I sure hope someone can help me here. Yesterday my computer was running awfully slowly so I did a Malwarebytes scan (free version and updated). The scan listed 20 PUP opt.b infections so I clicked on them to remove all of them. As soon as I did that, I restarted my computer BUT when I clicked onto Internet Explorer, I could not connect to any website at all! Not google, Outlook, Facebook, NOTHING! So I went back to look again at the log of the scan and I found all of the items the scan found on the 22nd of October at 11:29 AM and clicked each one and restored them all! Then I could connect to all the websites again! I noticed that a few of the PUP optional b infections were in files, folders, and some were in memory, some in registry keys and registry values. I scanned again and removed all of the PUP infections except for the ones that said registry or memory; same thing after removal: I could not connect to any website through Internet Explorer. I even restored my computer to the 21st of October using system restore. Right now by leaving all thePUP infections listed and not removing them, I can reach websites. However my computer is still very slow to respond. Any ideas on what I should do? My computer is Vista premium home version with 64 bit. I am not a computer expert at all so any instructions you might have for me would have to be quite detailed and clear and easy to follow. Thank you in advance for your help.
