decompression bomb detected PLEASE ANSWER

Avast Free Antivirus / Premium Security
1

I ran a boot time scan yesterday and nothing was found. Today all ive done on my laptop is download malwarebytes and browse websites like target and walgreens. After doing so, i ran a boot time scan w/ avast and 3 decompression bombs are found and i dont understand why they are located in these file names. I also dont understand why these weren’t found yesterday or in any previous boot time scan. Can someone please explain why this would be?

c:\program files\TOSHIBA\TOSAPINS\COMPS1\TC…exe (2 of these)

c:\Users\Kevinx\AppData\Local\Google\Chrome\User Data\Default\cache\f
_000d

Also, i cannot locate the second file path (users\kevinx\appdata). The folder is not in there and ive checked everywhere. Can somemone tell me if i should be concerned about this or explain how to find this file path please?

Is a decompression bomb a threat? Is it normal for decompression bombs to all of a sudden appear???

Decompression bombs are large compressed files, and not necessarily a threat. It’s called a bomb because, metaphorically, it explodes into a large file when decompressed. Th files you enumerated seem to be clean, though.

You may get rid of some of those by clearing your Google Chrome’s browsing data, or let third party tools handle it. I suggest CCleaner for this task.
