Our operating systems are unsafe. They are defended to a certain extent, but still insecure. The cause of this lies in the fact that they were designed and made at the time when the problem of protection just did not grow. And even so-called update services were not aimed to enable millions of users to oppose themselves against a menace. It just occurred that most of the determined errors pertain security. testing to reject this defect users have to use third-party software - anti-viruses, firewalls, spam filters and anti-spy ware. Installation of such software can produce a false belief of security.

The user must not forget that this means of security is not a magic wand but software, just like the windows. It also can include errors and be dangerous. some reports pertaining exposed blots in famous anti-virus programs. The author of these reports shows vital exposures, by using which a poisonous program can not only block the work of anti-virus software but also accomplish malicious code at the user computer. Designing Arovax conceal we have looked a technical problem which, if solved in a wrong way, could cause vulnerabilities in our product. We have found our own solution but throughout the discussions a number of dissimilar versions were aimed, so we determined to check the least desirable variants with other software products covering with real-time protection.

Our investigate has shown that many producers either don't pay attending to this problem at all or use an thoroughly unsafe variant.

For instance, various manufacturers of very popularity anti-spy ware programs use the following mechanism to deliver their programs from memory earlier updating them
