What should you know about spyware?
Spyware presently is one of the most dangerous sources of threats for home and corporate networks. Such approved means of maintaining security as antiviruses and firewalls in most cases assist to withstand external threats, but appear to be feeble against spyware.
Spyware represents a software, designed for tracking user’s actions and is frequently installed without user’s knowledge. Among the harmful programs, which refer to spyware, we can mark out keyloggers — the programs which write down into a special file everything typed on keyboard. It also traces what web-pages are visited by user. Sometimes it even comes up to stealing passwords and other important information. Some kinds of spyware open a gap — a back door in system’s security and allow violators without being detected to control it. Others can not only log the input information but also screen pictures, video from a web camera or audio from microphone.
Spyware penetrates computer by different ways — using common vulnerabilities of operating system or browser and disguises itself as a legal software — e.g. Windows update. Some cases are known when spyware applications were included into software install packs, in other cases spyware was preinstalled on computers, which were for sale. Hence spyware programs use all the possible ways of getting on a computer: through legal software as well as through harmful programs like worms.
In most cases spyware installation happens by approbation of an ignorant user. Here are some recommendations, which can prevent unpremeditated spyware installations on your PC:
- Be cautious, when during Internet surfing an installation window of a new program appears — it is very probable someone wants to infect you with spyware.
- Stay alert with pop-up advertisments — clicking on them can lead to spyware installation.
- While installing programs and media contacts pay attention to the license agreement, which many users don’t care to read attentively — some software vendors with spyware try to evade by clearly writing that their programs contain spyware.
- Use protective programs only from reliable producers: some kinds of spyware programs disguise themselves as their opponents in order to get to your computer. There even exists a list with such programs and you can find it on http://www.spywarewarrior.com/rogue_anti-spyware.htm
Not all kinds of spyware try to obtain access to your system through the front door. It is very difficult to detect presence of the most dangerous spies as well as to remove them manually even for an experienced user. It is impossible to remove such stealthy programs through «Add/Remove Programs» panel.
Spyware presence can damnify business as well as personal reputation, can lead to information drain, make some resources and opportunities inaccessible. In addition one should bare in mind that during its work spyware uses critical computer resources — its calculating power and random-access memory, which are driven away from tasks appointed by user. In many cases spyware activity significantly slackens computer performance.
Be sure that the operating system is safely protected — install all the necessary updates, especially those fixing the errors, which lead to vulnerabilities. Many spyware programs are created to interact with Internet Explorer, so that’s why your Internet surfing will be more secure if you choose browsers like Mozilla Firefox or Opera.
Install protective anti-spyware support beforehand — it is simpler and cheaper than to spend later hours or even days of your time for salvation of problems with your PC. You will need a reliable program with constantly updatable list of computer fraudsters. Among such free programs we can mark out several applications like Ad-Aware Personal, Spybot, SpywareBlaster. In order to detect a suspicious program process and immediately get irrefragable information, and in case of spyware detection — to remove it, iKnow Process Scanner will be of great help.
