I have Windows 7 on my lap-top computer (64-bit).
Earlier this afternoon Avast (Free) alerted me to a threat detection. I had Thunderbird open. I was advised to do a boot-time scan which I did.
I opted for no 2 on the list of options given to me - automatically fix all, I think.
The process took some time and 3 different threats were indicated Win32:Dropper-gen (Drp), Win32:Adware-BGF (PUP) and Win32:Malware-gen.
These are now quarantined.
My question is, do I need to do anything further with this information and is my computer still compromised?
In the last few months, I have had quite a few email threats detected which Avast tells me have been dealt with.
My question is, do I need to do anything further with this informatio and is my computer still compromised?
if you want a extra check, follow instructions and attach (not copy and paste) Malwarebytes and OTL logs https://forum.avast.com/index.php?topic=53253.0
Note: You need to run the version compatibale with your system. If you are not sure which version applies to your system download both of them and try to run them.
Only one of them will run on your system, that will be the right version.
[*]Double-click to run it. When the tool opens click Yes to disclaimer.
[*]Under Optional Scan ensure “List BCD” and “Driver MD5” are ticked.
[*]Press Scan button.
[*]It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
[*]The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.
WARNING: I noticed you have more than one antivirus installed.
Never install more than one Antivirus! Rather than giving you extra protection, it will decrease the reliability of it seriously! The reason for this is that if both products have their automatic (Real-Time) protection switched on, your system may lock up due to both software products attempting to access the same file at the same time. Also because more than one Antivirus installed are not compatible with each other, it can cause system performance problems and a serious system slowdown.
Please uninstall either Avast or Zone Alarm or Microsoft. You can leave only one.

Thanks for advice. I have uninstalled Microsoft Security Essentials and ZoneAlarm.
I have done all the things you suggested. Attached are the two log files.
I hope there is nothing suspect left!
What do you suggest as best practice going forward?
Thanks very much for your help.
Until yesterday, when avast notified me of malware etc as a result of the boot-time scan, I was unaware of any problems. My computer seems to be running normally now as it was before I started all this.
Reading other posts in this forum I’m aware that I must now uninstall the programs you have used to check for threats. Is this correct?
I’ve just been reading about cryptolocker and wonder how to guard against becoming infected with that.
