Computer Security & Viruses/lsass.exe trojan and bizrate/shopping deals on Chrome

Advertisement


Question
QUESTION: Hello there. I am having some trouble with a virus, or several, who knows. It began a while ago when Chrome would open up random tabs of adware and clickbaiting warnings when I clicked blank spaces on normally secure websites. It has now become a problem with this bizrate/shopping deals adware on any page I visit with a dollar value, mostly shopping sites like Amazon but also any review site that mentions a dollar value will activate it.
I ran hijackthis and was looking around on my log and found a known trojan "lsass.exe," but that's the only one I've identified so far, though others seem suspicious. As a point to note, the Chrome problem seems to span both this computer which is a Dell, and my Mac. After running MBAM on the PC, when it came to scanning rootkits, I received a message that MBAM was prevented from scanning rootkits, which has never happened until now. Other programs such  as avast, hitman, zemana and adwcleaner do not detect anything.
It has been nearly ten years since I have had a PC computer, mostly because of the vulnerability such as this, so I am quite rusty on how to remove trojans or viruses. Any help you can provide will be extremely appreciated.
Thank you in advance for your time. Below is my hijackthis log.

ANSWER: Hi Kelly

Please download and run Malwarebytes Anti-Rootkit tool according to the instructions here:

https://www.malwarebytes.org/antirootkit/

If items are found, run the Cleanup.  Then scan again after reboot to make sure the system is clean.

Let me know the results of the scan.

QUESTION: So the scan came back clean but my computer is still acting up. The hijack this log is still the same

Answer
Hi Kelly

I have gone through your HJT log file again, and there is no indication of malware present.  There are several essential Windows processes which show up as missing, lsass.exe among them.  What program did you run which detected it as a trojan?  You have quite a number of them installed, perhaps there is a conflict going on.  Also, you say this problem happens on Chrome across multiple devices.  Do the pop-ups occur with other browsers such as Internet Explorer or Safari?  If not, the problem lies with Chrome itself.  Do you have any pop-up blocker extensions installed?  Is Chrome up to date?  In the address bar type :
chrome://chrome/ Then press enter.  This will bring up the About Chrome page.  Make sure it is up to date (Version 46).  Next type in: chrome://extensions/ Then press enter.  See if the extensions listed are familiar to you.  Make sure there are no shopping, coupon, etc. toolbars listed.  Let me know your findings.
