What is virus protection and encryption?
antivirus software, such as Norton 360
How do you protect computer and data?
Backups Encryption Virus scanning Password protection
What virus runs a program that searches for common data files compresses them and makes them unusable?
That would be an encryption. Encryptions are usually found within safe looking files and programmed macros.
What are ways for malware authors to get around antivirus engines?
Some methods they use are: Stealth mode - the virus intercepts requests from the anti-virus program and returns the information the anti-virus program would expect from a non-infected program. Self-modification or mutation - the program changes its code slightly with each infection to make it harder for anti-virus software to create a "signature" for the virus Encryption of the payload - this may obfuscate the actual virus, especially if a different encryption key is used each time. The code still has to have a decrypting function attached to allow the virus to unpack and execute. Polymorphic viruses - this is sort of a combination of the encryption and mutation tactics. The virus payload is encrypted and the decrypting function modifies itsself with each infection to make it very tough to create a signature for the virus.
What features does McAfee Virus Protection offer for home users?
Features that McAfree Virus Protection offers home users include virus protection, email security, encryption, and Internet security. It also does frequent scans on your computer to check for malware.
How can virus bypass antivirus?
First hacker make the virus and scan it for virus... He then looks at the virus definition Anti-Virus gives to his virus Then Hacker tries to remove that anomaly by changing the code... He then crypts his virus with a encryption program specially designed to encrypt the viruses known as Crypters. Crypters encrypts the virus code in byte format using encryption algorithms. That way anti-virus won't have a chance to detect it. But as Anti-Viruses are becoming more strong, the viruses also... At the time of execution of crypted virus's code has to be decrypted... so that's where AV's hooks catches the virus. To remove this problem virus uses something called Portable Execution. This technique loads the virus code to memory, or into some other program like 'explorer.exe' and executes it. This way virus without even touching the Hard Disk of victim can do it's job and hence bypass the AV, just like a ghost.
What is Scrambling of messages at the sending end and unscrambling them at the receiveing end is called?
Encryption
What is an encryption virus?
An encryption virus is a type of malicious software that encrypts a victim's files or computer system, rendering them inaccessible until a ransom is paid. This type of virus is also known as ransomware and is often used by cybercriminals to extort money from individuals or organizations.
What is the difference between advanced encryption algorithm and encryption algorithm?
People have developed many encryption algorithms. One particular encryption algorithm is the Rijndael algorithm, usually called the AES or Advanced Encryption Standard.
Is encryption crackable?
Encryption is converting plain text into cipher text . Yes, encryption can be cracked and then the text can be decrypted.
Is pgp encryption safer than other encryptions?
"Evaluating cryptography is difficult since without 'breaking' the encryption its hard to say whether one encryption is better or not. Pretty Good Encryption (PGP) is asymmetric, that is the encryption and decryption keys are different which may give it an edge on symmetric encryption."
What are the price ranges of encryption software?
Basic encryption (up to 256 bit encryption) software costs around $400 per year. Encryption softwares are not 100% foolproof.
