Firstly welcome to GeekstoGo
In view of this
I did run malwarebytes and it removed a pub.bundle.installer.ol virus
and good as Malwarebytes is, you cannot rely on that or any other one such program to ensure your computer is now clean of all remnants of the malware.
On this site only our specially trained and qualified malware experts may deal with this issue.
Please go to this link
http://www.geekstogo...cleaning-guide/Follow carefully the advice in the link please and would you kindly post back on here simply to confirm you have seen this post.
Please be patient, if you create a topic in the Malware forum as they are very busy.
If after you have a clean bill of health from there, then if problems remain, you may most properly resume on this thread here.
What I can tell you is irrespective of the Malware aspect, this computer will of course never perform, in comparison with a more up to date one, as the processor at 1.4Ghz and the ram at only 512Mb are on the lower limit of performance.
That is not to say that you should not still follow the advice and indeed, not to suggest that an improvement cannot be made.
It is only to point out that when comparing speed of performance, you must compare like with like.
A 3Ghz processor with 2Gb ram running XP will always make this computer look extremely slow.
