I run windows XP sp3. Today I was researching phone cases in Firefox through google image search and a pop up quickly appeared and disappeared. I did not click on it. I immediately noticed a new "security defender" icon on my desktop. I did not run the program. At this point I tried to run adaware but it crashed during startup and would not load (I now know this is from the rootkit). Running malwarebytes yielded the same result. I then disabled internet access and on another computer searched forums for possible solutions and came across the majorgeeks malware removal guide. I followed all steps in the removal guide and downloaded the required software and transferred the files to the infected computer via USB. Superantispyware (install version and non-install version) would install but would crash before the scan started. To run the software again would require it to be uninstalled and reloaded but with the same results. Loading malwarebytes had a similar result. I was able to run combofix and identified rootkit.zeroaccess inserted into the tcp/ip stack. The combofix scan was completed. Next, RootRepeal was run successfully. Attempting to run MGTools (directly from C:/) causes an almost immediate BSOD followed quickly by a complete system shutdown. I then installed superantispyware and malwarebytes successfully and ran system scans. Each detected several trojans. All were quarantined. I have attached all scan logs to this post. The SAS and MBAM logs are from after the combofix and rootrepeal were run. At this point I cannot access internet via wifi. Error msg reads - the proxy server is refusing connections. Do I need to rerun combofix again to correct this issue? Have I removed the rootkit? What should I do next? Thank you for your help!
