects should be immediately removed.

9) E-mail and suspicious messages on social networks: you know when you receive a rather suspicious e-mail of “photo party” from friends or you see that your friend has written some messages – usually suspicious links to erotic videos – on Facebook? This can mean infection, and usually, the victim clicked on the link embedded in those messages sent by someone else. In addition to looking for the source of infection, you must also change the passwords for these services.

10) You will find link files: if connection files appear on the desktop, you must be suspicious because there is the possibility that the computer has already been infected. Such viruses will not be able to be detected by a normal antivirus.

After reading this, one must be cautious by downloading a series of virus security programs. Knowledge is our best weapon.
