Hello, and thanks in advance for any help I can get. I've posted here once months ago with a problem I had, and now I'm back!

I'm having a problem that, after Googling the symptoms, seems to be fairly common, but I have no clue about how to proceed. Earlier today, I began getting alerts from a program claiming to be Windows Defender (which, as unsavy as I may be, I was able to tell almost immediately it wasn't the real deal) alerting me about attacks on my computer, and telling me to "Enable Protection."

I'm using Windows XP, and I have ZoneAlarm Security Suite protecting my computer. The scans haven't picked up any problems, so again, I have no idea what to do from this point. Please help!

^Thanks and sorry for having to move my topic.

Just as an update, my computer is running extremely slow now. I just tried booting it up, and it is completely unresponsive after loading the desktop--all I can do is move my cursor around...I think i'm going to try rebooting it and loading an anti-malware program I've seen recommended on here, but I'd really appreciate any help anyone can give me!

Update: So I downloaded Malwarebytes Anti-Malware, but I'm having a hard time even installing it. It gets to 99% installed, and then my computer stops responding, and I continue to get false Windows Defender alerts, urging me to "Enable Protection" on my PC. Please help! I have no clue what I'm supposed to do if I can't even get a new program installed to get this thing off..

Another update: It looks like Malwarebytes did in fact install, but I can't open it. I double click on it, and nothing happens. Also, when I pull up the Windows Task Manager, there are seven separate svchost.exe's displayed.

Some types of malware will disable Malwarebytes Anti-Malware and other security tools. If MBAM will not install, try renaming it first.
  • Right-click on the mbam-setup.exe file file and rename it to mysetup.exe.
  • Double-click on mysetup.exe to start the installation.
  • If that did not work, then try renaming and changing the file extension. <- click this link if you do not see the file extension
  • Right-click on the mbam-setup.exe file, rename it to mysetup and change the .exe extension to .scr, .com, .pif, or .bat.
  • Then double-click on mysetup.scr (or whatever extension you renamed it) to begin installation.
If after installation, MBAM will not run, open the Malwarebytes' Anti-Malware folder in Program Files.
  • Right-click on mbam.exe, rename it to myscan.exe.
  • Double-click on myscan.exe to launch the program.
  • If that did not work, then try renaming and change the .exe extension in the same way as noted above.
  • Double-click on myscan.scr (or whatever extension you renamed it) to launch the program.
If using Windows Vista, refer to How to Change a File Extension in Windows Vista.

Be sure to update MBAM through the program's interface (preferable method) or manually download the definition updates and just double-click on mbam-rules.exe to install. Then perform a Quick Scan in normal mode and check all items found for removal. Don't forgot to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the report in your next reply.

Note: MBAM uses Inno Setup instead of the Windows Installer Service to install the program. If installation fails in normal mode, try installing in safe mode. Doing this is usually not advised as MBAM is designed to be at full power when running in normal mode and loses some effectiveness for detection & removal when used in safe mode. For optimal removal, normal mode is recommended so it does not limit the abilities of MBAM. Therefore, after completing a scan it is recommended to uninstall MBAM, then reinstall it in normal mode and perform another Quick Scan.
