Hi friends !<br />
<br />
What are these terms ?<br />
<br />
1. Virus, <br />
2. Worms, <br />
3. Malwares<br />
4. Spy wares<br />
5. Trojan<br />
<br />
How they are different from each other? And how can I remove them from my computer. <br />
<br />
There are many sites on the internet offering efficient products but the prices are high. I am not in the state to purchase all these products.<br />
<br />
For virus removal, there are antivirus products i.e. McAfee, Norton, Avast, AVG, Panda etc. I have purchased&amp;Symantec Norton Antivirus 2007 Purchased version.<br />
<br />
For spyware removal, there are different products. One I know is Ad-aware.<br />
<br />
I want to know if there is any good Spyware/Malware removal product that gives evaluation period to test their functionality and that is free.<br />
Or WHETHER ALL THESE REMOVALS ARE AVAILABLE IN ONE PRODUCT?<br />
<br />
Please give some details in this regard&amp;<br />
<br />
Thanks&amp;<br />

What are Virus, Malware, Spyware and Trojan ?

Anti-virus software was originally developed to detect and remove computer viruses. However, with the proliferation of other kinds of malware, antivirus software started to provide protection from other computer threats. In particular, modern antivirus software can protect from malicious browser helper objects (BHOs), browser hijackers, ransomware, keyloggers, backdoors, rootkits, trojan horses, worms, malicious layered service providers (LSPs), dialers, fraud tools, adware and spyware. Some products also include protection from other computer threats, such as infected and malicious URLs, spam, scam and phishing attacks, online identity theft (privacy), online banking attacks, social engineering techniques, Advanced Persistent Threat (APT), botnets and DDoS attacks.

Anti-Virus Apps

Various techniques are used to prevent email spam (unsolicited bulk email). No technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate email (false positives) vs. not rejecting all spam (false negatives) - and the associated costs in time and effort. Anti-spam techniques can be broken into four broad categories: those that require actions by individuals, those that can be automated by email administrators, those that can be automated by email senders and those employed by researchers and law enforcement officials.

AntiSpam

A vulnerability is a weakness which allows an attacker to reduce a system's information assurance. Vulnerability is the intersection of three elements: a system susceptibility or flaw, attacker access to the flaw, and attacker capability to exploit the flaw. To exploit a vulnerability, an attacker must have at least one applicable tool or technique that can connect to a system weakness, known as the attack surface. Vulnerability management is the cyclical practice of identifying, classifying, remediating, and mitigating vulnerabilities. Other vulnerabilities include security risks, security defects and constructs in programming languages that are difficult to use properly.
