Here are my recommendations for free software to protect your computer. 1. Install a good (Free) Anti-Virus package. 1. -> Avira Antivir 2. -> Avast 4 3. -> AVG 8.5 AVAST 4 Home Edition had the highest rate of zoo virus detection (92%), followed by AntiVir PersonalEdition Classic at 85% and AVG Free Edition at 81%. However, AVAST's higher zoo detection was offset by a correspondingly higher rate of false positives, 9 total compared to AntiVir at only 2. Conversely, AVG scored the lowest in both categories, racking up 11 false positives and also is very heavy on resources. Avira AntiVir is my top pick if you're looking for the best protection against viruses. It is very light on resources and the detection rate of viruses and rootkits is outstanding. However, it does not include e-mail scanning which is only available in the paid version. The lack of an e-mail scanner just means that AntiVir won't warn you of infected emails before you open them. However, should you open an infected email; AntiVir will still spring into action, so it doesn't mean that you're not protected from email-based infections. Although AntiVir has advertisements that appear with every update, these ads can be disabled -> HERE! 2. Install a good Anti-Spyware package. One of the easiest ways to be infected is to download freeware/shareware programs which come laden with malware - this includes allowing websites to install browser plug-ins or ActiveX controls. Install - > SpywareBlaster SpywareBlaster prevents the installation of many so-called spyware, adware and malware programs by disabling the CLSIDs of popular spyware ActiveX controls, and also prevents the installation of any of them via a webpage. This allows you to run Internet Explorer with Active-X enabled, but it will never download or even prompt you for any of the known Bad ActiveX controls. All other Active-X controls or plug-ins will work fine. The SpywareBlaster database contains information on these known spyware Active-X controls and can be updated with the click of a button. The application windows displays a list of all controls that it is able to detect (this is not a list of what was found on your computer). The program cannot detect if you have any of the known objects already installed, but if you do, they will be disabled. SpywareBlaster is passive protection. It plugs the holes that spyware and other potentially unwanted software use to get in to your system. As such, there is no running process - and no CPU and memory usage either. All you have to do is remember to update SpywareBlaster once a week, and enable the latest protection. Note: After installation, SpywareBlaster is not running and you never hear anything out of it; therefore it’s easy to neglect the updates. Since I tend to forget it, I have scheduled a Task to run it every Wed. and when it pops up, I simply update it and then close it.. 3. Install Host-Based Intrusion Prevention Software (HIPS) that prevents the execution of unknown software on your system. 99% of all threats have one thing in common - they are set to execute from one or more of the "Run" keys in the Registry. To protect against these; HIPS functions give you the ability to stop all unrecognized programs from running on your computer unless you say so, making it possible to protect yourself against Zero day new attacks. Of course known, safe programs will be allowed to run, no problem. This is different to a pure Antivirus program - these let any program run, unless they know it is a virus. This means that it must have that exact threat in its database before it can do anything about it. Your antivirus will completely ignore programs it does not recognize - which unfortunately includes new viruses. -> Comodo BOClean protects your computer against trojans, malware and other threats.

returnil virtual system. It's the best security system available. virus/trojans/spyware might defeat your antivirus/antispyware but it won't defeat returnil. Even new/unknown viruses will not defeat returnil.
