How Do I Know If My Computer Is Infected With Malicious Software
There are some common signs that may indicate your computer has become infected with malicious software– whether its adware, spyware, trojans, viruses, or some other form of exploit. While malware covers a broad category of software designed to damage and operate against the users intent, the symptoms can be easily recognizable for casual users.
Scan Your Computer For Viruses
Once we know that Windows Security Protection is running properly and up to date with the newest virus definitions, its time to scan your computer and see if the program can find any viruses.
From the Windows Security screen, click on the Virus & threat protection icon. This will bring up the details around your Anti-Virus program.
Itll have information on whether it has detected any threats already, when it last ran a scan on your computer, and if there are any immediate actions you need to perform.
You should check for any current threats that might have been detected on this screen. You should also scroll down the page until you see the section regarding the virus definition updates and make sure the last update isnt older than 1 week old.
Its highly recommended that you run a virus scan on your computer at least once per week. Update your virus definitions and scan your computer once per week. I would recommend that you create a routine for yourself so that on a specific day of each week you check the status of our Anti-virus program and download the latest virus definitions and run a full computer scan.
Now that we know your Anti-Virus software is up to date on virus definitions and it looks to be running properly on your computer, lets start a full computer scan.
Once the Scan Options screen comes up, then choose the Full scan option.
Once youve selected full scan, scroll down to the end of the page and click on Scan now.
How Can Iphones Get Malware From Websites
Though its rare, it has been found that iOS devices at times can be infected by malware or viruses, even if the devices arent Jail-broken. Now, how can iPhones get malware from websites or other sources?
It needs to be remembered that, no matter how strong a platform may be, there will be still some exploitable weaknesses. The malware, which are malicious software, may come from infected websites, emails, and third-party programs. Although malware is typically tends to be more associated with PCs and Windows devices, it has been detected that it can also affect Macs, iPads, iPhones and other Apple devices. Even if you dont jailbreak your iOS device, despite very rigid control from Apple, App Store cannot always keep malicious apps from finding ways into your device. Hackers can find alternative methods to compromise it. One way hackers distribute malware is by tricking iPhone users to download free versions of apps that users would otherwise have to pay for.
Security researchers at Google have also recently found evidence of efforts to hack iPhones using websites which would discreetly implant malware or malicious software to gather contacts, images and other data. Nevertheless, these exploits tend to live only for a very short period as Apple issues regular updates of its devices to the latest software to make sure they are adequately protected.

A computer virus is a type of malware designed to make self-replicate, i.e. to make copies of itself on any drive connected to your computer.
Computer viruses are so-called because, like real viruses, they can self-replicate. Once your computer is infected with a virus, this is how it spreads. When a computer virus infects your computer, it may slow it down and stops it working properly.
There are three main ways that your computer may have become infected with a computer virus.
The first way your computer could become infected from removable media, like a USB stick. If you insert a USB stick or disk into your computer from an unknown source, it may contain a virus.
Sometimes hackers leave infected USB sticks or disks in peoples workplaces, or public places like cafes to spread computer viruses. People sharing USBs may also transfer files from an infected computer to one that isnt infected.
Another way your computer become infected with a virus is through a download from the internet.
If you are downloading software or apps to your computer, ensure you do so from a trusted source. For example, the Google Play Store or Apples App Store. Avoid downloading anything via a pop-up or a website you do not know.
The third way your computer could become infected with a virus is if you open an attachment, or click on a link, in a spam email.

How Do Computer Viruses Spread
Computer viruses spread by self-replication. Once inside your computer, they make copies of themselves and spread via infected email attachments, poisoned macros, or malicious links. A virus might email itself out to all your contacts, who then unwittingly send it on to all their contacts, and then their contacts contacts, causing exponential spread.
Email is one of the most popular malware delivery methods, which is why email security is critical. Viruses and other malware can also spread through file sharing and software bundles. When you download an app from an unreputable source outside Apples App Store or Google Play, it can come packaged with malicious software or bloatware.
Malware also spreads through vulnerabilities in outdated software. Many software updates are released to plug security holes. If you dont update your software regularly, dangerous hackers can exploit the vulnerabilities in old software to gain access to a system and spread malware.
Check To See If Windows Security Protection Running Properly
The most popular computer operating system today is Microsoft Windows, which the latest version is Windows 10. The nice thing about Windows 10 is that it comes with a free version of an Anti-Virus program. Lets take a look at how to ensure the program is enabled and working properly.
If you go to your Windows 10 desktop, lets find the Windows Security Icon so we can look at the status of the program.
Find the up arrow icon that usually on the lower right corner of your Windows 10 desktop screen. See image below:
Once you left click on the up arrow icon, youll see a list of programs that are running on your computer. Find the icon that looks like a shield. See image below:
When you left click on this icon, youll have a new window pop-up on your screen that will give you an good overview of the current status of your Windows Security.
What were looking for is that the status of all the security protections have a green check mark like the screen below.
All green check marks means that the Windows Security program is running properly and your Anti-Virus protection is fully operational. Because new computer viruses are created everyday, its very important that the Anti-Virus program does an update of new virus definitions either daily or weekly. The green check mark over the Virus & threat protection shield does indicate that the Anti-Virus program is up to date and good to go.
