Best Computer Scan Software To Scan Computers

Best Computer Scan

Aside from the business sector, home users remain vulnerable to viruses and other threats. Possessing the best computer scan software will help in protecting and making sure that there are no hidden threats inside their systems that could cause big trouble in the future.

According to the Microsoft Security Intelligence Report and Consumer Reports, the estimated cost of all home users impacted by viruses, spyware, and phishing is around $4.55 billion. 40% of households in the US are directly affected by computer viruses. This only shows that it is really necessary to have the best computer scan software if you want to scan computers and protect it from viruses and other forms of threats.

Virus Definition

Computer viruses are a small piece of software program or scripts that can greatly affect the health and output of the computer. These malicious software programs are capable of creating files, moving files, erasing files, consume a large amount of computer's RAM memory, and it can cause your computer not to function properly if it is not scanned using the best computer scan software.

There are some viruses that can replicate themselves, attach itself to other programs, and travel across the entire local networks. The most common way of spreading viruses these days is through the sending of email attachments. To better understand viruses, it would be better to identify different types of viruses.

Types Of Common Virus

Fat Virus

If you scan computers and use the best computer scan software, you might encounter this type of virus. This breed of virus usually destroys the file allocation system where the information about files is stored, including the location of the file.

Spacefiller Virus

If you scan computers and use the best computer scan software, you might detect this type of virus. This breed of virus attaches itself to the file and can alter the start of the program or change the encrypted code. Sometimes, it is hard to be detected because it implements a stealth technique so that the victim will not determine the increase in the file code.

Sparse Infector

If you scan computers and use the best computer scan software, you might detect this type of virus. This strain of virus uses a different technique to minimize its detection. The infection process of this virus is occasional, making it difficult to be detected by the antivirus.

Stealth Virus

If you scan computers and use the best computer scan software, you will encounter this type of virus. A stealth virus tricks the security software by portraying that they are real files of the program and it could also intercept the request to the operating system. Some traditional antivirus finds it difficult to detect this threat. It may also temporarily remove itself from the system without deleting itself.

Nonresident Virus

If you scan computers and use the best computer scan software, you might also encounter this type of virus. The nonresident virus replicates through modules. When the module is executed, it will select one and then infect other files.

Network Virus

If you scan computers and use the best computer scan software, you might encounter this type of virus. This breed of virus spreads out its infection through Local Network Area (LAN) and through the internet. This kind of viruses replicates through shared resources, including the shared drives and folders. Once it entered the system, it will then look for another system to become its victim.

Companion Virus

If you scan computers and use the best computer scan software, you might encounter this type of virus. This kind of virus doesn't survive without accompanying an existing file or folder. For it to carry out damages, the file or the folder must be accompanied by a companion virus that is currently running.

Encrypted Virus

If you scan computers and use the best computer scan software, you might detect this type of virus. This type of virus uses a malicious code that is encrypted and this will make it difficult for the traditional antivirus to detect the virus easily. They can only be detected when they decrypt themselves during the replication process. However, this type of virus doesn't delete any files or folders, but they can greatly affect the system's performance.

File Infector Virus

If you scan computers and use the best computer scan software, you might encounter this type of virus. This virus can also infect executable files or programs. When you run these programs, the file infector virus is activated as well which will make your whole system runs very slow and may damage some programs.
