I was browsing Wikipedia this morning when a McAfee popup (which has been expired for 13 days) indicated that I have a Potentially Unwanted Program. I opened it up to learn more about it and did some tinkering. I tried to do a full scan, not really expecting much since as I said, it was expired, so I was surprised when it actually scanned.
It detected the potentially unwanted program (PUP-FIW I think) and took a while to scan the rest of my computer. It got up to 99% scanned, but it got stalled after that. I turned off the computer, turned it back on, and tried to scan again. When I got on the internet, it didn't load my homepage. I ended up doing a total of three scans, the third of which is ongoing as I currently type this (it's also stalled on the at 1%).
On my first scan, I managed to isolate the PUP, but then it scanned a second time and the PUP popped up again. When I tried to isolate it a second time, it didn't work. Then I tried to scan a third time, which is as I said on the last 1%, and so far it hasn't detected the PUP. While it was scanning the first and second time and when I went on the internet, McAfee would send new popups on new PUP's, which looked similar to the first popup except the last digit on its number were different.
Just so you know, I got this laptop as a birthday present around a month and a half ago with McAfee already installed for a set period. It's a Dell Inspiron 15 5000 Series with Windows 8.1. I've been using computers all my life, but sadly I'm not very technology literate, relying mostly on family members to solve computer problems. I'm not quite sure I know what I'm doing.
Also I had issues yesterday with my computer too. On Wednesday I was browsing the internet when the internet just sort of froze. When I tried to click something on the website, it would take so long to load that I'd just give up and exit. I turned off the computer and turned it back on, but it didn't solve the problem with the internet. I went to sleep since it was midnight and did a system restore on Thursday to an earlier point. It didn't restore as smoothly as I hoped since a lot of pre-installed apps weren't working, so I had to download them again. I thought everything was good until today, and then the PUP happened.
I've already had a couple of scares before with the mouse not popping up or a black screen when I turn on my laptop, but it always got fixed when I turned my laptop on and off.
I'm afraid of something screwing up my computer now, so I'm thinking about potentially downloading another free anti-virus from the internet, possibly AGV. I'm also thinking about doing another restore, but I read somewhere that you shouldn't do it when you have a virus since it could just make the problem worse. I also read that there could be problems if I downloaded an antivirus while my laptop had a virus. I'm not sure if I have a threat on my hands, if it got fixed, or if it was never a problem in the first place. And why is my McAfee detecting, scanning, and potentially getting rid of viruses, PUP's or other problems when it's expired?
I'm so confused.
