I'm not entirley sure what the problem is - but I'm convinced there's something wrong with my PC

The other week the system repair xp trojan installed itself onto my PC, but by following instructions from here I seemed to get rid of it.
According to scanners such as Maleware Bytes, Spybot, SUPERAntiSpyware, & Virgin Media Security I have now no malicious files on my PC (Just Spyware Cookies)


Yet I keep encounting problems, such as:
  • Before I turned on my monitor to find Outlook Express had composed 84 e-mail's to Virgin Media's fraud scamming dept. (This does seem to coincide with a Virus Scan by Virgin software)
  • Internet Explorer will crash while I'm in the middle of something (Like writing this post <_< )
  • I had a My Heritage Add-on for IE, which seems to have completley disappeared
  • Everytime I restart IE goes back to default settings
  • The other day I tried to run a scan with Virgin Media, which terminated itself. The same happened with MalWare Bytes
  • Also I could be using a program & it will suddenly disappear with no error message given.
    Sometimes the program magically reappears hours later
  • My Internet connection will randomly go off as well - but I'm not sure if this connected to this problem

Does it sound like I'm infected with something? Or I just have a tempermental PC?

Hello, Important Note: Your version of Java is out of date. Older versions have vulnerabilities that malicious sites can use to exploit and infect your system.Please follow these steps to remove older version Java components and update:
  • Download the latest version of Java Runtime Environment (JRE) Version 7 and save it to your desktop.
  • Look for "Java Platform, Standard Edition".
  • Click the "Download JRE" button to the right.
  • Read the License Agreement, and then check the box that says: "Accept License Agreement".
  • From the list, select your OS and Platform (32-bit or 64-bit).
  • If a download for an Offline Installation is available, it is recommended to choose that and save the file to your desktop.
  • Close any programs you may have running - especially your web browser.
Go to Posted Image > Control Panel, double-click on Add/Remove Programs or Programs and Features in Vista/Windows 7 and remove all older versions of Java.
  • Check (highlight) any item with Java Runtime Environment (JRE or J2SE) in the name.
  • Click the Remove or Change/Remove button and follow the onscreen instructions for the Java uninstaller.
  • Repeat as many times as necessary to remove each Java versions.
  • Reboot your computer once all Java components are removed.
  • Then from your desktop double-click on jre-7-windows-i586.exe to install the newest version.
  • If using Windows 7 or Vista and the installer refuses to launch due to insufficient user permissions, then Run As Administrator.
  • When the Java Setup - Welcome window opens, click the Install > button.
  • If offered to install a Toolbar, just uncheck the box before continuing unless you want it.
  • The McAfee Security Scan Plus tool is installed by default unless you uncheck the McAfee installation box when updating Java.
Note: The Java Quick Starter (JQS.exe) adds a service to improve the initial startup time of Java applets and applications but it's not necessary.
To disable the JQS service if you don't want to use it:
  • Go to Start > Control Panel > Java > Advanced > Miscellaneous and uncheck the box for Java Quick Starter.
  • Click Ok and reboot your computer.


Similarly Update to Adobe Reader X (10.1.0)
Note UN check the box so you do not install the toolbar,unless you really want it..

Free! Google Toolbar search Google from any web page, block pop-ups

Yes, install Google Toolbar - optional

Thanks very much for all your help. :thumbup2:

I imagine that original virus/trojan entered my computer via Java, I seem to recall using a Java applet on a website before IE crashed & the PC started playing up.

IE seems to be running a lot smoother now, so let's hope this has solved the problem

Thanks again

You are welcoeme!! Quite likely that that was the leak.

If there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Start > Run and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista Users can refer to these links: Create a New Restore Point and Disk Cleanup.

Tips to protect yourself against malware and reduce the potential for re-infection:Avoid gaming sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs. They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Many malicious worms and Trojans spread across P2P file sharing networks, gaming and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications. Read P2P Software User Advisories and Risks of File-Sharing Technology.

Keeping Autorun enabled on USB and other removable drives has become a significant security risk due to the increasing number of malware variants that can infect them and transfer the infection to your computer. To learn more about this risk, please read:

OK< lets do this again

Please download the TDSS Rootkit Removing Tool (TDSSKiller.exe) and save it to your Desktop. <-Important!!!
Be sure to download TDSSKiller.exe (v2.5.9.0) from Kaspersky's website and not TDSSKiller.zip which appears to be an older version 2.3.2.2 of the tool.
  • Double-click on TDSSKiller.exe to run the tool for known TDSS variants.
    Vista/Windows 7 users right-click and select Run As Administrator.
  • If TDSSKiller does not run, try renaming it.
  • To do this, right-click on TDSSKiller.exe, select Rename and give it a random name with the .com file extension (i.e. 123abc.com). If you do not see the file extension, please refer to How to change the file extension.
  • Click the Start Scan button.
  • Do not use the computer during the scan
  • If the scan completes with nothing found, click Close to exit.
  • If malicious objects are found, they will show in the Scan results - Select action for found objects and offer three options.
  • Ensure Cure (default) is selected, then click Continue > Reboot now to finish the cleaning process.
  • A log file named TDSSKiller_version_date_time_log.txt (i.e. TDSSKiller.2.4.0.0_27.07.2010_09.o7.26_log.txt) will be created and saved to the root directory (usually Local Disk C:).
  • Copy and paste the contents of that file in your next reply.


And another Rootkit scan.

Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning

Okay - The first one you suggested, doesn't seem to load up (even after renaming it) - but looks like it does make my pc slow down.

The second pops up a messgae:

& then scans, and comes up with no problems & a blank log file.
