Potential Virus Threat
What is a virus? How does a virus infect your system and what are the ways to resolve virus-related issues?
A virus is a malicious computer program that infects your system. It spreads from one computer to another in some form of executable codes. The malicious software includes computer viruses and worms, Trojan horses, root-kits, spyware, dishonest adware, and many more. These are basically programs written by hackers. These virus programs are placed into a commonly used program. The virus usually infects the executable files and programs. A virus remains inactive until you execute an infected program or start your computer from a disk with infected system files. After becoming active it loads into your system’s memory and hard drives. Some of the viruses are programmed to damage the data files on your computer and erasing your entire hard drive. Other viruses make your system behave erratically and even crash frequently. Also note that the viruses do not infect computer hardware.
Below mentioned are issues you might come across during a virus infection:
- Unsafe links and fraudulent websites
- E-mail spamming
- Changes in desktop background
Unsafe links and fraudulent websites
In case if you click on unsafe links and harmful websites you might get infected with viruses on your system. This may even crash your computer. An advanced phishing protection feature helps you neglect fraudulent sites that may try to steal your identity to access important financial information. The software application also includes a link checking feature that checks the safety of links in popular e-mail and instant messaging applications and warns you in advance of any online danger.
You might receive many fake e-mail invitations that would make you unzip a file to find out who has invited them. The message generally carries a mass-mailing worm and looks around on infected systems and sends e-mails to addresses it finds. This causes e-mail spamming. The user sees a .zip file attachment and opens it due to which virus spreads. Hence, it is recommended to never click on attachments or web links from unsolicited e-mails. You must also regularly apply security patches and updates and use a security solution that contains antivirus and firewall technologies to protect against known and unknown threats.
Changes in desktop background
A user might see changes in the desktop background to the image of an installation window displaying adware message on the computer. The screensaver also changes to the “Blue Screen of Death”. You might also find missing the background and screensaver tabs in the control panel. In order to resolve this issue, try logging in the safe mode and then perform an antivirus scan from a trustable website that offers free virus scans.
