They said to uninstall it, reboot it, and repeat until avast started to work again. However, when I went to run a full thorough scan, it wouldnt start up (itd be stuck at 0 and never progress).5.

To speed up a scan, clean out temporary (junk) files first, temporarily disable any other real-time protection tools, close all open programs, perform a Quick Scan instead of a Full one and do not use the computer during the scan. I ran a quick scan, it said there was nothing to be found. Custom Scan allows the user to select any files and folders on the hard drive to be scanned.I did but now it reboots to a black screen and nothing shows as if were working and you can cancel the scan. Most Full Scans can be scheduled to run late at night when not using the computer so you can perform a weekly scan without having to monitor it. I installed Avast on an HP Laptop, ran the scan and it found a few things and suggested I run the boot time scan and restart. The length of time for performing a Full scan will also vary but because it is so comprehensive, this type of Full Scan is much more comprehensive since it scans the entire hard drive (all folders/files) which can number in the thousands.The length of time for performing a Quick scan will vary but it generally takes about 15-30 Quick Scan only checks the areas of your computer most likely to contain malware.the most prevalent and common places where malware typically hides.
