Emsisoft's Emergency Kit is an extremely useful tool. You may just see it referred to as EEK. Their other offerings are worth a look too.
As of about a month ago SVRT was still receiving updates.......s l o w l y. I still use it occasionally. The lack of updates to the program are a concern.
If you don't already have one, I'd strongly advocate for the creation and, maintenance of a Windows Repair Disc.
If you're able to access the Web from a suspect machine you may get results using one of the free online scanners. I've found ESET Online scanner quite reasonable. It has served very well on some extremely compromised systems. I've encountered systems where multiple scans with items in the 'Tools List'(mentioned below) have detected further Malware after the online scan. If that occurs, I generally go back to the beginning of the “list” and repeat the same scans, frequently discovering further Malware, including with the online scanner. Yes, it can be resource heavy. Personally, I consider the temporary increase in resource usage to be outweighed by the results I've seen it achieve. Once the OLS is setup you can chose to have it scan your machine on a monthly basis. It is advisable to disable any other real-time A/V A/M software while it runs. Just remember to re-enable the protection once the scan completes.
MBAR - Malwrebytes Anti-Rootkit may be useful for occasional scanning on demand.
If you have the time, please have a quick look through my 'Tools List'(in my Security Config.) Just, please don't run tools without some understanding of what they do, how to use them and, understand the potential consequences and implications for your system.
I like to take a multi-layered approach when cleaning systems. I gather information about the system first. What's working vs what's not using different tools(assuming no Ransomware obvious on the machine.) Next I speak to the system owner to establish normal usage practices plus, any changes they have noticed. Then I choose my tools. Next, I follow a strict regime of cleaning, browser resets, etc.
I always carry at least one updated scanner that will boot from DVD/LiveUSB --> Linux Shell --> Update Definitions --> Full In Depth Scan with no exclusions. These include Kaspersky Rescue Disc, ESET Sysrescue, Avira(only scan one drive or partition at a time else scan may fail,) Dr Web, etc.
I'd avoid FRST(64/32).exe unless you understand it's functions, output and, Its ability to virtually “brick” a system if not used properly. Never run a FIXLIST unless you completely understand what you're doing. If you get to the point of needing one please go to the Support Forum and request assistance in Malware Removal. The people there KNOW their “stuff.”
I neglected to mention the SysInternals Suite of tools. Again, please read up before using.
Finally, I'd suggest bumping your UAC settings to Maximum.
All the best & safe computing,
