For the common home user, it requires some knowledge and great effort to find out if one's PC is attacked by, for example, viruses. The usual recommendation is to install an antivirus solution, but when browsing the web, the user is exposed to so many threats that this is not enough. To overcome this problem, Panda Labs has prepared a guide with 10 signs that the user's PC has viruses or other malware. 1. If the screen is filled with strange popups, advertisements in new windows, windows that tells that the PC is infected with viruses, etc., it is typically spyware or a false antivirus program. 2. Running the PC suddenly, very slowly this is typically a sign of a virus, worm or trojan or other malware. 3. If a program does not start, it is usually a sign of infication. 4. The connection to the Internet has gone or is running very slowly. If this is the case, it is usually because malware on the PC uses the connection to link to other computers in a botnet or send mail with viruses to the user's address book. 5. Immediately, webpages appear that the user has not written in the browser's address bar.! This is another sign that the PC has been attacked, and the user should pay close attention to the fact that no malware pages are sent. It is about raising the connection to the broadband! 6. Are the pictures from the wedding gone missing or the letter to the bank about the conversion of the loan? Let's not hope it happens, but if the user experiences it, the PC must be thoroughly investigated for viruses and other malware. 7. The antivirus solution has disappeared and the firewall turned off - another very sure clue that the PC has software that disables all security mechanisms. 8. If the screen is "eaten" by small insects or is filled with Chinese or Russian characters, this is very sure that the computer is crazy with malware. 9. If one or more files required for running a game or program to run has disappeared, there may also be viruses on the PC, but possibly. Also, the installation has not drove completely after the book. 10. The computer has got its own life! If the PC has sent emails that the user has not written, programs that the user has not installed is very likely to be a virus on the machine. If any of this is experienced in daily use, PandaLabs recommends scanning with an antivirus scanner such as Panda's Active Scan. The Panda Active Scan can be tested at http://www.pandasecurity.com/.
