A harmful virus can delete important files, alter user settings, corrupt your system registry and cause your computer to become otherwise inoperable.
Cleanup Antivirus can attach itself to your computer without your knowledge of being there. You probably won't even recall how it got in there in the first place. It spreads in your computer with the help of Trojans.

Instructions

1: Click the "Start" button, right-click on "My Computer" and select "Properties." Click the "System Restore" tab and check the "Turn off System Restore on all drives" box. Most anti-virus programs do not scan the System Restore volume, allowing viruses and other malware to later re-infect your system. Turning off the System Restore feature prevents this from occurring.

2: Download and install an anti-virus program. Anti-virus programs scan your computer's files for bits of code that match a virus definitions database. Anti-virus programs delete, quarantine or clean files containing malicious code according to the anti-virus program's default settings or your user preferences. See Resources for a list of available programs.

3: Update the anti-virus software. You should regularly update the database of virus definitions that the anti-virus program uses to determine if a file contains a virus. If your database of virus definitions is out of date, you are leaving your computer at risk for infection.

3: Run a "Complete" or "Deep" file scan to detect and remove the virus. Many anti-virus programs allow you to run a "Smart scan," which scans only recently changed or particularly virus-prone files on your computer. If the virus is dormant on your computer or resides in a directory not checked by the "Smart scan," the anti-virus program will not detect the virus. If possible, instruct the anti-virus program to scan all drives on the computer, including any removable media and flash drives. If prompted to delete or clean an infected file, opt to clean the file first. If the anti-virus program cannot clean the file, delete the file to permanently remove it from your computer.

5: Reboot your computer when the anti-virus scan is complete. Allow the operating system to load. Click the "Start" button, right-click on "My Computer" and select "Properties." Click on the "System Restore" tab and uncheck the "Turn off System Restore on all drives" box to re-enable the System Restore feature.

Most Internet users are very aware of the dangers of spyware, adware and malicious software and may have taken precautions against such attacks by installing suitable antivirus software. However another threat exists known as rogue antivirus, which is really a fake antivirus. You may find a search for free antivirus download for pc and free antivirus softwares download useful.

This fake scareware rogue antivirus appears to be genuine and even goes under the name of MS Antivirus or Spyware Protect 2009. (This is not to be confused with the legitimate Microsoft Antivirus and Windows LiveOneCare or the current genuine Microsoft Security Essentials anti-malware program).

MS Antivirus comes under many titles including Security Tool and Total Security, VistaAntiMalware2010, AntiSpyware2010, Internet Security2010, XP Antivirus and many more. Why not give free antivirus download for pc and free antivirus softwares download a try?

MS Antivirus operates by running a scan on your computer, giving a false report regarding infections found then requesting you to click on a link to remove it. Whether you click on a button to cancel or remove, a download box will still pop up.

Everything is designed to scare the user to click on the purchase button. Pop-ups continually appear with a request to register to have them fixed.

While many variants of MS Antivirus do not usually harm your computer system, or steal your information, they do cause great inconvenience to the computer user.

Some variants however are quite harmful as they display popups as soon as the user attempts to start an application or navigate the hard drive. This is done by modifying the Windows registry and because the screen is clogged with continual popups, renders your computer unusable.

It can also disable genuine antivirus programs and block access to known spyware removal sites, as well as redirect you to a false Google search page. So what can you do about it?

1. Keep your ear to the ground and be alert to events and news about security.

2. It pays to be always vigilant to the point of paranoia when on the Internet and to be aware of suspicious activities, for example your computer unusually slow

When a trojan infects a computer, it can change settings, cause pop-ups to display, redirect search engine results or decrease a computer's performance. Users can cure current infections and prevent new ones with anti-virus software.

Identification

Trojans take their name from the historical Trojan horse because this type of file frequently poses as legitimate file, such as anti-virus software. Anti-virus programs can detect trojans even when the infection hides in a legitimate location. Anti-virus programs will also delete tracking cookies, or small text files that website servers exchange with the browser to provide information such as the user's location.
Solution

Users should install a full anti-virus program and run a scan to detect and remove trojans. Avast! and AVG both provide free anti-virus programs with frequent virus definition updates. In addition to this, anti-malware programs such as Spybot or Malwarebytes' Anti-Malware can scan for computer infections that may cause pop-ups and tracking cookies.

Considerations

Tracking cookies do not contain personally identifiable information such as names or addresses. They can be beneficial by providing custom content such as a local news feed. Some users, however, prefer to delete these cookies using an anti-virus program or browser utilities, and doing so does not impede Internet usage.

An e-mail virus that is believed to have originated in Japan has been propagating around the Internet on Thursday morning, infecting thousands of computers.

The FBound-C virus is very similar to the FBound-A and FBound-B viruses, said Alex Shipp, senior antivirus technologist at e-mail outsourcing firm Messagelabs, which operates a virus scanning service for its customers. "It's just different enough to get past signature scanners," he told ZDNet UK.

However, Shipp added, antivirus companies are updating their signature files, and the fact that the virus was first discovered at 2:00 a.m. GMT means that companies and individuals in Europe, Africa and America should have time to update their software. "So although we've seen lot of copies this morning, we expect to see it nipped in the bud," said Shipp.

Antivirus firms say the virus is likely to have originated in Japan, or at least seems to be targeting Japanese users. "We started seeing it arrive from the Asia Pacific region," said Shipp. "First Japan, then China and Hong Kong."

Graham Cluley of antivirus company Sophos agreed. "Most viruses are monolingual," said Cluley. "This can make people less likely to open them. If you receive a virus from Belgium with a Belgian subject line, you're going to be more suspicious." FBound.C, said Cluley, was written in such a way that if it believes the recipient is in Japan it adds a Japanese subject line. Otherwise, the subject line says in English: "Important".

The virus is contained in an attachment called patch.exe, presumably designed to make people click on it believing that it is a software patch, said Cluley. "They're exploiting people's paranoia," he said. "But people really should have learnt by now not to click on email attachments. They should go to software companies for patches."

Shipp noted that the virus does not rate highly in the social engineering stakes, "but it seems to be doing quite well anyway." Within eight hours of first detecting the virus, Messagelabs had caught more than 2,000 copies. This indicates that the virus is spreading faster than the recent Myparty virus.
