Malware: symptoms of infection
PandaLabs presents the top ten most frequently encountered signs that should alert the user about a possible infection of his system.
The research laboratories of the publisher Panda formulate a series of ten symptoms that can often diagnose an infection in his system. Where appropriate, a line analysis can be useful to confirm the diagnosis, especially since it can be done over a security solution installed that would not have winced. Numerous vendors offer such a scan line.
The ten symptoms of infection by PandaLabs:
1 - My computer suddenly became very talkative: Many popups appear on the desktop messages and advertisements claiming that your PC is infected and in need of protection ... These are typical signs of infection. No doubt about it: a spyware or fake anti-virus has infiltrated your PC.
2 - My computer is extremely slow ... This can mean many things, including a virus infection. When malware (viruses, worms, Trojan horses ...) infects your PC, it performs tasks that can consume many resources, which makes your computer slower than usual.
3 - Programs do not start. It has been several times that you try to launch an application from the Start menu or the desktop and nothing happens? Sometimes it even another program that opens instead? As in the previous case, if another problem may be the cause of this dysfunction, the presence of a virus on your computer is an assumption to take into account.
4 - I can not connect to my Internet connection is very slow. The loss of Internet connection or a slower connection may be a sign of infection, but also a problem with your ISP or your modem. If malware is present on your PC and connects to malicious sites, this reduces the available bandwidth and may even make it virtually impossible to access the Internet.
5 - When I connect to the Internet, all sorts of windows open and the browser displays the pages that I had not requested. This behavior is a sure sign of infection. Many malware are designed to generate traffic to websites and bring you donated to your knowledge on the pages and malicious fake sites to get you to reveal personal information like your bank details and passwords.
6 - Files have disappeared! Although less frequent than in the past, some threats are designed to delete, move or encrypt documents ... and then ask you to pay to get them.
7 - My antivirus has disappeared and my firewall is disabled! Once the infected PC, the first action of the virus is often an attempt to disable security systems. If one software is disabled, this may be due to a problem specific to this one but if all your security systems are deactivated at the same time, only one conclusion: your PC is infected.
8 - My computer tells me in a strange language ... The language of some exchange programs, the screen is rotated, the office is attacked ... No doubt, a virus has intruded on your PC!
9 -The libraries of games and software have disappeared from my computer. Again, this may be a sign of an infection or a problem any other, for example an uninstall incomplete or poorly done.
10 - My computer has become completely mad. If your PC starts to act alone, if you find that emails were sent from your PC without your knowledge that Internet sessions or programs open and close by themselves, it is likely that you are infected with malware.
