Just detecting changes is not enough, however; the detection must have some &#8220;intelligence&#8221; behind it to avoid confusion.<\/strong><\/p>\n<\/div>Integrity checking products work by reading your entire disk and recording integrity data that acts as a signature for the files and system sectors. An integrity check program with built-in intelligence is the only solution that can handle <strong>all<\/strong> the threats to your data as well as viruses. Integrity checkers also provide the only reliable way to discover what damage a virus has done.<\/p>\n<p>So, why isn&#8217;t everyone using an integrity checker? In fact, many anti-virus products now incorporate integrity checking techniques. One problem with many products is that they don&#8217;t use these techniques in a comprehensive way. There are still too many things not being checked.<\/p>\n<p>Some older integrity checkers were simply too slow or hard to use to be truly effective. A disadvantage of a bare-bones integrity checker is that it can&#8217;t differentiate file corruption caused by a bug from corruption caused by a virus. Advanced integrity checkers that incorporate the capability to analyze the nature of the changes and recognize changes caused by a virus have become available. Some integrity checkers now use other anti-virus techniques along with integrity checking to improve their intelligence and ease of use.<\/p>\n<p>If you choose an integrity checker, be sure it has all these features:<\/p>\n<ul>\n<li>It&#8217;s easy to use with clear, unambiguous reports and built-in help.<\/li>\n<li>It hides complexity, so that complicated details of system file or system sector changes are only presented if they contain information the user must act upon.<\/li>\n<li>The product recognizes the various files on the PC so it can alert the user with special warnings if vital files have changed.<\/li>\n<li>It&#8217;s fast. An integrity checker is of no use if it&#8217;s too slow.<\/li>\n<li>It recognizes known viruses, so the user doesn&#8217;t have to do all the work to determine if a change is due to a software conflict, or if it&#8217;s due to a virus. This also helps protect the integrity checker against attacks by viruses directed at it.<\/li>\n<li>It&#8217;s important that the integrity computation be more sophisticated than a mere checksum. Two sectors may get reversed in a file or other damage may occur that otherwise rearranges data in a file. A simple checksum will not detect these changes. A cryptographic computation technique is best.<\/li>\n<li>It&#8217;s comprehensive. Some integrity checkers, in order to improve their speed, don&#8217;t read each file in its entirety. They read only portions of larger files. They just spot check. This is unacceptable; it&#8217;s important to know the file hasn&#8217;t changed, not just that some of the file hasn&#8217;t changed.<\/li>\n<li>It checks and restores both boot and partition sectors. Some programs check only files.<\/li>\n<li>For protection, it should have safety features built in (e.g., ability to define the signature information file name and store the information on a external media).<\/li>\n<\/ul>\n<p>While using an integrity checker is an excellent way to monitor changes to your system, with today&#8217;s operating systems so many files change on a regular basis it&#8217;s imperative that you also use a good up-to-date scanner along with the integrity checker or for the integrity checker to have that capability built in.<\/p>\n<h4>Summary<\/h4>\n<ul>\n<li>Integrity checking products read the disk and create signature information to determine changes.<\/li>\n<li>Coupled with virus identification, using integrity checking should be able to detect most any virus with the bonus of also detecting data corruption.<\/li>\n<\/ul>\n<table style=\"margin: 0pt; width: 100%;\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\" align=\"center\">\n<tbody>\n<tr align=\"center\">\n<td style=\"padding: 0 0 0 0;\" colspan=\"2\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.cknow.com\/cms\/wp-content\/uploads\/2013\/02\/arrow_up.png\" alt=\"Up Arrow\" width=\"16\" height=\"16\" class=\"alignnone size-full wp-image-579\" \/> <a href=\"https:\/\/www.cknow.com\/cms\/vtutor\/virus-protection.html\">Virus Protection<\/a> <img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.cknow.com\/cms\/wp-content\/uploads\/2013\/02\/arrow_up.png\" alt=\"Up Arrow\" width=\"16\" height=\"16\" class=\"alignnone size-full wp-image-579\" \/><\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 0 0 0 0;\" align=\"right\"><a href=\"https:\/\/www.cknow.com\/cms\/vtutor\/scanning.html\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.cknow.com\/cms\/wp-content\/uploads\/2013\/02\/arrow_prior.gif\" alt=\"Prior Page\" width=\"48\" height=\"32\" class=\"alignnone size-full wp-image-578\" \/><\/a><\/td>\n<td style=\"padding: 0 0 0 0;\" align=\"left\"><a href=\"https:\/\/www.cknow.com\/cms\/vtutor\/interception.html\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.cknow.com\/cms\/wp-content\/uploads\/2013\/02\/arrow_next.gif\" alt=\"Next Page\" width=\"48\" height=\"32\" class=\"alignnone size-full wp-image-577\" \/><\/a><\/td>\n<\/tr>\n<tr>\n<td style=\"padding-right: 20px; text-align: right; width: 50%;\"><a href=\"https:\/\/www.cknow.com\/cms\/vtutor\/scanning.html\">Scanning<\/a> <\/td>\n<td style=\"padding-left: 20px; width: 50%; text-align: left;\"> <a href=\"https:\/\/www.cknow.com\/cms\/vtutor\/interception.html\">Interception<\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Comments from original:<\/p>\n<p>pauline<br \/>\nSaid this on 2011-08-25 At 12:24 pm<br \/>\neverytime i play kuma games it always freezes. please fix it.<\/p>\n<p>[Please ask them.
