I have an Acer Aspire X1430 desktop running Windows 7 Home Premium 6.1.7601 Service Pack 1 Build 7601 on my bench currently that I am trying to fix for a friend.
He reported slowdowns and performance issues. His Windows install was behind the times in terms of updates, so updated it through the control panel Windows Update to latest patches.
After uninstalling McAfee (installed by prior techs at Office Depot unfortunately) and installing Avast, ran a scan and removed several hits that were PUP related.
Also installed and ran Malwarebytes, which also picked of PUP related files and removed them.
After that, both Avast (boot time scan) and Malwarebytes scans report back clean with no hits.
However, the browser (latest version of Firefox, uninstalled and reinstalled it) is still lagging a bit, so I thought I should post here and make sure that all traces of infection are truly removed from the machine.
edit: It may be unrelated, I don't know, but the icons for Malwarebytes shortcut that is pinned to the taskbar keeps changing to a generic icon.
Any advice would be much appreciated, thank you for your time.
