Malicious code can be encoded in various formats (e.g., UUENCODE, Unicode), contained within compressed or hidden files, or hidden in files using techniques such as steganography. Malicious code can be inserted into systems in a variety of ways including web accesses, electronic mail, electronic mail attachments, and portable storage devices. Malicious code insertions occur through the exploitation of system<br \/>\nvulnerabilities.<\/p>\n<p>Further Discussion<br \/>\nUse anti-malware software to scan for and identify viruses in your computer systems and determine how often scans are conducted. Real-time scans look at the system whenever new files are downloaded, opened, and saved.
