I am also attaching the same log below in case it is required...........

Thanks in advance

Welcome to the BleepingComputer Forums.

Since it has been a few days since you scanned your computer with HijackThis, we will need a new HijackThis log. If you have not already downloaded Random's System Information Tool (RSIT), please download Random's System Information Tool (RSIT) by random/random which includes a HijackThis log and save it to your desktop. If you have RSIT already on your computer, please run it again.

• Double click on RSIT.exe to run RSIT.
• Click Continue at the disclaimer screen.
• Please post the contents of log.txt.

Thank you for your patience.

Please see Preparation Guide for use before posting about your potential Malware problem.

If you have already posted this log at another forum or if you decide to seek help at another forum, please let us know. There is a shortage of helpers and taking the time of two volunteer helpers means that someone else may not be helped.

Please post your HijackThis log as a reply to this thread and not as an attachment. I am always leery of opening attachments so I always request that HijackThis logs are to be posted as a reply to the thread. I do not think that you are attaching anything scary but others may do so.

While we are working on your HijackThis log, please:

• Reply to this thread; do not start another!
• Do not make any changes on your computer during the cleaning process or download/add programs on your computer unless instructed to do so.
• Do not run any other tool until instructed to do so!
• Let me know if any of the links do not work or if any of the tools do not work.

• Do not run any other programs or open any other windows while doing a fix.
• Ask any questions that you have regarding the fix(es), the infection(s), the performance of your computer, etc.

Thanks.

Sorry for the trouble

Thanks in advance

I have some very bad news for you. Since you said your system is infected with Virut, I must give you this information. Virut is a Polymorphic File Infector which is a virus that changes its virus signature (i.e., its binary pattern) every time it replicates and infects a new file in order to keep from being detected by an antivirus program. Virut infects .EXE and .SCR files. It opens a Backdoor by connecting to a predefined IRC Server and waits for commands from the remote attacker - for example to download/run more malware on the compromised computer. Emails may be harvested as well. This latest variant may also search for htm, html, asp and php files on the drives and modifies them by inserting an iframe that points to a malicious website. Virut is capable of infecting all the machine's executable files (.exe) and screensaver files (.scr). However, the problem is that the virus has a number of bugs in its code, and as a result, the files are corrupted beyond repair.

Miekiemoes regarding Virut:

This one is being spread via illegal sites (cracksites/keygens etc) and P2P Software (limewire, shareaza).
The P2P software makes sense, because many people are infected with this virus. So, since this virus infects legitimate files, the files being shared via P2P software such as limewire are also infected. So I'm pretty sure that more than 50% of the files being shared through P2P nowadays is infected with Virut unfortunately.

Although some programs such as Malwarebytes will clean the reader_s.exe from your computer, the damage has already been done.

Security experts suggest that a format and clean install or destructive recovery, if you have an OEM recovery partition, is the best way to clean the infection. It is the best and safest way to return the machine to its normal working state. DO NOT do a repair install.

Backup all your documents and important items (personal data, work documents, etc) only.

DO NOT backup any executable files (softwares) and screensavers (*.scr). Avoid backing up compressed files (zip/cab/rar) files that have .exe or .scr files inside them. Virut can penetrate and infect .exe files inside compressed files too. Files with these extensions SHOULD NOT BE BACKED UP:

• .exe
• .scr
• .htm
• .html
• .xml
• .zip
• .rar

It attempts to infect any accessed .exe or .scr files by appending itself to the executable.

Important: Do not back up to another machine as it may become compromised. Burn to DVD/CD or to an external drive which has nothing else on it so that you can format it if it happens to become infected from the backups.
