\r\nHow can my system get infected?
\r\nThe primary way rogue anti-virus software gets on your system is the result of you clicking on a malicious link in an advertisement or similar pop-up message. The wording contained in the advertisement is usually something alarming, designed to get your attention and attempt to convince to you scan your PC or clean it immediately with the offered tool. The names of the fake programs sound legitimate, and often, in a further attempt to make the malware appear legitimate, the programs may prompt you to pay for an annual subscription to the service. \r\n
\r\nAny kind of website could host ads for rogue anti-virus: news sites, sports pages, and social networking sites as well as "riskier" sites such as hacker blogs. Some varieties of rogue anti-virus programs will also get installed on your machine just by you visiting a website with a malicious ad or code, and you might never know you''ve been impacted. \r\n
\r\nWon''t my valid anti-virus and anti-spyware program protect my computer?
\r\nThough good anti-virus and anti-spyware programs will protect against many threats, they cannot protect against all malware threats, especially the newest ones. There are millions of different versions of malware, with hundreds more being created and used every day. It may take a day, a week, or even longer for anti-virus companies to develop and distribute an update to detect and clean the newest malware. Also nowadays many malwares install a piece of software known as a rootkit, which will hide the viruses from your antivirus software, which will keep itself from being detected.\r\n
\r\nWhat can rogue anti-virus software do to my computer?
\r\nJust about anything, Rogue anti-virus software might perform many activities, including installing files to monitor your computer use or steal credentials, installing backdoor programs, or adding your computer to a zombie botnet. The malware might even use your computer as a vehicle for compromising other systems in your home or workplace network.\r\n
\r\nRogue anti-virus software can also modify systems files and registry entries so that even when you clean off some infected files or registry keys others might remain, or even allow the infections to be restored and active again after your system is rebooted. For example, one recent rogue anti-virus program reportedly installed several malicious Trojan files, and also made over two-dozen different changes to ensure that the malware stayed on the system and stayed running. This type of malware also often blocks access to valid security sites (anti-virus and anti-spyware companies, and operating system and application update sites) so that you won''t be able to patch or clean your system by visiting those valid sites.\r\n
\r\nWhat can I do to protect my computer?
\r\n
- \r\n
- Don''t click on pop-up ads that advertise anti-virus or anti-spyware programs. Even though pop-up ads are used for valid advertising they can also be used for malicious purposes, like getting you to install fake security programs. If you are interested in a security product, search for it and visit its homepage, don''t get to it through a pop-up ad.\r\n
- If you become trapped in a webpage or pop-up that is trying to force you into accepting or downloading something just turn the computer off or restart the computer. Don''t click OK hoping that you will be able to click no later, it will be too late.\r\n
- Use and regularly update firewalls, anti-virus, and anti-spyware programs. It is very important to use and keep these programs updated regularly so they can protect your computer against the most recent threats. If possible, update them automatically and at least daily.\r\n
- Properly update operating systems, browsers, and other software programs. Keep your system and programs updated and patched so that your computer will not be exposed to known vulnerabilities and attacks.\r\n
- Keep backups of important files. Sometimes cleaning infections can be very easy; sometimes they can be very difficult. You may find that an infection has affected your computer so much that the operating system and applications need to be reinstalled. In cases like this, it is best to have your important data backed up already so you can restore your system without fear of losing your data.\r\n
- Regularly scan and clean your computer. If your organization already has configured this on your computer, do not disable it. If you need to scan your computer yourself, schedule regular scans in your programs. Also, several trusted anti-virus and anti-spyware vendors offer free scans and cleaning. Access these types of services from reputable companies and from their webpage, not from an unexpected pop-up.\r\n
