Steve, the version of the programs for these scans are not meant to be 'resident.' They were tools to scan and clean the system. Some of them will have paid versions that you can purchase and set up on the system.

It would serve no purpose for you to run DDS or GMER because each has to be reviewed and 'handled.

We don't advocate anyone running Combofix without supervision. Other tools we may have use such as scans for rootkits are specific to use when appropriate.

You can download and run a free Mbam scan if you want. But the free one won't update on the system nor later on if you attempt to update it.

The Eset scan is still on the system under Manage Add ons.

Others have asked this same question. My experience has been twofold:
1. Running random scans and cleaning programs usually results in additional problems.
2. Running a scan-such as Mbam, even if it finds and removes malware, does not mean all the malware has been found- or removed.
=======================================
Here are some suggestions that you can download, which will help keep the system clean- and they are all free!
Tips for added security and safer browsing: (Links are in Bold Blue)

1. Browser Security
   [o] Safe Settings (Please ignore the suggestion to use the Registry Editior in this section "Creating a Custom Security Zone")
   [o] ZonedOut. This manages the Zones in Internet Explorer. (For IE7 and IE8, Windows 2000 thru Vista. No Windows 7)
   [o] Replace the Host Files
   [o] Google Toolbar Pop Up Blocker
   [o]Web of Trust (WOT) Site Advisor. Traffic-light rating symbols show which rate the site for Trustworthiness, Vendor Reliability, Privacy, Child Safety.
   
2. Have layered Security:
   [o]Antivirus :(only one):Both of the following programs are free and known to be good:
   [o]Avira-AntiVir-Personal-Free-Antivirus
   [o] [o]Avast-Free Antivirus
   [o]Firewall (only one): Use bi-directional firewall. Both of the following programs are free and known to be good:
   [o]Comodo
   [o]Zone Alarm
   
3. Antimalware: I recommend all of the following:
   [o]Spywareblaster: SpywareBlaster protects against bad ActiveX.
   [o]Spybot Search & Destroy
   
4. Updates: Stay current:
   [o] the Microsoft Download Sitefrequently. All updates marked Critical and the current SP updates.
   [o]Adobe Reader Install current, uninstall old.
   [o]Java Updates Install current, uninstall old.
   
5. Tracking Cookies
   Reset Cookie:
   [o]For Internet Explorer: Internet Options (through Tools or Control Panel) Privacy tab> Advanced button> check 'override automatic Cookie handling'> check 'accept first party Cookies'> check 'Block third party Cookies'> check 'allow per session Cookies'> Apply> OK.
   [o]For Firefox: Tools> Options> Privacy> Cookies> check ‘accept Cookies from Sites’> Uncheck 'accept third party Cookies'> Set Keep until 'they expire'. This will allow you to keep Cookies for registered sites and prevent or remove others. (Note: for Firefox v3.5, after Privacy click on 'use custom settings for History.')
   I suggest using the following two add-on for Firefox. They will prevent the Tracking Cookies that come from ads and banners and other sources:
   AdBlock Plus
   Easy List
   [o]For Chrome: Tools> Options> Under The Hood> Privacy Section> CHECK 'Restrict how third party Cookies can be used'> Close.
   
6. Do regular Maintenance
   [o] Temporary File Cleaner
7. Restore Points:
   [o]See System Restore Guide
8. Safe Email Handling
   [o] Don't open email from anyone you don't know.
   [o] Don't open Attachments in the email. Safe to your desktop and scan for viruses using a right click
   [o] Don't leave your personal email address on the internet. Have a separate email account at one of the free web-based emails like Yahoo.

Please let me know if you find any bad link.

(The 'real' reason, of course, that we have the programs removed is because if everyone used them and knew how to handle the log entries, I'd be out of my volunteer job!)

You're very welcome, Steve. Stay safe and enjoy your computing!
