My Laptop appears to have been infected with a Ransom/Highjack Virus. I cannot access the Internet with any of four browsers. I managed to rid the system of popups (using Stopzilla) but still cannot access the Web. When I try to download Combofix from a thumbdrive form another computer, I get an Error Message that my XP system is incompatible with the Combofix download, although I think I am using the correct Combofix XP link.

I'd appreciate receiving a Combofix link that is definitely compatible with XP....and a solution for downloading it to my machine. I suspect that the virus may be creating this obstacle to downloading in addition to the other problems, but I am not sure.

Thanks for your help!

Hi Stephen,

Welcome to BleepingComputer. Do you have a 64-bit Operating System?

Additionally please be aware of the following:

IMPORTANT!: No one should be using ComboFix unless specifically instructed to do so by a Malware Removal Expert who can interpret the logs. It is a powerful tool intended by its creator to be "used under the guidance and supervision of an expert. Using this tool incorrectly could lead to disastrous problems with your operating system such as preventing it from ever starting again. When issues arise due to complex malware infections, possible false detections, problems running ComboFix or with other security tools causing conflicts, experts are usually aware of them and can advise what should or should not be done while providing individual assistance. Those attempting to use ComboFix on their own do not have such information and are at risk when running the tool in an unsupervised environment.

With that said, please read the pinned topic ComboFix usage, Questions, Help? - Look here.

:step2: ComboFix logs, where should I post them?

ComboFix logs are not permitted outside the Virus, Trojan, Spyware, and Malware Removal Logsl forum and then only when requested by a Malware Response Team member. However, if you ran ComboFix on your own due to malware infection, please be aware that a ComboFix log is only one part of the disinfection process. Therefore we ask that you please read the pinned topic titled "Preparation Guide For Use Before Using Malware Removal Tools and Requesting Help". When you have done that, post the required logs to include your ComboFix log in that forum, NOT here, for assistance by the Malware Response Team Experts.


If you ran ComboFix on your own due to malware infection, please be aware that using ComboFix is only one part of the disinfection process. Preliminary scans from other tools like DDS, RSIT and GMER should be used first because they provide comprehensive logs with specific details about files, folders and registry keys which may have been modified by malware infection. Analysis of those logs allows planning an strategy for effective disinfection and a determination if using ComboFix is necessary.
Please don't send help request via PM, unless I am already helping you. Use the forums!
If you have not heard from me in 48 hours please use this and send me a PM reminder.

Hi Stephen Help,

Most likely the malware is blocking combofix. Lets see if we can find out what is wrong here. Please do not run combofix unless requested.

In the mean time I will move this topic to a more appropriate forum.

To protect your clean computer, if you cannot download and have to transfer files, please use flash disinfector.

Please download Flash_Disinfector.exe by sUBs and save it to your desktop.
  • Double-click Flash_Disinfector.exe to run it and follow any prompts that may appear.
  • The utility may ask you to insert your flash drive and/or other removable drives. Please do so and allow the utility to clean up those drives as well.
  • Hold down the Shift key when inserting the drive until Windows detects it to keep autorun.inf from executing if it is present.
  • Wait until it has finished scanning and then exit the program.
  • Reboot your computer when done.
Note: As part of its routine, Flash_Disinfector will create a hidden folder named autorun.inf in each partition and every USB drive that was plugged in when you ran it. Do not delete this folder...it will help protect your drives from future infection by keeping the autorun file from being installed on the root drive and running other malicious files.


Please Download Rootkit Unhooker Save it to your desktop.
  • Now double-click on RKUnhookerLE.exe to run it.
  • Click the Report tab, then click Scan.
  • Check (Tick) Drivers, Stealth,. Uncheck the rest. then Click OK.
  • Wait till the scanner has finished and then click File, Save Report.
  • Save the report somewhere where you can find it. Click Close.
Copy the entire contents of the report and paste it in a reply here.

Note - if you get the following warning, just ignore: "Rootkit Unhooker has detected a parasite inside itself!
It is recommended to remove parasite, okay?"

Click on Cancel, then Accept.

regards, Elise
