Malware: The Worst Malware Viruses that Infect Desktop Computers
Blogger Ann Johnston
When your computer is infected with malware it can damage and disable your operating systems and programs. Certain types of malware are easier to detect and isolate. But, there are a few different types of malware that are sophisticated and virtually impossible to detect or destroy.
Therefore, it is important to understand the 4 types of malware that can do the most harm to your computer and network. If one of these 4 types of malware infects your computer, it can be difficult to detect with standard antivirus programs. That is why many people are forced to backup their data and wipe their hard drives in order to destroy the malware.
The Rootkit malware is created to gain control of your administrator-level access. This allows the hacker or operator of the program to completely take over control of your computer or network. The second goal of the program is to conceal its existence, so it can’t be detected by anti-malware programs.
The Rootkit malware has the ability to completely hide its existence which makes it very difficult to detect. Therefore, once a rootkit virus has infected your computer, it can be practically impossible to detect the virus and remove it from your system. Unfortunately, many computers infected with this virus had to have their hard drive securely erased and reloaded from a trusted backup or system disks.
The Ransomware virus will hold your computer for ransom and try to extort money. Some hackers encrypt your data with a key and demand large sums of money to be wire transferred to their account to unlock your computer. However, if you fail to send the money, the intruder will threaten to keep your key and never release it. Therefore, your data is locked and useless to you.
In 2013 the most famous Ransomware program was set loose on the Internet. CryptoLocker extorted over 3 million dollars from its victims in the first two months.
However, thanks to the Whitehats they found a key to unlock CryptolLocker Ransomware and restore data.
Certain malware programs leave traces behind that are difficult to remove. The Persistent Malware infects your computer with multiple malware programs. If an antivirus or malware removal tool detects the infection, it removes or quarantines only part of the malware. However, the malware can’t be completely removed from your computer.
Once the infection is removed from your computer the traces of the program can still direct your web browser back to the malware site. Afterwards, the malware re-infects your computer. This type of malware uses a vicious cycle once it is detected to re-infect your computer.
The firmware-based malware is the most difficult malware to detect and remove from your computer. The malware is installed in the hardware components of your bios, hard drive or other peripherals. Furthermore, this form of malware can’t be detected by any anti-virus or malware programs because they aren’t designed to scan your computer’s hardware or firmware. In some cases the only way to successfully remove this virus is to replace the hardware it has infected.
Malware Removal Tools
Once you suspect your computer has malware installed, it is recommended to download these programs. Scan your computer and remove or quarantine the malware.
