Believe this no-or-slow boot problem is due to a virus

Today was on two pages in internet explorer - strangely something like news and Wikipedia - and got diverted for a while with a phone call. When I returned the damage was done. It was not possible to to close the pages, but waited quite a while. The only thing that worked was task manager, which was already open but suddenly expanded about 5 minutes after I clicked on it.
 
I should have run MalwareBytes first without shutting down the computer, for when I did it would not boot completely into any mode. It just goes really, really slow, but doesn't work hard or bring up the fan. It looks like the Microsoft progress histogram thing that appears before login is fake, but I could be wrong about that. I tried the built in quick scan which is not up-to-date, and did not find anything.
 
Forgot to say: On 1st attempt to boot the computer went into System something(?) and I tried this again another time. It stayed on about 15 minutes each time, then completed, but could not read what it said it had found as it flashed by. After that, attempts to boot got to the login within 5 minutes but would not finish after login.
 
Although I think it would be possible to use the Lenovo One-Step utility to restore to factory default, there is reams of work that is extremely difficult to save and concerning which I have been unable to find a less time-consuming way to keep up with saving it. The larger part, unsaved, has been accumulating since July and it would be terrible to lose it.
 
The computer is a Lenovo G550 laptop with Windows 7 Home Premium and 200 GB Hitachi hard drive. The Intel works has built in graphics.

We need a deeper look to do this safely.

Please follow this Preparation Guide and post in a new topic.
Let me know if all went well.

Thanks, boobme, for the instructions, and links partly about saving work. I MUST take this seriously and find a way to do it. Luckily, after years of searching, have just found an easy way of saving multiple .kml files from Google earth, which I work with a lot, and which doesn't seem to be posted anywhere on the internet, though people are always asking how to do it. (In order to get the file to open it must be saved with a different name than it was produced with, i.e. My Places.kml (just so, and nothing else.) Was able to recover all but the last two weeks that way, hurray.

 

Am thinking the best way to save every file in the system all at once on a daily basis might be to get an external hard drive, though it bugs me that system-restore-to-restore-points is out, since no amount of manipulating the settings will get it to produce restore points on a regular basis. This hard drive is getting old though, so am thinking external (plus replacement) might be the accident-proof pro-active way to go and would welcome your further suggestions for reading or action on this.

The safest practice is not to backup any executable files (*.exe), screensavers (*.scr), dynamic link library (*.dll), autorun (.ini) or script files (.php, .asp, .htm, .html, .xml) files because they may be infected by malware. Avoid backing up compressed files (.zip, .cab, .rar) that have executables inside them as some types of malware can penetrate compressed files and infect the .exe files within them.

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 - 3 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.
