The PC with the problem is running Windows Vista Business, Service Pk 2, 32 bit. I have AVG free for antivirus. About a week ago, I started getting an AVG warning about  a 'suspicious file', that was possibly a rootkit. It was recommended that I quarantine the file, which I did, and then AVG recommended a 'boot scan', which I did, but it didn't find anything. Since the original warning, the PC has progressively gotten worse. Simple files are slow to open. Opening Firefox can take a minute or two, and sometimes a reboot is required to get online. Once online, some websites either won't or are very slow to open. I've tried to download some troubleshooting software on this PC, and the backward grey circle just keeps spinning and if it ever turns blue and spins forward, it still at times won't load the page or software. I tried to download AdwCleaner from BleepingComp., to no avail. I have also found a file in the registry, swcustcfg, that I can't edit or delete. I worked on this file because I had seen in one of the many scans I've done, something about 'SVC: swcustcfg ->->?', being an issue, sorry I can't remember where I saw that. I'm working from a different PC now and hoping you can help me figure this out. Much thanks in advance, Roy

From Googling it seems to be a rootkit but it could also be a false positive. I would start a thread in the BC Virus Removal Forum after reading the pinned posts showing what logs to attach on your first post.

You can always do a general malware cleanup, to confirm or deny your suspicions, steps below should help you cover the basics. If after that you still haven't found anything, I would assume it is a false positive. In all honesty, AVG is no longer a viable security solution, quite some time ago it fell from the ranks, consider getting a different one. Additionally, if you are really worried, feel free to do a clean reinstall of your system after backing up the files.

 
1. Check your Programs and features and see if there are any new recently installed programs that you don’t recognize. If there are, remove them.
2. Check your task manager for any suspicious processes, if found, identify folders and try to remove them manually. Or just "Win key + R" and type %appdata%. Afterward, delete potentially malicious folders.
3. Do a full scan with anti-virus software of your choice or use Windows Defender to clean up initial infections.
4. Scan your PC with Hitman Pro, Malwarebytes, and AdwCleaner. Multiple anti-malware solutions will confirm that the threat was removed.
5. Restart your PC in normal mode and do an additional scan to confirm that the malware is gone.
 
Keep us posted on the issue solving.

Thanks for the replies and suggestions, which I will do. I'm sure there's a problem because that PC is almost totally unusable now. I will continue in the BC Virus Removal Forum after running a couple more scans. Thanks again,

The best thing to do with a possible rootkit is get a deeper look. We need to use specific tools to remove it if its there. Start at step 6
Please follow this Preparation Guide and post in a new topic.
Let me know if all went well..

New topic here
https://www.bleepingcomputer.com/forums/t/654502/trying-to-identify-a-bug-cant-download-farbarothers-from-bc/

Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.
From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.
Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRL Team member is already assisting you and not open the thread to respond.
The current wait time is 1 - 5 days and ALL logs are answered.
If HelpBot replies to your topic, PLEASE follow Step One so it will report your topic to the team members.
To avoid confusion, I am closing this topic.
