Threat Metric
The Threat Meter is a malware assessment that SpywareRemove.com's research team is able to
give every identifiable malware threat. Our Threat Meter includes several criteria based off of
specific malware threats to value their severity, reach and volume. The Threat Meter is able to give
you a numerical breakdown of each threat's initial Threat Level, Detection Count, Volume Count,
Trend Path and Percentage Impact. The overall ranking of each threat in the Threat Meter is a basic
breakdown of how all threats are ranked within our own extensive malware database. The scoring for
each specific malware threat can be easily compared to other emerging threats to draw a contrast in
its particular severity. The Threat Meter is a useful tool in the endeavor of seeking a solution to
remove a threat or pursue additional analytical research for all types of computer users.
The following fields listed on the Threat Meter containing a specific value, are explained in detail below:
Threat Level: The threat level scale goes from 1 to 10 where 10 is the highest level of severity and 1 is the lowest level of severity. Each specific level is relative to the threat's consistent assessed behaviors collected from SpyHunter's risk assessment model.
Detection Count: The collective number of confirmed and suspected cases of a particular malware threat. The detection count is calculated from infected PCs retrieved from diagnostic and scan log reports generated by SpyHunter.
Volume Count: Similar to the detection count, the Volume Count is specifically based on the number of confirmed and suspected threats infecting systems on a daily basis. High volume counts usually represent a popular threat but may or may not have infected a large number of systems. High detection count threats could lay dormant and have a low volume count. Criteria for Volume Count is relative to a daily detection count.
Trend Path: The Trend Path, utilizing an up arrow, down arrow or equal symbol, represents the level of recent movement of a particular threat. Up arrows represent an increase, down arrows represent a decline and the equal symbol represent no change to a threat's recent movement.
% Impact (Last 7 Days): This demonstrates a 7-day period change in the frequency of a malware threat infecting PCs. The percentage impact correlates directly to the current Trend Path to determine a rise or decline in the percentage.

Trojan.Zbot is a broad subtype of backdoor Trojans that steal passwords and other confidential information, while also weakening the security of the infected PC. Because Trojan.Zbot encompasses many different Zbot variants, such as Trojan-Spy.Win32.Zbot.apqa, TSPY_ZBOT.FAZ, Trojan-Spy.Win32.Zbot.boux or Trojan-Spy.Win32.Zbot.bfur, the symptoms of a Trojan.Zbot infection can be very diverse or, in some cases, nonexistent. However, SpywareRemove.com malware research team have found all variants of Trojan.Zbot to be extremely dangerous, and the majority of Trojan.Zbot infections will seek to harvest specific information that's related to account logins or finances. If you suspect that a Trojan.Zbot Trojan has compromised your computer, be ready to take extreme measures, including use of advanced anti-malware software, to remove Trojan.Zbot and shut down the violation of your privacy.
How Trojan.Zbot Creeps into Your PC with Zero Suspicion
Trojan.Zbot Trojans and other forms of backdoors have been noted for using deceptive methods of infecting PCs, but SpywareRemove.com malware researchers have noticed a particular rise in advanced social engineering tactics to spread Trojan.Zbot. Common ways of being infected by Trojan.Zbot can include:
- Social networking links. Variants of Trojan.Zbot may disguise themselves in the form of fake video or pictures files, or use compromised accounts to send themselves to social contacts. Facebook is an especially popular target for certain variants of Trojan.Zbot, such as TSPY_ZBOT.FAZ. Never download a file, even if it's sent by a friend, unless you're certain that it's legitimate.
- Fake software updates. Adobe Flash updates, codec updates and general movie player updates are all exploited to install Trojan.Zbot and other Trojans. Never acquire software updates from unofficial or disreputable sources, and always navigate to official websites by typing the URL rather than following links that have been given to you.
- Fake infection alerts. These warnings are often embedded in fake online scanners that trigger automatically, and are a primary distribution method for rogue security software, as well as Trojans that install scamware.
What Happens in the Aftermath When Trojan.Zbot Hits
Variants of Trojan.Zbot Trojans may show different symptoms, and many may show no symptoms at all. However, SpywareRemove.com malware experts have found the following traits to be extremely common, based on standard operating procedures for typical Trojan.Zbot infections:
- Trojan.Zbot will launch itself and remain active without permission and may use some method to conceal itself, such as by renaming itself after a normal system file or even by using advanced techniques to inject its code into system processes. These hiding attempts can be noted if you look for extra memory processes or unusual memory usage for a process.
- Trojan.Zbot may open your network ports and disable or alter your firewall to allow free networking traffic.
- Other security programs besides your firewall may also be blocked by Trojan.Zbot; these blockades may use fake error messages to trick you into thinking that these programs are infected.
- Browser hijacks may redirect you to phishing websites or other harmful sites that try to steal private information, such as your credit card number or account password. Browser hijacks can be noticed when your web browser redirects itself to a strange website, when your homepage settings are changed or when pop-ups appear without explanation.
Because most Trojan.Zbot Trojans that SpywareRemove.com malware researchers are familiar with have a tendency to focus on stealing passwords and financial data (such as Bank of America account data), you should consider any possible Trojan.Zbot attack an extreme threat and react with appropriate caution.

I'm using Kaspersky in both my laptop and desktop. I previously used the antivirus version and it didn't use that much memory as much as the internet security version doesn. So, i again installed the antivirus version but I don't see much difference. My desktop has only 256RAM. I can't do anything else if I open 2 application. But I can't rely on other antivirus softwares because their detection rate suck. (believe me, I'm an antivirus pro). So. What should I do now?
When I first started to expeirence the dreaded Win 7 Anti Virus pop ups, I created a new admin profile and deleted the infected one. The profile is working fine but my fire wall is turned off. It gives me a error message when I try to turn it back on. I tried to delete its registry entires but there is only about 5 of them and when I right click on them the delete option is not available.<br />When I click to the space to the right it says "default" and there is a option available when I right click to delete. These are the five entries that I see.<br />HKEY_CLASSES_ROOT<br />HKEY_CURRENT_USER<br />HKEY_LOCAL_MACHINE<br />HKEY_USERS<br />HKEY_CURRENT_CONFIG<br />The message to the right of these entries does not change when I click on the different HKEY's. Should I delete this message to the right? Is this the virus? What should I do?
I have this virus in my pc and I run the pc with microsoft security essentials. It recognized the virus and says it's removed but when I run the antivirus again it's always the same. I also can't open antivirus websites so my question is can I install spyhunter without unninstal microsoft security essentials or should I unninstal it?
Thanks and sorry for my english
