I've been having a lot of trouble with my laptop ever since I got my new phone, the HTC One, a few days before Christmas. I was having trouble connecting it to the laptop (running Windows 7 right now) so I tried looking online for help and most posts I saw suggested certain programs, like Driver Whiz, for the drivers. Unfortunately, a few days after downloading all of what I did, I noticed that my computer was running incredibly slowly.

 

I tried deleting some of the programs. A few showed that they were uninstalled. A couple others, including Driver Whiz, wouldn't uninstall. I figured I downloaded something malicious at that point and downloaded Malwarebytes to see what was up. I ran a full scan and it took slightly longer than 28 hours to complete, and it found over 100 things that it felt were malicious. There are currently 101 items quarantined in Malwarebytes, with all but one of them starting off with "PUP.Optional." and with most of them ending with the name of one of the programs I downloaded. I'm assuming I should delete all the items quarantined, but I wanted to double check first. I should've posted this earlier.

 

My laptop started running a bit faster after I deleted what I could, but it's still running very slowly. I can't really get Firefox to work at all and Internet Explorer is really laggy. Some of my keystrokes aren't registered with Internet Explorer.

 

I ran Trend Micro Housecall after the Malwarebytes scan and after I removed what I could and it detected nothing, but my laptop is still operating unreasonably slowly.

 

I didn't have an antivirus at the time. I thought I was using Avast, so I will be downloading that again soon. That's a bad oversight on my part. I wasn't doing anything out of the ordinary and I'm pretty cautious about where I go on this laptop (no porn, no unrecognized links, anything someone suggests must be verified by that person before I click it so I can make sure they aren't infected with some Facebook bot or something...). I guess I got careless because of that.

 

I would appreciate any help possible. Thank you in advance!

I believe you may be infected, you need a post in am I infected there some very knowledgeable folks there follow their instructions to the letter.

Thank you very much for the suggestion. It looks like my post was moved, so hopefully, I'll get some replies soon. Anything at all would be greatly appreciated!

Can anybody help me? I really need my laptop for job applications and stuff like that.

 

A friend was able to remove some of the extra programs from my computer and clean it up a bit in Task Manager and I'm running scans through windows Defender and Avira Antivirus right now, but so far, I haven't really noticed a major difference in speed. I'm still using up way too much processing power just with Internet Explorer.

 

The first Avira scan I ran showed absolutely nothing. I'm doing a scan for rootkits and stuff now. I'm hoping to find something between the two scans that I can get rid of to make this thing run properly again.

I ran a scan with Windows Defender and found nothing. Avira found a couple of adware infections, but other than that, nothing, and I scanned for rootkits as well. I'm still using all of the laptop's processing power just to open up new tabs or run scans or even check my Facebook page, so something is still clearly wrong. I really need some help here. I don't know what to do.

I hate to bump this back up, but I haven't had any replies since January and my laptop is still extremely unresponsive. I desperately need some help. I need this laptop for job hunting, school stuff, my personal life, gaming, and more.
