I have just got an I'net connection (I dint have one for a long time) and installed Avast! Antivirus , ZA Firewall, SUPERAntiSpyware and SpywareBlaster - all free edition - on my computer, as advised.

I installed and ran Avast as described in Avast guide here in BC and then moved the results to "chest". I had no idea what I was doing, was just following my instincts..one of the files did not move to chest, I don't know which one.

My computer seems badly infected..whenever I double-click on any local drive to open it, it gets restarted I have to use the address bar to open them and one more problem is.. when it is - the computer, that is - switched on , during the boot process it gives me a message that "Reboot and select proper boot device or insert boot media in selected boot device and press a key" , I press Ctrl+Alt+Del after I get this message and it gets restarted and then runs properly..

I also had a problem with Yahoo messenger while the Avast was still running, whenever the person I was talking to would send me an IM it will log me out and get closed...same would happen if I would try to talk to the person from inside yahoomail.

Needless to say the machine runs too slow..and one more thing I could not understand is, every now and than there is a warning on the systray saying "Virtual memory too low", is this something to worry about?

Below are some other information about my computer as advised by Belarc..

Long Live BC.
Amit.

Please download Malwarebytes Anti-Malware (v1.41) and save it to your desktop.
alternate download link 1
alternate download link 2

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

-- If Malwarebytes Anti-Malware results in any error messages, please refer to Fixes for common problems and Error Codes. Some issues with errors can be related to malware infection but others are not.

one more thing I could not understand is, every now and than there is a warning on the systray saying "Virtual memory too low", is this something to worry about?

A few queries...
I now have MBAM, SpywareBlaster , SUPERAntiSpyware and Avast Antivirus on my computer...do I need all of them? or should I remove one or more of them from my PC, If yes, how?

Is there any guide that "shows" how to use/run spywareblaster, superantispyware and most importantly Avast Antivirus..and what actions to take whenever these applications asks you what to do about a certain infection that they have found on your PC

I have Avast Antivirus' and zonealarms's free editions installed, is it advisable to buy the pro versions for both or any of them? or If I want to purchase an Antivirus software and/or firewall which one would you suggest? or do you think I am better off with the Free versions?

I can never thank you guys enough.

Still, accept my gratitude for making my life easier and my computer experience meaningful.

Long Live BC.

Those are all fine to use. In fact, that's the combo I have set up on my wife's computer. However, SUPERAntiSpyware Free does not provide real-time protection or scheduled scanning so there is no need for it to run at startup. I recommend to disable startup and use it as a separate stand-alone on-demand scanner.

I recommend taking advantage of the Malwarebytes Anti-Malware Protection Module which uses advanced heuristic scanning technology to monitor your system and provide real-time protection to prevent the installation of most new malware. This technology monitors every process and stops malicious processes before they can infect your computer. Enabling the Protection Module feature requires reqistration and purchase of a license key that includes free lifetime upgrades and support. After activation, Malwarebytes can be set to update itself and schedule scans automatically on a daily basis. The Protection Module is not intrusive as it utilizes few system resources and should not conflict with other scanners or anti-virus programs.

SpywareBlaster is a program that blocks spyware tracking cookies in Internet Explorer and any browsers that use the Internet Explorer engine, including: AOL web browser, Avant Browser, Slim Browser and Maxthon (formerly MyIE2). It also provides protection for Mozilla Firefox, Netscape, Seamonkey, and Flock. SpywareBlaster restricts the actions of potentially dangerous sites by adding a list of sites and domains associated with known spyware, advertisers and marketers to the browser's "Restricted Sites Zone" and prevents the installation of ActiveX-based spyware, adware, browser hijackers, dialers, and other potentially unwanted software. Some types of malware are known to mess with Trusted Zones, Ranges and ProtocolDefaults in for the browser.

SpywareBlaster adds sites to the restricted zones by adding the domain as a subkey under the registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains. A dword is then added to that domain named * and given a hex value of 4 to specify that it is part of the Restricted Sites Zone. More specifically, Spywareblaster sets the "killbit" on the CLSID (Class ID) of known spyware. Every program has a CLSID that is unique to the type of program. Once Spywareblaster enables (writes) those killbits they are "locked in" and any identified spyware cannot be opened. Spywareblaster writes these killbits in and then stays off until you need to re-write them again with an update.

SpywareBlaster does not run in the background. Instead it only requires installation and then enabling of all protection. After that you only have to check periodically for database updates using the built-in "Check for Updates" feature and then enable all protection again.

How to use SpywareBlaster to protect your computer
How to Install, Configure, and Use avast

Choosing an anti-virus is a matter of personal preference, your technical ability and experience, features offered, the amount of resources utilized, how it may affect system performance and what will work best for your system. A particular anti-virus that works well for one person may not work as well for another. You may need to experiment and find the one most suitable for your use. There is no universal "one size fits all" solution that works for everyone. Another factor to consider is whether you want to use a paid for product or free alternative. The same criteria applies when choosing a Firewall.

My personal choice is NOD32 Anti-Virus if choosing a paid for program or avast if choosing a free one.

No single product is 100% foolproof and can detect and remove all threats at any given time. The security community is in a constant state of change as new infections appear. Each vendor has its own definition of what constitutes malware and scanning your computer using different criteria will yield different results. The fact that each program has its own definition files means that some malware may be picked up by one that could be missed by another. Thus, a multi-layered defense using several anti-spyware products (including an effective firewall) to supplement your anti-virus combined with common sense and safe surfing habits provides the most complete protection.
