Here is my log file from hijackthis, I deleted all the unnecessary lines -
O2 - BHO: Web assistant - {9ECB9560-04F9-4bbc-943D-298DDF1699E1} - C:\Program Files\Common Files\Symantec Shared\AdBlocking\NISShExt.dll
O3 - Toolbar: Web assistant - {0B53EAC3-8D69-4b9e-9B19-A37C9A5676A7} - C:\Program Files\Common Files\Symantec Shared\AdBlocking\NISShExt.dll
Does this mean that Web Assistant has changed 2 of my antivirus files? If so, would deleting them screw me over even more or would deleting fix the problem?
