Our recommended software:

There are not many good anti-malware software"s with high detection ratio. Our malware research team recommend to run several applications, not just one. These antimalware software"s which listed below will help you to remove all pc threats like HTML/ScrInject.B.Gen.

In the previous articles of the cycle on cleaning the computer, we talked about two things: how to clean the PC from dust inside, and how to prevent infection when installing and configuring programs.

Are you infected?

... The opinion from the category “if you do not install antiviruses, then there will be no viruses” is still popular. The fact that this, to put it mildly, is far from the truth, is unnecessary to say - of course, if we are talking about a Windows computer, and Windows is installed on the vast majority of PCs and laptops. Of course, by installing Linux, you will automatically save yourself from tens of thousands of Trojans, but in terms of convenience, this OS is still far from Windows, even with all its undeniable advantages.

Yes, there will be viruses, but not only them: various trojans, malicious codes, phishing sites and adware programs... And there is no end in sight to this, on the contrary, every year the number of people who want to do harm increases exponentially. Remember what happened at least ten years ago: there was no such abundance of filth.

Having an “expensive and super-duper-cool” anti-virus package – or a package internet security- never protects you by 146% of everything. Adware (advertising infections) and malware (trojans, etc.) have already learned how to infiltrate a computer bypassing all protections, and no matter how cool a system administrator you are, don’t be arrogant: even the most hardened users were pierced with a bang in the author’s memory. And all why?

Because no protection will save you from the "laying between the keyboard and the chair": from the average user.

ESET, a leader in the development of antivirus software, reports that in June, increased activity of the JS/TrojanDownloader.Pegel.BR Trojan was detected using the ThreatSense.Net rapid alert system.
This malware is a script that is added to web pages and automatically redirects visitors to infected sites. After that, loading and execution malicious code on unsecured computers. This threat, referred to by ESET experts as JS/TrojanDownloader.Pegel.BR, is spreading across Europe at a very fast pace. In percentage terms, in relation to the total number of infected computers, its share is already 2.29%, which provided the Trojan with the fifth place in the world ranking of threats. Despite the fact that the JS/TrojanDownloader.Pegel.BR malware has not yet spread in Ukraine, ESET experts strongly recommend that Ukrainian users be extremely careful when downloading files from the Internet, as well as update ESET NOD32 Antivirus and ESET products smart security up to 4.2 version to ensure maximum protection computer.
In June, the Conficker family continues to be active. Win32/Conficker for a month holds the palm among malware in the global (9.79%) and Ukrainian (19.42%) threat ratings. This network worm spreads through a vulnerability in Windows OS, which resides in the remote procedure call (RPC) subsystem, as well as through unprotected public folders and removable storage media. Also widespread is the INF/Conficker threat, another member of a well-known family. Using the autorun.inf file, this malware spreads the latest variations of the Conficker worm to infect PCs. A large number of infected computers around the world, including in Ukraine (1.47% and 1.66%, respectively) provides this threat with a leading position in the malware ratings.
ESET experts strongly recommend that users securely protect personal data, as such threats as Win32/Agent, Win32/PSW.OnLineGames and Win32/Tifaut, designed to steal confidential information, are not inferior to their positions. Users should also beware of INF/Autorun malware, which takes advantage of the autorun capability on removable media and launches malware every time a removable media is connected to the computer, as well as last month's "new" Win32/Sality, which is a polymorphic virus that modifies EXE files and SCR and disables antivirus programs.
The beginning of the summer could not but "please" users with new viruses. In the TOP-10 of the global threat rating in June, two "new" products are presented - Win32/Qhost (1.16%) and HTML/ScrInject.B (0.84%). The Win32/Qhost Trojan is distributed using Email and gives attackers access to the infected computer. Before launching, this threat copies itself into Windows folder%system32% and then modifies the host file to redirect traffic to the attacker's domains. HTML/ScrInject.B threat detects web page html with obfuscated script or iframe tags that automatically redirect to malware downloads.
According to ESET experts, due to the increase in Internet fraud and the complexity of virus writing technologies, users should be extremely careful when working on the Internet, as well as when using removable storage media. To effectively protect personal data and confidential information, ESET recommends that you regularly update operating system, as well as use reliable anti-virus solutions with up-to-date signature databases that can provide comprehensive computer protection.
